Avoid the hazards of the internet

Using the Internet is one of the most dangerous daily activities that any given person will undertake.

Admittedly, the odds of bodily harm, other than carpal tunnel, are slim.  The danger, rather, lies in the potential impact web browsing can have on your personal identity and financial standing.  Every computer connected to the Net is a target of intrusive adware, malware, viruses and phising (explained below), all of which are secretly and routinely installed onto personal computers without the owners’ knowledge.  The nefarious individuals and shady businesses behind these intrusive and invasive software programs have one purpose in mind: to collect personal information about you and make money from what they learn about you.

Collectively, adware and malware are sometimes referred to as “spyware,” a term referring to software that snoops on and records your online activities.  Some tamer viruses can also fit into this category.

Adware (short for “advertising software”) is software that collects information about your web browsing patterns and uses the information to force ads to pop up on your screen.  Annoying at best, adware can clutter a computer to such a degree that it virtually freezes your machine while you are online.

Malware (short for “malicious software”) goes a step further by changing settings on your computer and harvesting personal information about you, including credit card numbers and other important financial information.  Malware can literally prevent a computer from operating, but even worse, keylogger malware software can record every key stroke you type, and from that information steal your passwords, credit card information and even social security number.

Viruses can be even worse than malware.  Installing themselves on your computer, they can perform a number of malicious functions, including stealing files and financial data, keylogging, spreading the virus (or spam) to everyone in your email address book, and taking control of your machine for the purpose of hacking (infiltrating) other computers.  Some persons who create viruses do so expressly in an effort to hack into and gain control of your machine in an effort to cover their own tracks (computers can be traced on the Internet; routing internet data through a series of machines helps obscure the originating machine).  

Phishing is the newest twist on Internet fraud, and refers to bold and deceptive attempts by thieves to obtain your credit card numbers, social security number and other important financial information (basically, your identity) by masquerading as legitimate businesses or organizations, such as eBay, PayPal or your local bank.  Appearing in both emails and on fraudulent websites, these schemes are often very believable on the surface (just as some counterfeiters produce excellent knockoffs of $20 bills).  Phishing is a serious threat to consumers who are frequently unable to distinguish between fake and legitimate requests for information.

All in all, web browsing is a very dangerous activity because it endangers your very identity, which if stolen, could wreck your life financially.

So, how does one avoid adware, malware, viruses and phishing schemes?  The following five steps will help you have a safer web browsing experience.

1.  Use a safer web browser, such as Mozilla Firefox.  Microsoft Internet Explorer, especially used in conjunction with Microsoft Office products, is much more susceptible to adware, malware and viruses than Firefox, Opera and some other lesser known, but very good, web browsers.

2.  Whatever web browser you do choose to use, be certain to download all updates and familiarize yourself with the built-in safe surfing features, and tweak the settings to ensure a high degree of protection.  Most web browsers are now able to warn you if you are about to go to a fraudulent site (especially a phishing site) or if a download poses a possible risk.  (Note: No web browser is able to identity every fraudulent site or risky download.)

3.  Be very careful about downloading any software file off the Internet!  Adware, malware and viruses frequently “ride in” atop music, video and other files.  As a rule of thumb, do not download anything from the Net unless it is from a trusted source … and even then be diligent, as some trusted Net companies have utilized adware companies to pitch their products.

4.  Use anti-adware, anti-malware and anti-virus software religiously.  A number of reputable companies offer security software.  While most products require a subscription, some excellent software is still free (at least at this point).

If you are accessing the Net through a broadband connection, install a router between your computer and your modem; routers act as an external firewall, hiding your computer’s identification (IP address, or Internet Protocol address) from would-be intruders.

5.   Control who uses your computer.  Teenagers especially are frequently unaware that their music and video downloads can be dangerous.  In general, assume that anyone other than you using your computer does not know how to prevent adware, malware, virus and phishing.  Their lack of knowledge could endanger your identity.

When you need computer repair – how to choose a company

Computer repair is a common need these days. A large number of us work with PCs at our places of business, and many of us have them in our homes as well. A few people are lucky enough to have the technical savvy to be able to fix most problems that arise, but that doesn’t describe most of us. There are times when we need to call on the services of a professional to get our PCs healthy again after they run into problems.

Assessing the Problem

Though there’s a good chance that you may not know what caused your PC problem, you can at least take note of what the problem is. For instance, your PC keeps freezing for no apparent reason, or it slows down so much that it becomes impossible to use it effectively. That’s a problem, so write it down. Many times, multiple problems come up at once, such as a computer that keeps freezing, shows frequent error messages, and has lost its sound at the same time. Write all this down, because it will help you choose the right computer repair service, and it will help that service diagnose and fix the issue

Who to Call

A good guideline to follow when deciding who to hire to for your computer repair is to start small and local. Ask friends or business acquaintances if there are any local shops that they’ve used when they’ve needed their PCs fixed, and ask if they were happy with the service. Smaller, local businesses are usually eager to build a loyal customer base, and they’ll often go above and beyond when it comes to customer service. They are also more likely to take the time to educate you about the issue, how they fixed it, and how you can prevent it from happening in the future. Sometimes, however, the problem might be too big, such as hard drive damage. In that case, it might be better to contact a larger company that provides a wider range of services.

Learning from the Experience

No matter who does your computer repair; do not be afraid to ask questions about their diagnosis and what they did to fix the issue. Learn from them as much as you can, and there’s a chance that you won’t need to pay for help if the problem happens again. A reputable repair service will be glad to teach you a few things; it’s just another way for them to build customer loyalty.

When it comes to computer repair, you want to make sure that you choose the right service to help you. When you doHealth Fitness Articles, keep their number handy; you never know when another issue will arise.

Getting rid of an old computer? Don’t become an identity theft victim, WIPE IT!

There are often questions asked when changing or buying a new computer about the process of Hard Drive Wipe. The process for wiping or cleaning your personal data is quite simple as one might think. To completely wipe off your data you will have to write over the data. Simply reformatting the drive or just deleting all the files will not help. Fortunately there are a number of inexpensive and free wipe programs, which are also called as shedders can cover the data with random pattern or zeroes, which makes the data restoration software unreadable. However, there are some machines that can recover the data that has been written over only a few times. This is where the secure erase standards like the department of defense 5220.22-M will have to be referred. The specification of this read as, if you overwrite the drive three times according to the specifications it would be difficult to recover the data. However, a number of professionals would recommend you to overwrite the data seven times to ensure you have completely wiped off your hard drive making it completely unrecoverable. Sometimes reading the data that has been overwritten by a shredder would require expensive hardware, so if you are not worried about the professional data thefts then a careful overwriting is also not required.

One thing that your must always keep in mind is that just deleting your sensitive file or data will not protect you fully. This is because there may be unidentified copies of your file or data that can exist in some unused part of your swap files or in the hard rive and can also be in other possible locations. You can be on a safer side if you just wipe off your entire area of your hard drive or you can just go the definite route and clean up your entire hard drive. If you want to wipe off specific files and the free space of your hard drive then there are a number of software’s that can help your and even software’s to overwrite your hard drive three times.

If you want to get rid of your old hard drive or want to sell off your old computer it is very important that you take maximum precautions in cleaning off all your personal and sensitive files or data before selling off your hard drive. Although it is very difficult to recover the lost data on any hard drive it is not also impossible. However, data can be recovered at some degree. This task can be made impossible, if you follow proper specifications. One thing you should always keep in mind is that deleting files or data or just formatting your hard drive is not sufficient to completely wipe off your hard drive. To be sure that you have completely wiped off you fines you should use a erasing or wiping service. There are tools to help you clean off your hard driveBusiness Management Articles, which will overwrite every sector on your hard drive. One of the most important things you must remember before selling off your hard drive or computer is preparing your hard drive or emptying it to be on a safer side.

Backup your data!

In today’s world of digital photography, digital music, and word processing there is absolutely no excuse not to back up your data.

Just this week, I had two different customers who had not backed up their data and had physical hard drive failures.  In one case the hard drive would not even spin up, and in the other the hard drive would just click.

What was lost was more than just 1′s and 0′s (well, not really), but photo’s of precious memories & family events.  The users had digital audio files, and important documents such as Quicken data and documents such as resumes, letters, etc.

Hard drives are one of the only moving parts to our computer.  We competely understand when a part in our automobile engine wears out, or our tires need to be replaced from wear and tear, but some how the elusive hard drive gets often forgotten about.

Usually, for less than $100.00 a user can purchase an external hard drive and back up their data, keeping it safe from hard drive failure or accidental deletion.

Please folks, go to your local computer store and ask about backups / data protection today.  You never know when your hard disk will have a bad day.

Do it yourself Virus & Malware Removal

Virus Removal can be difficult, but here are some steps you can take yourself to try to get rid of virus’.

First however, CCW Technology believes that it’s better to prevent the virus before you get it. We recommend AVG Anti-Virus and Malware Bytes.

These two programs are recommended by most IT Professionals. CCW Technology can help you purchase, and install these programs for the best defense against Virus’ and Malware.

Basic Virus Removal Tips: (CCW Technology Provides these tips as a courtesy, nothing is a substitution for professional technical support and as such, provides these tips at your own risk and without warranty)

Virus Removal Step 1: Turn off System Restore. Often times when you attempt virus removal, system restore will inadvertently bring the virus back.

Steps to turn off System Restore:

  1. Click Start, right-click My Computer, and then click Properties.
  2. In the System Properties dialog box, click the System Restore tab.
  3. Click to select the Turn off System Restore check box. Or, click to select the Turn off System Restore on all drives check box.
  4. Click OK.
  5. When you receive the following message, click Yes to confirm that you want to turn off System Restore:
    You have chosen to turn off System Restore. If you continue, all existing restore points will be deleted, and you will not be able to track or undo changes to your computer.

    Do you want to turn off System Restore?

    After a few moments, the System Properties dialog box closes.

Virus Removal Step 2: Delete Temporary Files
There are a number of files/folders/programs that you can make use of once and never need again in the future. They tend to accumulate on your system and consume much space on your drive, resulting to slow processing of tasks. To enhance your computer’s performance while doing a scanning process, I would strongly suggest you to sort and delete them. This will result to a faster and more effective virus scanning process.

Your computer can get infected simply by accessing a web site. And information about visited web sites is stored in your Temporary Internet Files folder to facilitate an upcoming access to these web sites. However, these files can be infected and also tend to take a lot of space in the long run. Deleting these files would allow you to remove corrupted files from your system while allowing your computer to perform faster.

How to delete Temporary Files?

  • Click on your Start Button and select the Accessories option
  • Choose System Tools and from the list, choose Disk Clean Up
  • When the scanning process is over, always click on View Files to check whether these files found can be removed from your system
  • You can also check more options in the Files to delete list. (Temporary Internet Files, Downloaded Program Files, Offline Web Pages as well as the Recycle Bin can be checked)
  • Confirm the changes when prompted and click OK

How to delete Temporary Internet Files?

  • Click on your Start Button and open Control Panel
  • Select Internet Options
  • From the General task, under Temporary Internet Files, choose Delete Cookies and Delete Files .
  • Confirm the changes and click Apply

Virus Removal Step 2: Use a Anti-Virus Live CD

Use a good anti-virus LIVE CD. A live CD is one which you boot your computer into rather than one you use within windows. AVG provides one for free called the AVG Rescue CD. For details on use, see AVG’s web site.

Virus Removal Step 3: Use Malware Bytes anti-malware. The free version is awesome, however I would recommend the paid version as it includes a memory resident protection, as well as it auto-updates and protects you automatically from the latest detected threats.

Virus Removal Step 4: If you have removed all of virus’, pat yourself on the back and re-enable System Restore. If not, it’s time to call for help. CCW Technology can help you remove virus’ and help to protect you in the future. Remember, virus’ and malware are responsible for a large amount of data loss each year. Don’t let your family financial records, precious photographs, or other important data get destroyed by not being properly prepared. Call us now for help.

Steps to turn on System Restore

  1. Click Start, right-click My Computer, and then click Properties.
  2. In the System Properties dialog box, click the System Restore tab.
  3. Click to clear the Turn off System Restore check box. Or, click the Turn off System Restore on all drives check box.
  4. Click OK.After a few moments, the System Properties dialog box closes.

Help Keep The Computers On Earth Clean And Healthy: Protect Your Techno-Friends From Viruses And ‘Sickness’

Help keep the computers on Earth clean and healthy: Protect your techno-friends from viruses and ‘sickness’.

“Aaaaaahhhhhh! I’ve been invaded by a virus!” Getting a virus means getting sick and no one in their right mind wants to be ill. Well, now that computers have become our close friends, it’s a shock to learn that foreign bodies too can invade them with malicious intent. No, your computer doesn’t get a runny nose or diarrhea. This is a sickness that stops your friend from functioning properly, sick in bed, incapacitated.

Well in Nature viruses occur from a power outside of our control. But, with computers it’s different, humans, mean or ignorant humans are creating these viruses. Why? Usually these are disgruntled people who want to wreak some havoc on others or companies that they feel have done wrong to them. In any case we have to be in the know and prepared to deal with these debilitating scourges.

There are many ways to approach the protection of your computer. First of all there’s the step of awareness. Be aware of how viruses are transmitted. You can catch them from a disc but in most cases it is through your email system. Check your email carefully. Be very wary of anything that has an attachment. Check whom it’s from and look at the title of the mail, is it something you were expecting? Even if it’s from someone you know, be careful as their computer could be infected and the virus being transmitted without their knowledge.

Next, read the cover message, you can’t catch the disease without actually opening the message. Look at the name of the attachment; remember viruses are written to entice you. Beware of free offers and generally anything from people you don’t know, as well as messages that sound irrelevant to your contact’s usual style. Delete them straight away. Delete, delete, delete. This will ensure you of a lower risk of infection. You can even send the message back to the sender without opening it to make sure it is valid.

Now for the heavy protection: Virus scanning and virus protection software, and rescue discs are all readily available and easily utilized. Some are free, and others are obtained for a very small charge. Most software manufacturers offer subscriptions for updating services, which automatically download protection to the latest viruses.

There are two main types of virus scanning software: one searches through your entire computer files looking for recognizable viral signatures, the other scans your incoming and outgoing emails. Alerts will show you when a file needs to be erased or repaired. If you do receive a virus that none of the software can repair you can send a copy of it to a company like Symantec who will be happy to develop a cure for it.

The main message here is not to get too worried about your good friend Mrs. PC getting ill or sick. The humans are on top of the case and they seem much better adapted at fixing their technology than they are at beating the viruses that attack our physical bodies. If only we could cure human virus and illness as easily as we solve the problem of computer sickness.

Computer Tips that Help Small Businesses Operate Profitably

When working properly, computers enable small businesses to make big business profits; however, get booted off your computer and you’re suddenly starving. In most instances, computers usually act up due to lack of care by its owners. Here are four computer tips that’ll keep you up and running smoothly.

Tip #1 — Back up your computer’s data no less than once a month.

Too often a small business is thrust back to infancy because it didn’t take time to back up precious data; information that took hours upon hours to create. Information that’s irreplaceable, such as customer databases or employment contracts. Keep in mind you’ll want to back up your written data as well as check books such as Quicken and email address books. If your computer has a CD writer, it’s simple and quick to back up your data. Simply select the files and folders you want to back up and copy them to the writer.

Or if you have an older computer, copy your most important files to a floppy disk. Either way, don’t stop there; now take the CD or disk and store it in a fire-safe box! To expedite the process, organize your files within folders so you can quickly grab and copy one or two folders.

Tip #2 – Don’t turn off your computer every evening.

Too frequently computer users turn their computers off every evening. This is unnecessary and not recommended. A computer’s components are at their most vulnerable when turned on and off. When a computer has to heat up [turn on] or cool down [turn off] it’s at this precise moment components fail. It’s recommended you turn your computer off once or twice a week or only when necessary, such as from a power outage. However, don’t do the opposite and never turn your computer off, since many anti-virus programs require a computer reboot be performed before new virus patches take effect.

Tip #3 — Automate anti-virus software so it updates automatically no less than once a week.

Depending on your software, you may need to prompt it to update. Unfortunately, there are people with too much time on their hands who desire to attack and make your computer unusable. A computer user is not ultimately protected from viruses and spyware [pop-ups, cookies, etc.] unless you’re using a combination of anti-virus and anti-spyware software and a firewall, a piece of hardware that protects computers from being hacked. You must have all three pieces in order to ward off viruses, lurkers and attacks. What’s more, most of the attacks are very quiet. You don’t know someone is on your computer. Instead, they secretly store information, such as child pornography or music MP3s on your computer, since it’s illegal, and redirect child-porno or MP3 seekers to your computer instead of theirs.

Tip #4 — Install a firewall if you keep your computer constantly on.

Using a broadband or DSL connection dramatically increases your exposure to being hacked. It only takes an average of 15 minutes being online before a home-based computer is attacked. The only true way to protect a computer from a hacker is to install a hardware firewall. It’s a misconception that software-based firewalls ultimately defend computers. This is simply not true. Computers must have a hardware firewall for ultimate protection, such as a SonicWall or Netscreen firewall, a component installed between a home user’s cable or DSL connection and their computer.

Cleaning Your Computer Will Help It Last Longer And Work Better

To clean your mouse – The trackball can pick up dirt and dust from your desk and mouse pad. Also, the wheels that the trackball come in contact with get dirty and need to be cleaned. If you notice your mouse “doesn’t work right”, it may be time to clean it. First, turn your PC off. Turn your mouse over and you will see the ball sticking out of a cover. Look at the arrows on the cover and turn it in the indicated direction to open it up. Don’t worry about anything falling out. The only thing that comes out is the ball, and maybe a little dust, and you want to take that out anyway. You can clean the ball with alcohol if it needs it, but usually just wiping it off will work. A cotton swab dipped in rubbing alcohol works well for cleaning the wheels. When you’re done, drop the ball back in and put the cover back on. If cleaning it doesn’t help, it may be time to replace it. PC mice are usually less than $10 and are sometime free if you watch for sales in the Sunday paper.

To clean your optical mouse – If you have an optical mouse, one with a red light under it, there is no ball and you can just wipe off the lenses with a cotton swab.

To clean your keyboard – Never spray anything into your keyboard, this includes coffee. You can use a vacuum cleaner to clean dust, dirt, staples and cookie crumbs from your keyboard, but make sure your computer is off before starting, and make sure you don’t have any loose keys. Rubbing alcohol works well to clean the keys and surface of your keyboard, but use it sparingly. Using a cloth works well, as paper towels tend to leave little pieces behind. If you spill something sticky like your favorite soft drink on the keyboard, the keys will likely start to get sticky as it dries. It could be time to replace it. They too are cheap and can be free if you watch for a sale.

To clean the computer – You can use a vacuum to clean around the vents and anywhere else that looks dusty. Be careful in the back of the PC to not knock any plugs loose. It is a good idea to keep the vents clean and free of dust, pet hair or lint. How often you clean your computer depends more on the environment it’s in than the manufacturer’s recommendation. I have 2 dogs that shed so I clean my computer about every 2 months. A cloth and alcohol can be used on the outside of the PC if it’s dirty but, again, turn it off first.

To clean your monitor – A vacuum can be used to remove dust from the vents. If you have fingerprints on the glass, you can use the same wipes that you would use on your glasses or use as soft cloth and warm water followed by a dry cloth. Think of your monitor glass the same way you think of glasses, if you wear them. They may have delicate coatings on them that can be scratched. Always avoid chemicals on displays.

To clean a laptop display or LCD – These displays are plastic and can also be scratched by paper products such as tissues or paper towels or damaged by chemicals. Use a cloth made for glasses or camera lenses or a soft cloth and warm water followed by a dry cloth.

Why you should develop a relationship with a computer repair company

While many small companies only call in a local computer consulting business when something computer-related breaks, there’s a lot to be gained by forging a proactive, long-term relationship with a local computer consulting business in your area.

Consider Getting Advice from a Computer Consulting Business

If you need to get advice once-in-a-while on how your computers can be better utilized, or you have a specific computer-related problem that needs to be solved, a computer consulting business is generally the way to go.

However, if computer-systems and information technology (IT) are really important to your industry and your company, outsourcing your computer-related service needs to a local computer consulting business is often a much better solution than just piecemeal, ad-hoc usage of a computer consulting business.

Hiring a Computer Consultant

Many computer consulting businesses choose to specialize and end up becoming extremely valuable to their particular area or niche. In many cases, these kinds of computer consulting businesses can know almost as much about your industry and competitive challenges as you do.

So to help your company grow and to make sure it’s not being short-sighted with its computer-related needs, consider getting advice from a computer consulting business.

Wearing Lots of “Hats” is Fine… But Don’t Let These “Hats” Blind-Sight You

Sometimes small companies already have an idea of what their computer-related needs are when they enlist the help of an outside computer consulting business.

There are several advantages to bringing in an outside computer consulting business, as opposed to trying to limp along with someone internally who just wears the “hat” of the occasional computer person.

One of the most important reasons to bring in a computer consulting business though is that a computer consultant is someone who is an expert in his or her field. This means you can have access to an expert for a fraction of the cost it would take to hire that caliber of professional on a full time basis.

In almost all cases, a computer consultant like this can troubleshoot problem much faster and much more effectively than your internal employees.

A Fresh Computer Consultant Perspective

A computer consultant or computer consulting business can also being in a fresh perspective to your company.

It’s often really helpful to have a fresh set of eyes to look at your company and its IT infrastructure. Over time, non-technical small business owners and managers have a tendency to see the same things within their own companies. A good computer consultant or computer consulting business brings a new and fresh perspective into your situation and can help you truly visualize the forest through the trees.

How Computer Consulting Businesses Help

A good computer consulting business or computer consultant is prepared to do any number of things to help your company make the most out of any business or technology challenge it faces. This may include personal coaching, training for small and large groups of employees, and leading strategy-planning meetings with key people… almost as if that computer consultant were your part-time chief information officer (CIO).

The best computer consultants will not enter into your company with a preset plan, but rather will tailor a plan according to the specific needs of your company. A good computer consulting business will have computer consultants on their staff who can quickly find out what the needs of your company are and then come up with cost-effective solutions.

The Bottom Line

In this article, you’ve been introduced to the basics of why to hire a computer consulting business and what computer consulting businesses can do for your company.

Protect your equipment with a surge protector

How a Surge Protector Can Help a Laptop Computer
 by: Stephanie Larkin

Electrical power spikes can be devastating to any electronic device, but the damage to a laptop computer can be even more significant to its owner because of the potential for lost information and reduced productivity. Safeguarding laptop computers with a surge protector (also called surge suppressors) is one simple and inexpensive way to lessen the risk of physical damage or lost information due to electrical surges.

Fluctuations in electrical service are common around the world. Known as power spikes, surges, brownouts, and blackouts, these fluctuations can cause anything from fire to data loss in an unprotected laptop computer. When power returns, it can come in a rush, rising significantly above standard household voltage levels to burn wires, overwhelm circuits and potentially cause damage to laptops, adapters, and any external peripherals that may be connected to the computer. Even when the power surge is not strong enough to knock out a system, it can slowly damage the computer’s components, reducing its reliability and lifespan. A surge protector diverts the extra voltage from a power surge to a ground wire, sparing harm to any connected electrical devices.

Most household appliances use 120- volt power (AC) – the level of electricity that you get from a regular electric outlet. Laptop computers covert 120- volt power to about 12 to 18 volts (DC) by way of an adapter that is usually located along the power cord. This conversion offers some measure of protection, but it never hurts to add the additional shield of a surge protector.

Surge protectors are inexpensive insurance for costly electrical gear. They also add functionality to most office environments, as they typically come in a power bar format that offers extra outlets. While most surge protectors are also power bars, not all power bars are surge protectors. Be sure to check whether surge protection is offered before purchasing a power bar. Power bars with surge protection may cost slightly more than a regular power bar.

Many office environments use surge protectors as part of their standard equipment configurations. However, portability is a key feature of laptops, thanks to their small size and alternate battery power, so laptop operators often find themselves using their laptops outside of the surge protected office. Ideally, laptops should be guarded by a surge protector wherever they are being plugged in, so a travel-size surge protector is a good investment. This is especially true in a hotel or large building where air conditioners, elevators or other equipment requires periodic bursts of large amounts of electrical power.

Not all surge protectors offer the same level of protection, and none can guarantee electrical equipment won’t be damaged if there is a severe power surge such as that caused by a nearby lightning strike. A powerful surge may also damage the surge protector, so try to find a model with an indicator light that goes out if the unit fails to function properly. There are several Underwriters Laboratories (UL) ratings (found on the label) that can help you choose an appropriate surge protector, such as clamping voltage, energy absorption and dissipation, and response time. Clamping voltage is the point at which electricity is diverted to the ground wire. Look for 330 to 400 volts. Energy absorption and dissipation is the amount of energy, in joules, that the surge protector can handle before it fails. The higher the number the better. A rating of 200 to 400 joules is adequate, but a rating of 600 joules or more will offer superior protection. Response time is the delay between the power surge and the surge protector’s diversion to ground. Faster is better, in this case, as the less time your laptop is exposed to the extra energy, the safer it will be. A response time of less than a nanosecond is desirable.

Power surge consumers who aren’t knowledgeable about electricity and UL ratings can also judge a surge protector by its price: more expensive models tend to offer better protection than the cheapest discount store models. Quality laptop travel surge protectors can generally be purchased for less than $50 (USD), and offer a variety of features including telephone and network/broadband Ethernet jacks, and universal plugs and sockets that will work in countries with electric utilities offering 100 volt AC service to 240 volts AC service. Some travel adapters have built- in surge protection that protects laptops as well as cell phones and personal digital assistant (PDA) devices. Most laptop surge protectors are designed with convenience in mind, and are compact and easy to pack.

The last consideration in purchasing laptop surge protection is the quality of the warranty offered by the manufacturer. Some companies will offer compensation if equipment is damaged by a power surge while it is protected with a functioning surge protector, but warranties vary, so read the fine print.
