Not Protected After All: Antivirus Infections Strike Despite Your Security Software.

You got your polio and whooping cough shots as a kid and you never came down with either of these dreaded diseases.

You might think that your security software on your computer works the same way. You took the preventative measures to avoid the infection, so you should be safe.

But, surprisingly, security software does not always provide the kind of protection to your computer that your childhood vaccines provide to your body’s immune system.

Your anti-virus/anti-spyware programs and firewalls can be made vulnerable through fake antivirus program scams that fool even savvy computer users.  The fake antivirus program scams arrived last year as “XP Antivirus 2008.”  It lives on in many variations, including “Antivirus 2009.” This scam is successful because it cleverly mimics Windows warning screens and legitimate antivirus programs. Virtually every legitimate antivirus company has a product called Antivirus 2009, so it’s no wonder so many computer users are confused–and duped!

Here’s how the infection scam works. You get an official looking popup warning or an e-mail message telling you that you are infected. To remedy the situation, you are instructed to click on a link that takes you to a website. Then you are told you need to download software.

As a result, you click on links that generate malicious code or downloads and runs questionable files. You will inadvertently override your own installed protection. In some cases, you will actually disable your protection programs! Even worse, the scam will make it look as if your protection programs are still running, so you will be none the wiser.

Any popup or error message that refers to Antivirus 2008 or 2009 (including System Antivirus, Ultimate Antivirus, Vista Antivirus, Pro Antivirus or XP Antivirus followed by a number) should be considered extremely suspicious. If you see any reference to a virus that is not specifically from the product that you have installed in your computer for protection, you should consider it a fake–and dangerous.

Windows won’t ever alert you of a virus infection.

Getting rid of the code once it has infected your system is quite involved. In our service business, we use a combination of several manual detection and removal processes, along with multiple scanning programs to recover your data. This ensures that all potential re-infection avenues (temp files, restore points, modified dll files, etc.) have been removed or restored. We routinely warn novices not to attempt this without help.

Depending upon how long and which version of the malware you have been infected with, you may also need to run a Windows repair after you remove the code. Certain Windows files become corrupted as a side effect.

If you know how to work with the Windows registry, operate in Safe Mode and have a current backup of your critical files, you should be able to find instructions online for removing the exact version of the infection that you have. If not, consult a tech savvy friend or a professional. Again, removing this infection so that you don’t re-infect is technically complex and not for the novice.

Cloud computing: What can it do for me?

Cloud computing has many different inferences but in its simplest description, it refers to using a computer that works solely off the Internet instead of from your computer’s hard drive. It offers businesses lower start up and maintenance costs and replaces those costs with monthly ongoing fees.

Instead of having to buy the machine, software, servers, and get everything installed, configured and working correctly, you can buy a simple off-the-shelf computer, connect it to the internet and away you go.  The ease of using the Internet for the average consumer or small business is that there are many free or low cost options through cloud computing available.

Gmail is a great example of a consumer cloud computing offering as it’s a very powerful e-mail system that is entirely housed and processed by Google’s servers.  Unlike Microsoft Outlook Express, you are not tied to a single computer to get your e-mail.   Another example is tax-prep software. Now with cloud computing you can sign up online and do your taxes from work, home or anywhere that you have a computer and can log onto the Internet  Or, in the more traditional manner you can buy the disk, install the software and then be responsible for backing it up and keeping track of all the data on your hard drive, hoping your computer doesn’t crash at some point and lose it all. The downside to cloud computing is that if you don’t have access to the Internet, or if your connection goes down or the host servers get overloaded or attacked, you have no way to access your data.  Another concern voiced by some has to do with data security.  Since it’s in the “cloud” critics says it’s exposed to various ways data can be compromised on the Internet.  However, one also has to realize that data can be exposed to security issues wherever you house the data. If your data is housed on  a hard-drive, you risk it being physically stolen or leaked by a hacker on the Internet.

Cloud computing IS for everyone, but it ISN’T for everything!  Weigh your pros and cons when deciding when and what to commit to the cloud!

What exactly is Windows 7’s XP mode and what is it used for?

Filed under: PC, Software, Windows 7 — Tags: computer repair, computers, hardware, Microsoft, RAM, Software, upgrade software, Win 7, Windows 7, windows xp, XP safe mode — admin @ 2:02 pm

Microsoft knew that it was going to have a tough time convincing hardcore Windows XP users to migrate to Windows 7 because some older applications and hardware (like scanners) that required Windows XP could not be updated to work in Windows 7.  Accordingly,  certain versions of Windows 7 have an optional feature called Windows XP Mode, which unlike the ‘XP Compatibility mode’ that was in Windows Vista, is an actual complete copy of Windows XP with SP3 (Service Pack 3) that can run as a ‘virtual’ system within Windows 7.

This means that older or outdated applications and peripherals that would only work in Windows XP can run in a virtual session that will appear as just another icon in Windows 7 (and it’s really cool how smooth it works!)

But, before you get too worked up about this creative approach to migrating older users and applications, there are some ‘requirements’ that you should know about. To support XP Mode, you will need a newer computer with a processor capable of ‘hardware virtualization’  (AMD-V or Intel VT), at least 2 GB of RAM and a recommended 15 GB of free drive space.

If you want to see if your computer is capable of supporting Windows XP Mode, you can run Microsoft’s Hardware-Assisted Virtualization Detection tool. In addition, the only versions of Windows 7 that support XP Mode are Professional, Ultimate & Enterprise edition which means that if you get the Home Premium version, which is the least expensive, you don’t have this option.

The reality is, you won’t need this feature to simply surf the web, exchange e-mails and write some letters; it’s only for those will special programs and older peripherals.  The XP Mode feature is a godsend to corporate IT departments as it provides a much more comprehensive way to migrate to Windows 7 without the expense of updating old custom programs that were designed to run in Windows XP.

What is very important to understand is that this is not a replacement for Windows 7 and should only be used for specific programs or devices that won’t work in Windows 7. For instance, if you plan on using XP Mode, you wouldn’t want to surf the Internet from within the XP session because it would expose you to all of the vulnerabilities that Windows XP has. Windows 7 is significantly more secure for web browsing in today’s hostile Internet environment (keep in mind, Windows XP was designed to deal with security threats that existed in 2001), so minimizing what you do in XP Mode is prudent.

As you may have already realized, this feature is not designed to be setup by the casual user, so if you think you might have a need for the feature, consult a knowledgeable technical resource or your local computer expert to review your specific situation before you spend the money on something you don’t actually need!

What makes Windows 7 better than Vista or XP?

Windows 7, the long awaited replacement for the much maligned Windows Vista is due to be released on Oct 22nd (although many custom-build computer shops like ours are already delivering Windows 7 systems.)  Even if the reasons for considering an upgrade to the new OS were not so numerous, the reality is that at some point most users will have no choice. No matter how much users like Windows XP, there will come a time when Microsoft won’t support it, including the very important security patches that plug security vulnerabilities.  With this in mind, the Windows 7 question isn’t really a question of WILL you upgrade, but WHEN will you upgrade (a month, a year, 5 years?).

By all accounts, Windows 7 is a significant improvement over Windows Vista, primarily because Microsoft has been able to strip out the bad and add lots of new good to make what is essentially Windows Vista 2. (They knew better than to call it that, though!)

Regardless of how it happened, Microsoft listened to the complaints of Vista users and continued to improve the built-in security to produce a pretty solid operating system.

Here are some of the major improvements:

It actually requires less hardware than Windows Vista. For those of us that have been around since Windows 1.0, we were shocked to learn that Microsoft didn’t ratchet up the hardware requirements like they have with every previous version.  Systems light on power that struggled to run Windows Vista will likely run better with Windows 7 (you will even see lots of Netbooks running Windows 7 shortly, which would be unimaginable for Vista).

A kinder, gentler and more flexible UAC (User Account Control). In Windows Vista, the UAC feature was so over-bearing (remember the humorous ‘accept or deny’ Apple commercials?) that many users simply turned it off, which disabled one of the best features that made Vista much more secure than Windows XP.  In Windows 7, you can decide where and how this very useful and powerful tool is implemented (a great way to control what the kids can and cannot add to the system). With the sneaky malicious software that is plaguing the Internet at the moment, this updated version of the UAC is just what most consumers and small businesses need to fight the malware battle.

Faster boot times. The goal from the engineering side at Microsoft was to target a 15 second startup time, which may or may not be possible for everyone (your start time will depend upon what additional software you install), but by all measures, the tech community agrees that 7 boots faster than Vista.

Easier home networking setup. Anyone that went through the nightmare of trying to integrate a Vista system into an existing Windows XP network will appreciate this improvement.

Better support for multi-monitor configuration. If you haven’t experienced the joy of having dual monitors installed on your home or office computer, you are really missing a huge improvement in productivity (add it to your holiday wish list, you will thank us for it!).  Windows Vista was pretty picky about what it would support, whereas Windows 7 has wider support for different video cards coexisting in the same computer for a dual display configuration.

There are a whole host of other improvements such as auto-sizing side-by-side windows, consolidated and clearer security messages, Taskbar previews that are actually viewable and control over those irritating balloon notifications in the bottom right corner that make Windows 7 worth considering.

At the end of the day, if what you are using is working fine, don’t be in a huge hurry to fix what ain’t broken, however, if you are struggling with security, stability or performance, Windows 7 may be just what the doctor orders!
