Virus? My computer has been sending error messages that I have a potential virus threat and provides virus protection options. WHen I select them it takes me to an advertiser page. Also, my wallpaper is changes and will not change back. When I select ctr -alt- dlt a message appears basically stating that the administrator has blocked this option. Finally, it will not let me download any virus removers and I believe the one I have is outdated because it doesn't find this virus. What else can I do?

Firstly, the most important thing you can do is keep up-to-date virus protection-either a paid program like "Mcafee" or a free version, (which I'm not sold on but better than nothing)like AVG.....available here:
http://free.avg.com/download-avg-anti-virus-free-edition

Ad/spyware blockers are important tohave as well.

How long ago did the problems start? a day or 2?
You could first try system restore.
"start", "all Programs", Accessories", "System tools", System Restore", "Restore My Computer to an Earlier time", and select a date before your troubles occurred...note that this WILL remove any PROGRAMS or UPDATES you have downloaded in the meantime, but NOT any files that you have created or docs you have edited, pictures added, etc.
Hopefully "system restore" is on and hasn;t been disabled by whatever is causing your problem (which is often the case).
If this works...great...go update your antivirus, etc.
If Not, try booting in safe mode...."Restart", and hold "F8" as soon as the screen goes black for the reboot, select "safe mode" and try running a virus scan from this mode.
You colud also try downloading (in regular mode) something like "spybot searcvh and destroy" to try and find your Problem> You can get it here:

Hope this helps...good luck ;)

Secure Your Windows PC For Free


With the online holiday buying season upon us, the most important thing to remember is computer security. Each day millions of threats cycle through the Internet, most of which harm computers and home networks. These threats hunt for credit card numbers, social security numbers, and other personal information and can be used against you in the form of identity theft. Here are some tips to help secure your PC and keep your information safe and locked down.

1. Windows Update
This is the number one reason computers fall victim to malicious threats (viruses, spyware, etc.) is not updating the Windows operating system. During the spring of 2009, the virus named "conficker" targeted computers that were not fully updated. To update the Windows, first the computer needs to be connected to the Internet, whether it would be wired or wireless network connection. Then go to Start > Programs > Windows Update. Let Widows Update complete and afterward your computer will be up-to-date.

2. Anti-Virus Program
Some sort of anti-virus software should be the bare minimum for computer security. Not having protection can increase the chances of viruses, trojans, spyware, adware, and identity theft. There are some free as well as paid versions, but for basic web surfing and email free versions will work just fine. Here are some recommended free anti-virus programs.
AVG Anti-Virus Free Edition
Avira Anti-Vir
Avast Home Edition
Microsoft Security Essentials

3. Firewall
A firewall blocks incoming web traffic not requested by the computer user. Firewalls can prevent malware from entering the computer thus fewer viruses and spyware. A great, free firewall program called Comodo can protect your PC and the user can select various security levels for added protection.

4. Windows Defender
Windows Defender is spyware program from Microsoft that is built in to Windows Vista and Windows 7 and as a download for Windows XP, which can be found here. Defender offers protection from spyware, pop-ups, and slow performance. To access Windows Defender, go to Start > Programs > Windows Defender then click the scan button at the top of the window and then remove the threats when complete. Windows Defender is a simple solution to increase computer performance.

5. Encryption
Encryption continues to be a major issue in protecting computer data if it fell into the wrong hands. Many users have huge amounts of information about themselves on their computer including pictures, internet history, email messages, contacts, login usernames and passwords, and much much more. What encryption does is locks the files with a series of numbers and letters making impossible to decode or read for that matter. But the user can read the files with a key and a password which unlocks the files that were encrypted. I recommend using TrueCrypt for encrypting files and works with all versions of Windows.

As for all security software, plan on allowing, at minimum, running all the security programs (anti-virus, firewall, Defender, and more) each week to make sure the computer is protected. It's very easy to secure computers and with a few clicks you even can make it automatic.

If questions arise or need assistance installing or running any of the programs mention above, please feel free to contact me. I will be happy to assist you in any way.
