system restore won’t work, can’t get updates for antivirus software of windows?

June 21, 2009

I believe I encountered a rogue software last week. Received a pop up for a trojan virus. Ran my AVG software and thought I repaired system. Now windows close on their own. I cannot update windows or any antivirus. I have run AVG, Avast, SuperAntiSpyware and yahoo antivirus….nothing is found. I can not do a system restore, nor can I start up in safe mode (F8). I am running Windows XP. Can someone tell me where to turn next

How do I delete virus infected files found on my computer by the Yahoo antivirus protection system?

June 17, 2009

I have the anti-virus protection service provided by Yahoo. It found 3 files infected by the virus when I ran it to scan my computer. However, it does not give me the option to kill the virus or delete the files. The files/viruses are still in my computer. How do I delete the infected files? Do I need to get another (real?) virus protection software or should the Yahoo version be sufficient? Thanks so much!

What happen if I downloaded both a Registry Cleaner, and Avira?

June 3, 2009

I heard that if you download an antivirus program and another antivirus program while the old anitvirus program is still installed, your computer would be all messed up and glitchy. Right Now I have Avira, but Avira doesn't fix the RUNDLL Error, and I look at yahoo answer, nothing work, and youtube too.

So if I download a Registry Cleaner and installed it while Avira is installed, would my computer be messed up? What happen if I download a spyware, malware, registry cleaner, and an antivirus program? What would happen with my computer with all these programs? Since Avira doesn't protect spyware, malware, and doesn't do a registry cleaner.
What would happen if I download with anything in any particular order.
