Our eighth Q & A of the week comes from Ahmed via the PCstats reader feedback page . If you have a question you need answered right away, try our friendly forums for help too.

Q: Whenever I connect to the Internet, there are about 4 or 5 culprits who install their programs. They may be spyware or other program which even break the registry. I run spybot s&d + antivirus every time. Anyone of them has installed 3 files as following: ied s7 c3.exe Download.Trojan. these files could neither be deleted nor quarantined by the Spyboat and Antivirus. I am very much worried as my computer P-3 is running very slow. What to do?

A: The first thing you should do is ensure you have the latest virus definitions for your antivirus software, download Microsoft's anti-spyware software and update it too, then reboot your computer in safe mode (using F8 at startup). From safe mode run both your antivirus software and the Microsoft Anti-Spyware program.
