I have AVG Free Edition. Lately it's been alerting me that a virus was found in the following files: msxp.exe, SYS98.exe, and SearchB.exe. I know that when my computer was infected with a virus in the past, this "SearchB" folder thing keeps appearing on my desktop, and after repeated attempts to delete it from the recycle bin, it keeps popping up. Thing is, I can't find it on my add/remove programs list, and I can't find these other files to remove them, as well. Every time I reboot my computer, AVG alerts me to the viruses and i click "Heal" and it always says "Object Successfully Healed".
What's going on here?
