Last night I figured out I had a virus, so I was running scans and everything. I deceded to install more anti-virus/spyware etc, so I downloaded them, installed them, and restarted. When I restarted it went to the "windows is starting up" screen and then 10-20min later it went to the "welcome" screen and doesnt go anywhere from there. Right now I am in safe mode scanning everything. Is there any way to fix this? and what about the possibility of one of my scanners deleting a critical system file? Any help will be greatly appreciated.
