My avg ran a scan on my laptop with Vista installed. It said I have a trojan horse called BHO.MEU windows\system32\PeNx-1t_C.dll I tried to remove it and it said forced removal would cause the computer to crash. It was moved into a virus vault but I am still uneasy knowing it is there. Is there a safe way to remove it and how could I have gotten it? Thanks,
Google the name of the virus and any associated filenames. You'll probably find a recommendation on how to get rid of it. If you keep getting attacks then there's probably something still resident on your machine (not just in the vault).
