My virus definitions have been updated yesterday, and today the Avast Home edition warned me that nvlddmkm.sys would be infected with Win32:Vitro.
I was shocked, because this is a very nasty virus, so i rebooted immediately and let Avast scan my pc on reboot. Only this file seemed to be infected, no other infections found.
So Avast has removed my file, and my Nvidia video driver does not function any more. Next step is downloading the latest NVidia drivers and reinstalling... but now Avast warns me AGAIN for this file thas was unpacked from the driver pack, even before installing it to the system.
Can anyone tell me if this is a false positive? I dare not reinstall the video drivers before i know this for sure.
