I am running Vista on a Dell 1525.
I updated my Avast software and immediately received a warning that my computer was infected with Malware Win 32 rootkit-gen [RTK]. I ran Avast and it seems to have removed the virus. In the process of removing the virus it damaged something related to the "Sigma Tel High Definition Audio CODEC" and I currently have no sound.
I tried downloading a new driver for the Sigma Audio and received the same malware warning that the downloaded file is infected with Malware Win 32 rootkit-gen [RTK].
My question is, could this be a false positive I should ignore, or could the drivers on Dell's website actually contain the virus?
