I use Avast! antivirus - not the highest rated, but works for me with other protection tools (Malwarebytes Pro, Hitman Pro, Privacy Eraser Pro). But I don't seem to have much luck with "deep cleaning" tools. They always clean too much and I end up restoring from a backup image. Think I'll wait for other's reviews on this. If anyone can make this type of utility that satisfies me, it would probably be Avast!
