This morning, during a full scan, Avast! detected a virus, threat level: high, and moved it to the chest. The file name was C:\Windows\system32\drivers\mbamswissarmy.sys. In addition to Avast! Internet Security, I have Malwarebytes Pro Anti-Malware. They usually play nice with each other, so I am curious about why Avast! might have perceived this file, which seems to be associated with MBAM Pro, as a threat. Also, MBAM has recently detected and removed threats that seemed, based on their file names, to be associated with Avast!. None of these removals seem to have affected the performance of either security program, so I will leave it in the chest until I figure out what's going on. Can someone please explain this?
