Where to begin? My computer began randomly playing simultaneous audio streams of random ads through the speakers. It is not consistent; it is not even decipherable. Initially, we ran Norton, then MBAM, Ad-Aware, then Comcast's security suite. Finally, the computer was taken to a previous system restore point. All to no avail, obviously. Then I did my research and used Kaspersky's TDSS rootkit and rkill. Neither of them found a thing: nada! Through trial and error, all I know is that this bug does not activate in Safe Mode and will not sound off without access to the internet. Does any one have any insight at all?
