Hi guys, Last Sun or Mon I recieved a "you have malware warning" from Avast. I have Avast anti virus, spyblaster, spybot search and destroy and spyware doctor. and malwarebytes. I have run all of these several times and it appears that I have finally removed all of the crap that was on here. I have run Registry Mechanic and jv16 PowerTools. Only I think whatever trojan I had has actually started deleting the good file as well as the bad. I now have no sound. I have tried reloading the drivers but doesn't want to know. this PC is only 3 months old. quad core processor, Realtek HD Audio drivers
