Hi, Norton alerted me to a new virus called backdoor.tidserv!inf a few days ago, but can't do anything to clean or remove it. At the same time the sound on my computer stopped working when I play dvds, youtube/hulu videos, or even pandora. I reinstalled all the drivers so the virus must be interrupting it. Malwarebytes finds no threats, and avast doesn't seem to have helped. Anyone have any ideas?
