One of my users is having an issue with their machine which I have not been able to solve over the past 24 hours. Even after running avg av, avg antispam, adaware, spybot, spyware term, it cleans some things out (one of which was the task manager greyed out and unavailable trojan.) But we still get this audio playing randomly. It sounds like some politcal propoganda from a foreign country, maybe korea, and cheering, and an engine running. Then, sometimes the browswer redirects to yahoo / hotjobs. And of course, freezes and becomes unresponsive. Any help would be appreciated. This is one of the first trojans I have not been able to figure out on my own. Thanks for your time. The machine is xp sp2, fully updated, updated avg pro 8 in a clean corporate environment.
