There was somethin on my comp which I thought was a prog I dl. Iclicked nothing happened...ran adware got 393 objects...cleaned them all out...but it installed somethin into my program files called istsvc. It runs in the background and will not leave. If I shut it down...and run adware then I get rid of all traces...once I restart it all comes back. I use 3 diff spyware programs and nothin stops it from coming back...any suggestions?
