Spybot S&D found two instances of opachki.ru on my PC last night, and I'm having trouble getting rid of it. Initially I had problems because it said I wasn't an administrator and couldn't remove either instance.

Having run S&D as an administrator, it has now removed one instance of it, but can't delete the remaining one as it says it may still be in use and running.

Has anyone got any pointers at how I might remove this? I saw a manual solution somewhere which started by suggesting I delete certain files and registry keys, but I must confess I didn't really fully understand what I needed to do, and therefore didn't want to make any blunders that might exacerbate the problem.

Help!
