From the name I guess it came from some video/audio codec package (or at least that's where it was first found by the virus scanning companies, it may well have ended up on your PC via some other route).

Has it really killed you HDD? Assuming you might want to save some stuff that's on your existing HDD (or if it's dead, or even if not - HDDs are getting larger all the time and are pretty cheap compared with a new PC), I'd be tempted to just buy a new HDD and re-install some operating system (Windows if that's what you're used to and you still have the installation disks, or Ubuntu Linux if you're not bothered and just want something that works and is free.)

Anyway sorry to hear the bad news and hope you're up and running again soon.
