Fauxvirus/Carny Ride.exe

When I do a quick scan, NIS hangs forever on a file named c:/fauxvirus/carny ride.exe.  I can't find this folder of file anywhere on my hard drive.  I noticed discussion about 2 years ago on various discussion boards, but no definitive answer.  My computer seems to be running extremely slow, and I'm having a problem downloading my email. I don't know if all these problems are related.
