I moved this to Malware Discussions. You mean servieca.vbs? McAfee should remove that, if not then try Stinger and perhaps Malwarebytes Free, both in the last link in my signature below. To keep Malwarebytes free don't accept the free trial offer.
It's an autorun worm. The danger lies in the fact that it contacts a remote server and attempts to download other malware.
McAfee should detect and remove it - see the instructions in the third link above.
