Try an online scan and removal from Trendmicro.

http://housecall.trendmicro.com

It scans and removes viruses through your web browser.
Go to system restore .....to a date that you know your comp was not infected and restore it.
If you are windows go to their download site and get their Maware removal tool. run it. The go to spybot search and destroy from safernetworking.
try NOD 32..it is a better antivirus.....
