Assuming you're running a Windows box, the virus may have disabled your anti-virus program. Restart your computer in Safe Mode with Networking, download a brand-new anti-virus program (I like http://free.avg.com/ca-en/homepage]AVG Free), install it, and run a full system scan. This will take a while, but it'll find almost anything on your system that shouldn't be there.
(Alternately, if you have access to a second computer, use the second computer to download the anti-virus program and burn it to a disk, restart your computer in Safe Mode, install the AV software from that disk, and let it run. That's even better, but it does require a second computer...)

them. Adversaries remain citizens of the same state, common subjects of
the same sovereign, servants of the same law."
