Format windows partition and delete all executables on all other partitions on internal and external storage devices that had writing access.
Last time a roommate of mine reported his computer behaving odd and after checking and finding malware I recommend reinstalling Windows. I forgot to mention he shouldn't reinstall his applications from backed up installer executables and so he promptly reinfected his fresh windows again. Bah. He gave up and ran his computer infected, obviously I avoided any software that he tried to give me on USB keys like a plague.
Don't advertise that you got infected and did not do a proper sanitation of your (build?) environment. You aren't making me confident your software on your web properties are safe, there are enough scary stories on the internet with compromised upsteam. This paragraph will self destruct in a few hours.
