I would recommend downloading anti-malwarebytes from
http://download.cnet.com/Malwarebytes-Anti-Malware/3000-8022_4-10804572.html
It is free and usually can clean up this type of stuff. Had this issue with a co-workers computer and this cleaned it up. Took awhile to launch it after downloading as the virus did not want to allow it, but when we launched right after startup it worked fine and cleaned out the malware
Ditto on malwarebytes. Also, create a new user which is an administrater and log in under that name, then download and run malwarebytes.
