Just fix a laptop with similar problem load up and FBI message pop up to pay a fee so laptop can be usable, to repair it; burn hirens boot cd it's a free download, boot up from cd and run mini windows xp, then run the malware software or a ccleaner it provides and you should be able to get rid of it, by the way after you boot up does a message pop up asking to run a program?? Might be the last download you did.
