try re-booting and then while booting tap "f8" the keys on the top. When a menu appears, try to boot into safemode. Once in safe mode with networking you can download a anti virus or ccleaner to try to clean your laptop and restore it. Checking system restore could also help. As you might be able to restore to a earlier point.
