It is a malware. Not sure what you have...but you need to run what programs you have, then retart yourt Pc and run them again...likely a bunch of times. As well, make sure to try a few different programs, like Ad-Aware and so on...but also...add and delete those programs and make sure they aren`t all running at the same time. That can create conflict too.

Try to get the name of it (the virus) and google it for info....look for exe. files, but also anything related to it that your scanners might find.
