|'I've run my McAfee over my system and it says there are no problems'|
There are many better scanners than McAfee like malwarebytes, trojan remover,hitman pro and the lsit goes on.
One scan is never enough when it comes to removing different problems.
If you google for something and you can't find it...chances are it's another new variant of some kind of spyware, adware or virus.
Some HELP in posting on Computing.net plus free progs and instructions Cheers
