I have already run XoftSpy, Spyware Doctor, Registry Mechanic, Norton, and NoAdware.
None of these have worked, what exactly happens is:
When I open IE it gives me my homepage, then if i try to visit any site, not just a Search Engine, it pulls up an ad, Sweepstakes.com. It closes the site I am trying to visit and does not let me go anywhere.
PLEASE HELP!
