A pop up window titled - ULWindow Seek keeps popping up on my pc screen, even when I am offline & tries to open a webpage. When I am online, I have found that it has originated from the site Search::Control. I am using Spybot Search & Destroy 1.4 in my pc besides Norton 2005, which I keep updated with the latest virus definitions. Besides running Spybot, I have deleted all the cookies of this website manually, but the pop up window has still not been disabled. Can anyone please help ?
