I'm back with a pop up problem on another computer. This computer seems to get excessive popups whether your using the web browser or not. Things like video sites, media sites, colleges, healthcare, and dating sites. The only lead I've seen was a link to 'buycheapadvertising.com' in one of hte sites privacy statements. I've now put hours and hours trying to track down the problem, but nothing seems to affect it. I've used all of the following programs which scanned (and found at least something) and deleted, but the problem persists: [all up-to-date] Ad-aware 2007, Spybot S&D, AVG Internet Security, Spywareblaster, Ewido, Malwarebytes, Vundofix, and McAfee. Attached is my HijackThis log. Any help is appreciated!
