This is something that I didn't think would happen to me but alas! Now, ZAP stops this, and this doesn't occur when ZAP is on (which is 99.9% of the time) -- and why everyone needs a soft firewall--but when I turn it off to test something, at certain time intervals I get an IE pop up (regardless whether IE was started or running at the time) with porn. Not sure what infected it, but Adaware is UNaware. Norton Anti-Virus is clueless even with the current sig files. Any help would be appreciated.
