I'm getting the same problems, even with Firefox. Initially Firefox was good but now some pop ups get through. I'm also getting a desktop shortcut appearing now too. It directs me to a Zone alarm website. (underhand tactics if you ask me). I run Spybot and Adaware and they don't detect anything. I must have some sort of installer on my pc. Interested in your thoughts.
1. They have only started to appear in the last two weeks, I have had IE7 since it was first available. Have raised "Privacy" on Internet Options to highest level and ,touch wood, it seems to have stopped them.
2. I am using Norton Internet Security 2008, a complete system scan has revealed nothing
No, I used to use an old version IE and got all sorts of pop ups. Then a friend told me about Firefox. I had none for ages. Then I started getting 1 every time I go on line. It appears to be the same advert. The Zone Alarm shortcut is the most annoying.
