"Hijack This" saves the day! Okay, so I'm surfing, looking for a picture of Nina Hagen (in one of her more aggressive attitudes). Suddenly, wierd things start happening. Gazillions of popups all over the place. My "Zone Alarm" goes nuts. Several programs I've never seen before are trying to get out to the Internet. Sure 'nuff, I look in my registry in the HKLM...\Run and I see new stuff that wasn't there before. Oh oh. I clean everything up, delete the files that are being referenced, and reset my IE security to "high". I'm pretty sure I have everything fixed. But NO! Every five or ten browser flips, I get a popup ad. It looks legit, like University of Phoenix and that kind of stuff. But still, I'm worried. I immediately run "Hijack This" to see what I may have missed. Oh boy. There are 14 entries I can't account for. 13 of them are dated today. Anyway, to make a long story short, "Hijack This" is a wonderful thing. My question is, how can I keep this browser hijacking stuff from happening in the first place? Will an ordinary popup blocker stop it? Is there any way to tell when someone's trying to download a .exe into my machine?
