I hope that someone will be able to help me out here... Please tell me if I'm leaving out any important information.

I recently had a hardware malfunction with my hard drive, and I lost almost 3 years worth of information. After purchasing a new HD, I used my gateway recovery disc to reinstall windows XP. I immediately downloaded Mozilla Firefox. I haven't visited any disreputable websites. I get all of my software from download.com, and I visit a few movie websites, toy collecting websites, etc... All sites that I have visited for years. Yet, for whatever reason, I keep getting pop-up advertisements from Internet Explorer. I'm not even using IE as my default browser. They come maybe three or four at a time. I left my computer signed online overnight after I first reinstalled, and I had almost a hundred and fifty pop-ups on the screen in the morning, according to the tab in the task bar, anyway. I've followed almost all of the steps here;.

If someone could please help me out with this log, I'll really appreciate it. I had a similar problem when I first got my computer. I've been using this computer for almost 3 years with no problem.
