I have an HP desktop with XP SP3 and I use Firefox for a browser; recently I noticed the computer running slow and I find IE7 running two windows in the background (found using Process Explorer, doesn't show up under Applications on Task Manager). I never see any window of any kind from IE but one of the windows uses a huge amount of resources. I can kill the processes and the computer runs fine, for a while, but then the processes (both IE instances) come back, without anything appearing on the screen. I have read and tried some other methods on this forum, but have been so far unsuccessful. Here is a log file from Hijack This.

Thank you in advance for any help you might be able to offer.
