IEXPLORER is consuming most of my resources

Running IE ver 6 on XP SP2, I noticed that it is consuming around 70% of my CPU resources. I can see the task is running, but it doesn?t open the browser. I ran Kaspersky AV on Safe Mode, but still cannot find any virus/Trojan/spyware. I was following the threads but I did not find anything suspicious. The weird part is that when I login as administrator or any other user on the same PC, it is working fine, which confirms that it is some add-in to the IE. Ah!! I tried to uninstall IE and reinstall it and it didn?t work. Any ideas guys? Thanks
