I recently hit, by mistake, what I thought was an Explorer upgrade option.  It turned out to be a pop-up appearing legitimate but really was not. It uploaded a product called Intelligent Explorer on my machine.  What a nightmare!

I did some research on the web and found messages like this one from a BullGuard Antivirus Forum,

"PLEASE HELP!!!  I HAVE A SPYWARE, TROJAN AND HIJACKER ON MY COMPUTER.  I HAVE RUN BULLGUARD, CWSHREDDER AND AD-AWARE.  ALL HAVE PICKED UP THE VIRUSES AND SAID THAT THEY HAVE BEEN MOVED/REMOVED BUT WHEN I LOG ONTO THE INTERNET THAT DAMN INTELLIGENT EXPLORER TOOLBAR IS SHOWING"

Another message from spywareinfo Forum goes something like this:

"Hey I'm having issues with something called Internet explorer toolbar - Intelligent explorer. I can’t find a way to remove it from my comp and I really don’t want to reinstall windows. I've used spybot, ad-ware, and cw shredder but nothing seems to work."
