Did you disconnect from the internet and reboot in safe mode when you ran your anti-spyware? If not, do it. Some trojans hide out in areas of the system that are protected when the computer is in normal mode.

Once all of your scans are done and you've gotten rid of the infections found, reboot in normal mode and connect to the internet. Then see if you get the same message when you run IE.
