There are two more methods I use.

1. IEFIX

Type that into http://www.google.com Well explained.

2. IERADICATOR

Again, it's on a google. But in that usage I install Firefox, the run IERADICATOR and then goto Microsoft and install IE 6 again. Then Windows Update.

3. http://www.doxdesk.com/parasite/

If you had the PREVIEW pane open, then pests have their ways with the machine. Tools are listed to find and eject them.
