I recently posted the same error msg while using Fast User Switching with XP.
This problem could be caused by either Google tool bar, or Add-ons to IE,
and these need to be dis-abled.

Go to View > Toolbar > and then un-check Google Toolbar. Close out of IE
and reboot the computer, and you should be able to re-launch IE normally.

If that doesn't work try the following:

Goto Tools > Internet Options > Programs > Manage Add-ons. You will see a
list of add-on services\files that are running within IE. You will need to
review and selectively dis-able those add-ons that are not needed. It's hunt
and peck time, and you may need to dis-able all of the add-ons and then
re-enable one at a time. Be careful.
