I googled that message. It's something to do with IE and Vista.  According to all sites that I browsed it's probably an add-on program for IE that is causing the problem. The solution is to  try disabling all the add-ons in IE  (Try running IE in "no add-ons" mode.)

Go to Tools - Manage Add Ons -Enable or Disable Add Ons. Change the Drop down to Add Ons currently loaded in Internet Explorer

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
