I just cleaned one off my daughter's PC, forget what it was called, but if
it's the same one, it give options of Emoticons, pretty pictures at the top
of your we-page etc.
This also had no uninstall.
I ran Spybot which identified lots of 'nasties' but most importantly, gave
me the program's name.
Quarantined all the bits Spybot found, did a full Regedit search for all
instances of the program name and deleted the lot, then finally deleted the
program folder from Program Files in Explorer.
Clean as a whistle now.
Try that, but backup your registry first if you're not sure what your doing.
