Sounds like you were hacked. Same happened to me.
There's a few things you need to do. First check your
antivirus for any files and folders that have been added
to the "exclusion" list for both manual and automatic
scans. The error is from a program called flingstone's
bridge (spyware) the dll has been deleted but the program
is still there. download spybot s&d to find and delete
any spyware/adware. if spybot doesnt find it you can
download Bazooka. This is an adware/spyware scanner and
shows you how to manually delete problems. Next step run
windows update and install all critical updates. Finally
open your browser and click: Tools > internet options >
Programs > hit the "reset web settings" button. Ive
provided links below for Spybot and Bazooka. Both are
freeware. Hope this helps and good luck.
