for those who got hit by this last night .. if you still have it you can get rid of it by uninstalling msn , killing all the msnmsg.exe's running "or ones of the like"
then running a spyware scan "ad aware or something of the like "
that should get rid of the .dll's that are fucking your shit up .. there are also some .exe's in your c:\ and windows folder that you may have to get rid of yourself ..(anti virus software should do the job tho )
ICQ me if you need help 339-139-976
