IM Worm on the spread??

Looks like there is another IM worm on the loose (similar to KELVIR).  For those of you who are using IM, please do NOT click on any random links sent to you in an IM conversation!

Good news?  For those of us running Communicator in a Live Communication Server 2005 SP1 environment which is using the IM Filter, you are safe from this worm.
