Worm Spreading Through Skype IM

I use Skype...occasionally. I did pay for the Skype Unlimited service, and I like being able to make calls from my laptop and use my bluetooth headset for hands-free talking. But, I haven't had many opportunities lately to use it. One thing I have never used though is the instant messaging feature that lets you chat with other Skype members. So, I was a little surprised to find a box pop up on my screen attempting to initiate an instant messaging chat session over Skype recently. I just clicked the 'X' and closed the box. I don't accept any links or invitations, suspicious or otherwise, from people I don't know on the Internet. It turns out, that was a wise move on my part. Had I clicked on the link to accept the incoming chat session, I probably would have been hit with the Pykspa.d (a.k.a. Ramex.a) worm.
