Skype Worm targets other popular IM clients

According to the Spyware Guide, a Skype worm is in the wild that not only targets your Skype contacts, it also checks the registry for programs like AIM, Trillian, Yahoo Messenger, Miranda and  ICQ and then attempts to send the infection via these other IM/VoIP clients. According to the Spyware Guide, "it uses the tried and tested methods employed by similar infections over the past few months, with the ultimate payload being the Stration Worm." This "cross-breed" worm that goes across multiple popular IM networks is certainly an alarming trend. I should point out that now that Skype features "pay by Skype" (Paypal integration), this gives virus/trojan writers yet another area to target to try and surreptitiously steal funds from their victims.
