A rather industrious piece of malware that - among other things - paves the way for other malware by disabling AV solutions and software update modules has been spotted spreading via several Instant Messaging applications (ICQ, Skype, GTalk, Pidgin, MSN, YIM) and Facebook.

The victims receive a message from an unknown user, offering a link to a funny or interesting video. If they follow it, the malware in question downloads automatically from the linked site and is executed.
