There are a couple of new worms on the block; one aimed at MySpace and the other at facebook.

I doubt if anyone here would get caught, but I am sure that we all have relatives, friends, customers and co-workers who might?

You will need to check your AV to see if they are covered (details here):

Two variants of the same new worm, Networm.Win32.Koobface.a (the MySpace muncher) and Networm.Win32.Koobface.b (the Facebook fancier) have been detected in the wild by researchers at security vendor Kaspersky Lab.

So, if you get a message along the lines of "Britney indicted for lewd act with bisexual gopher" it probably isn't what it says
