Basically, if you get a message in your Inbox from one of your friends/contacts, saying something along the lines of "look at this funny video of you", then DO NOT click the link, as it's not a funny video, but a malicious virus download, or a website of some sort - called Koobface.
I haven't seen it, but I'm assuming the URL probably looks dodgy anyway, so I never give anything like that a second glance, but for the less technically savvy, who would naturally assume that it is legitimate because it's from someone they know - WATCH OUT!
I Think it's better to post your own profile link so people know they've got the right person like I've done Below...As Searched for Dean Atkinson for example and there's a few from West Midlands with the same name.
im on face book too, was asked by the radio ppl to set up a fb group for bugle boy lol.
I put it up yesterday, its called 'Sky Blues Bugle Boy', feel free to join and aslo add me as a friend.
