Apparently there's a virus about (who'd have thunk it huh?)
My brother got a video e mail sent to him by a friend of mine via facebook.
As it was from a trusted source, he opened it and was hit with a virus.
Apparently this thing hooks on to your facebook and sends the e mail to all the people on your friends list.
In turn, your friends openthe e mail and it's sent to their friends.
Be extra cautions of vid e mails EVEN if they are from a trusted source.
