i got this today...and I am very suspicious.
since when did Microsoft go around emailing people...surely if there was a big problem it'd be anounced over the internet and spread via 'word of mouth'?...obviously some fool thinking we don't use anitvirus software!
it could also be the "Please do not reply to this message. It was sent from an unmonitored e-mail address and we are unable to respond to any replies." that gives it away, as well as the slightly fake microsoft sign.
people who do this deserve a pat on the back, with a white hot steel bar with big spikes and a kick in the nads.
I delete with the message with satisfaction...
