In the hope that at least one person I know will be wiser to it, there is a new email-borne virus that pretends to be a Microsoft security patch.
More info here.
Just a reminder — if you are not expecting an attachment, even from someone you know, DON’T OPEN IT. It’s the best security measure that you can take to avoid getting infected.
And to all of those who think it’s cool to send jokes as attachments, DON’T DO IT, because then when you get hit by a virus (as you probably will given you are opening attachments) and it gets sent to your friends, they’ll think it’s ok to open the attachment.
If you can afford it, get anti-virus software, just don’t install the McAfee Internet Security package – it kills computers and is worse than the viruses it claims to protect you from.
