VIRUS WARNING

Think most people have heard about this by now but just in case: there's a nice new virus doing the rounds - there is a description involving lots of technical gubbins like "worm" and "open ports" which if I try to remember I will get horribly hirribly wrong, but luckily it can be found in a far more coherent form here

In particular it exploits a weakness in Windows XP and NT. A patch is available and a link to it can be found here
