Unfortunately, because all our virus checking thingies are out of date the pooter froze about 10 minutes later, and I was unable to write my triumphant 'hurrah it's working!' post from home as I had planned (complete with cheesetastic picture of me sitting at the PC, grinning). So instead I'm writing this from work while our systems are broken.*
Still, at least we're able to get on t'interweb to pick up viruses, which is definitely progress.
*I'm starting to think I have a strangely powerful magnetic field surrounding me, that has the ability to break electrical equipment from 20 paces.
