Oh...and as for AV - Best AV hands down is McAfee Enterprise AVD

Kaspersky is crap, ive tested it downloading known viruses and it didnt spot them

It's also good to have your windows installation on its own hard disk. Then you can re-install with little effort. Save all your music and movies on a seperate physical disk and re-map your my docs by right clicking on the icon and pointing it at another drive

Plus, if your windows goes nuts and starts blue screening you dont have to fuck about retreiving data from it before a reinstall
