OneCare Beta has just been allowed ‘live’ to people outside of the USA. I highly recommend trying it out, it includes AntiVirus, AntiSpam, Firewall as well as a few other additions. Pop along to here and try it out.

Second attempt - Are you sure this is available? The site still says “At this time, participation in the Windows OneCare Live beta is open to U.S. residents only”.
