Get Safe Online is a little know campaign that's been running for a few years, and aims to be a single source of security information and advice. Most of it seems to be aimed at small businesses which is a good thing.
Get Safe Online Week runs from 12 to 16 November and there will be some online events and webcasts coming out soon i'm sure. http://www.getsafeonline.org/
I'd recommend you take a quick at the "ABC 10 munute guide to security" which is on the front page currently. It states the obvious, but you really should be using Windows XP by now, patching with Windows Update, turning on Windows Firewall and.... securing your wireless networks!!
