Safe Personal Computing.
Bruce Schneier, has a new article on his blog in which he gives home users concrete actions they could take to improve security. As the holidays come and I make the rounds to disinfect and repair all my family's computers, I'll be printing this out and sticking copies to their monitors.
I bet I'm not the only one who is called upon for tech support at the inlaw's on Christmas morning. The suggestions in his article are excellent. Additionally, I have a USB thumbdrive, before I visit a relative's house where I expect to make a support call I make sure I have loaded: Spybot, Stinger, Ad-Aware, Firefox, AVG, and the Zone Alarm firewall. All of these are free for personal use. I hide IE and set Firefox for default. I make sure Automatic Updates are enabled. If they have broadband, I take them to the store and buy the cheapest NAT router available.
