Patch your computers

Tomorrow is the first day of spring. This is a good time for spring cleaning — patch all your computers and your applications, make sure your firewalls are up, your WiFi networks password protected, etc. As John Markoff writes in a recent New York Times article (subscription required), a major botnet worm called Conficker might be released on April first, and you want your computer to be safe. After all, you will need it that day to enjoy all the April fool’s pranks.
