The best advice if you are using Internet Explorer today is "don't click on any links". Here's a particularly nasty example of how someone can take over your computer if you click the wrong link:

Executive summary: There's a worm that sends an email purporting to be from for example PayPal, claiming that money has been deducted from your account, and asking you to click a link for info. If you are using Internet Explorer, and are not running an updated Windows XP, you will be infected just by accessing that link.
Solution: Mozilla FireFox 1.0, released today. I'll call this an "upgrade" from Internet Explorer. :)
