Q: What's on your laptop? A: Malware.
Friends often ask me what they should do when their computer is infected with the virus du jour, and my response always takes the form of a question: "Is your data backed up?" If the answer is "yes", then I advise reinstalling Windoze (XP, 2K, whatever...) and then restoring personal data from the backup. If the answer is "no" then I usually respond, "Give up and get a Mac!".
Now that second response is pretty glib, but there is a reason and don't think for a second that Macs aren't susceptible to malware. They are, but with most hackers focused on Windoze, there are far fewer attacks on Mac OS. More importantly though, with a good backups, a virus, worm, or rootkit is an annoyance, not a catastrophe, and Macs make backups easier by centralizing all of your data. With Windoze, the data you need to capture is all over the system.
So cut a CD, compress to an external drive, put it all on a USB keychain, whatever... just get it done, because in these uncertain times loss of one's data is tantamount to plagues of locusts and rivers running red with blood.
