The Security Mentor

Now it's not safe to plug a music player into your computer. I just ran across a viruslist.com article about virus infections in iRiver and Denver MP3 players. The author, Roel of Kaspersky Antivirus, suggests reformatting the devices before you use them. OK, if you don't mind the hassle, if you don't mind the risk of erasing something you'll need, and if you're sure that the virus infection isn't in some area that survives when you reformat the device.

All I can think of is to have antivirus software that's been updated more recently than your MP3 player was built.
