Some MP3 players sold in the Netherlands have been found to contain malware. The model is "Victory LT-200".
This isn’t the first time gadgets come with viruses already installed (such as Maxtor’s external drive). There have been USB flash drives, camera memory cards, and even GPS navigators that have been sold with infected files pre-installed.
Often it happens when a computer at the factory is infected and somehow the files end up on the device during testing.
Any good anti-virus program would be able to detect the files and clean them for you.
