A sinister new worm, which appears to have originated in France, is targeting mp3 music files.
The W32/Nopir-B worm spreads via peer-to-peer file-sharing systems posing as a utility that makes copies of DVDs. Once on a user's machine, it displays an anti-piracy graphic and attempts to delete all mp3 files
and disable various system utilities.
The worm is not yet widespread, but experts are urging users to ensure their anti-virus software is up to date.
