A smaller percentage of video iPods from Apple Computer have been shipped with a virus affecting Microsoft Windows, the computer maker said.

The Cupertino Calif.-based firm said video iPods available for purchase after September 12, 2006, left its contract manufacturer carrying the Windows RavMonE.exe virus.

The iPod nano, iPod shuffle and Mac OS X are not affected, and all Video iPods now shipping are virus free, according to a statement on Apple's website.

Less than 1 percent of video iPods shipped carry the virus. Users are recommended to run anti-virus software on their machines after the first use of the video iPod.
