Electronics giant Apple has warned that a batch of its Video iPods have been infected with a software virus.
But it said that less than 1 per cent of the devices on sale after September 12 were affected.
Apple received around 25 reports about the RavMonE.exe virus but could not confirm how many had been shipped to the UK.
Apple said that up-to-date anti-virus protection should detect the malicious program and stop it causing problems.
Only affects Windows
The virus spreads via mass-storage devices such as external hard drives, digital cameras with removable media and USB flash drives.
The virus only affects Windows computers and the iPod Nano, iPod Shuffle and Mac OS X are not affected.
A selection of free anti-virus programs is available through the Apple website and the company is advising owners of Video iPods thought to be infected to install the anti-virus software.
After installing the software attach their Video iPods to Windows computers and run the programme.
Apple also recommends that users scan any mass-storage devices that they’ve recently attached to their Windows computer.
A statement on the Apple website said: ‘All Video iPods now shipping are virus-free. As you might imagine, we are upset at Windows for not being more hardy against such viruses, and even more upset with ourselves for not catching it.’
