Apple Computer Inc. has warned Windows users that a very small number of its latest video iPods have a virus. Less than 1% of the devices are affected.
Just 25 reports concerning the problem have been received by Apple so far. The virus does not affect data on infected PCs.
Apple's technical support Web site warns: "We recently discovered that a small number -- less than 1 percent -- of the video iPods available for purchase after September 12 left our 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," company vice president Greg Joswiak told Macworld UK Tuesday night.
Joswiak explained how the virus infected the iPods: "As you're probably aware, the majority of iPod sales are made to Windows users, so we have some Windows terminals on our production line," he explained.
"We discovered that one of these computers was propagating this virus, fortunately less than 1% of video iPods were exposed to this Windows virus. The problem has been corrected, and all the video iPods we are now selling are free of the virus," he said.
The Windows machine that did the damage is used as "a final test station" in the quality control process, Joswiak explained.
"It appears this virus propagates to a PC when an iPod containing the virus is double-clicked in Windows Explorer. Technically it's a worm. It does not spread through a network."
Asked whether this implied that someone at the production center had infected the machine, Joswiak said, "We're not getting into details. There was an exception in the process that we have now remedied.
"We believe we have a process to make sure this doesn't happen again," he added.
"It's the first time this has happened to us, and we wanted to be very open and upfront about what's happening. We first learned of this a week ago," he added. "Since then we have been working around the clock on this, discovering the root cause."
"We understand that this virus/worm doesn't do any data damage to the Windows machine, but that it can lower the security settings of an infected PC," he explained. "It should be removed from any infected machine."
The virus propagates itself using mass storage devices. It affects only Windows computers. Up-to-date antivirus software "which is included with most Windows computers should detect and remove it," the company explained.
"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," Joswiak said.
If any affected users lack antivirus software, Apple posted links that will allow them to download trial versions of antivirus software packages that detect and destroy the worm.
After installing an antivirus application, users should attach their iPods to their Windows computer and run the antivirus program. Affected systems will trigger an alert, and the antivirus software will quarantine or remove the malware. Users should then run the Restore function in iTunes 7 to restore the software on the affected iPod.
Because it is a mass storage virus, users are also advised to scan all their existing external storage, including but not limited to, hard drives, digital camera memory cards and flash drives, to see if they have the virus.
Apple isn't the only MP3 player manufacturer to have been hit by a virus. Fast food vendor McDonald's Corp. last week had to tell 10,000 of its customers that thousands of MP3 players given away in Japan as part of a special promotion had been infected by a different virus.
The McDonald's virus (the WORM_QQPASS.ADH) could apparently infect PCs and steal personal data.
