D'oh! Who let the Windows virus into the iPod factory? Apple Computer said today that a tiny number of video iPods that shipped after Sept. 12 contained a Windows virus named RavMonE.exe.

On its technical support page, Apple said it has received fewer than 25 reports of the problem. Still, the company takes the opportunity to get a little dig in at Microsoft:

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.

The virus affects only Windows PCs and current anti-virus software should get rid of it, Apple said.
