Yup, if you're machine has been infected by a Sony music CD, then you're in a big trouble, viruses are now using the rootkit (commonly used by "hackers" to attack a computer) that the Sony music discs install on your system in secret to hide themselves from anti-virus software.

This is what the Sony BMG' president had to say about it "most people, I think, don't even know what a rootkit is, so why should they care about it?". They will care about it when they've realised it's destroyed their machines.

Basically the virus is invisible because it's hiding within Sony's rootkit and you're screwed. You may send the bill for recoverying data and restoring the machine to Sony, and you can also join the lawsuits that has been launched against them.

Or you could just boycott Sony, I don't own any Sony products I stopped using them after their proprietary memory stick format, their proprietary minidisk format, their proprietary UMD format, their proprietary Blu-ray format, their proprietary DVD+RW formats, their proprietary ATRAC formats and you get the general idea.

It reminds me about a chat I had with some woman when she revealed she was after a PSP but was furious about the lack of stock (we've had like 10 in the last 2 months), and I said to boycott Sony - she said you can't avoid them. Well I'm avoiding them quite well, as it most other people I know.
