A friend told me it stands for Viruses, Infections, Spyware Threats and Adware 🙂
Well, seems he was right!
The first viruses for Vista are out and M$ is denying them as usual.
The proof-of-concept viruses use a vulnerability in the new Windows Shell, called Microsoft Shell (MSH). It was codenamed, weirdly, Monad.
EDIT: Microsoft Shell:Monad::GNU Shell:Gonad?
Microsoft’s answer to this challenge was not to fix the problem. Instead, Bill’s engineers have pulled the whole feature from the OS!
