Windows Vista just got released in a early developer beta the other day and already the first Virus was spotted for the next generation Microsoft Windows OS.

Security company F-Secure reported on their blog that proof-of-concept scripts for the new command console Monad in Windows Vista have been published by an Austrian hacker that show that malicious code can be written. This code samples are in itself not real viruses yet. F-Secure says though that those script holes in Monad could lead to an outbreak of script viruses when Windows Vista is going to be released.
