This morning, while driving to work, I was thinking of how bluetooth virii spread … basically … how does any computer virus/worm spread … while at it … how do germs and the flu virus spread in humans?

Isn’t it all some basic form of p2p? One infected person/system/phone passes it on to few others, they pass it on to others and so on…

Why not spread the anti-virus software/quarantine/innoculation through the same mechanisms as the virii?

At some level, this would be almost like a common virus, but with a “safe/clean/useful” payload instead of something that causes hard drive crashes, etc.
Also, this can be controlled easily … where the “anti-virus payload” is recognized by whatever Anti-Virus software is installed and used as an update/patch.
