Google is using a heavily modified (googlized) version of Linux. Since
they are not sharing it with anyone, they don't have to give their patches
back to the main kernel tree.

Apart from that, there are other types of attack that aren't related to
viruses. Distributed denial of service attacks are very popular: a baddie
uses a botnet to attack a site. If one million computers on the net all
simply visit the same webserver in the same millisecond, then it WILL go
down.

Other attacks are dictionary attacks, where an attacker tries to guess the
password for common services like ssh. That can also be done by a botnet.
