Subject: AW: AMDPatchB & InstallStub

Best practices always dictate a rebuild when a machine has been
compromised.  And there's good reason for those best practices.  You NEVER
know what might have been left behind.  The only way to make sure that all
the nastiness was removed (how easily can you detect a remote control
trojan that only passively monitors inbound icmp packets for command and
control, but never opens and tcp or udp ports and is clever in hiding
itself in the task list?).

Not to sound like the paranoid security person that I know that I am, but
it really is a good idea.  Heck, even microsoft knows it's the best
response even when it's only a worm, let alone a manual compromise:
