When you examined a computer did you use Sysinternal tools (TCPView and
Process Explorer) at http://www.sysinternals.com/ntw2k/utilities.shtml

Usually when a computer is exhibiting strange behavior one of those two
tools will help you identify unusual programs running.

The most common way that a computer is breached is either a) weak or blank
passwords or b) machine was not kept up to date.
