The other thing to be aware of if you are suspecting spyware/rootkit
activity, is to close everything on your system and for 24 hours do an
ethereal capture on your machine. With the newest covert channels that are
being used it wouldn't be surprising to see basic one-way communication
occuring (i.e. at 3:00 am when you are sleeping, your computer is sending
requests to google.com, with the source address faked, Google.com is going
to replay the response to the attackers machine). It will be obvious to
you though what is occuring.
