that's not to say it isn't a problem, because zombies Suck.

People with access to the ppp, dhcp or nat logs for a network can de-dup the counts based on IP addresses to come up with better surveys of infected computers. They can further correlate the reports with contact
with the computer owners of how many computers were found with known or unknown malware. But we rarely hear data from them.

Although I disagree with some of the survey counts, finding zombies isn't a problem. Figuring out if a computer is actually fixed and stays fixed is still the problem. Sometimes it feels like an episode of "House." Except House wraps up the case in 60 minutes.
