Two guys can’t do it alone
I visited a new customer today that set the record for the most viruses and spyware on a single system. The computer had no anti-virus program of any sort on it, no anti-spyware system, was running the first version of XP, and on dial-up. Needless to say, the computer was hosed and it took more than six hours to clean-up (between what I did in two hours, and the four hours I let the user take care of in secondary scans and cleanup).
The customer made a comment that I hear often in this situation, "This kind of thing makes work for you, huh?." My standard answer, "Yes, but it is the worst part of my job. Why? Because this is so preventable."
