Once when another person in IT was on vacation, I was handed off a manager's laptop to scan for porn. There was no automated tool, so as I recall I did a search for files created or modified since the last check. I found nothing to report. I think that the periodic checks were set up because a subordinate of the manager's had seen the porn on the machine, and had gone to HR.
