All the computers I ever took home from work had something dodgy on them at one time or the other that I wouldn't want IT to find. The best I could do was to keep a low profile so IT wouldn't have to dig deep other than a quick scan and delete.
Of course one could always accidently lose the computer.
I saw a high level manager get a new career assignment once when his computer froze up and IT had to dig deep to find the problem.
In this day and age I would opt to have two computers in my travels . One for work and one for my own use.
