And of limited real value. A CPU only miner would yield about 10 MHash/s or less on standard hardware, and a malware/junkware loaded PC will do even less.

I recently came across a very naive-looking sample of a pooled GPU-miner being distributed via a purported crack for a certain EA game.

It's ridiculously easy to implement GPU mining if you have any remote execution on a machine.

Isn't the total hash rate the sum of the hash rates of all infected machines (i.e: 10MH/s * 2000 infected machines = 20GH/s)?

Far less than that. My shiny quad core i7 gets 4MH, and I doubt most consumer desktop computers would manage that. You're probably looking at 0.5-2 at a maximum.
