By all means, fool around.
I'd appreciate it if you didn't fool around too much, though, this can be a fairly serious business. Especially in this sub-forum, where people who are infected often come for help.
Serious infections can cost people a lot of money.
By "don't fool around", an example is:
spyware stay in your cookies
This, frankly, is rubbish.
The other aspects of the analogy you posted are somewhat creative, though not especially apropos, to my mind.
(BTW "unlucker" is spelled unl
ocker.)
