well i mean the main thing about downloading porn is knowing the difference between an .avi and an .exe
also i've only gotten a virus once, and it wasn't even porn, it was from a weird foreign streaming website i found when i was trying to watch (I believe) an episode of Bored to Death.
And I typed in what was happening on google and found other people having the same problem, and additionally people who had already solved the problem for them. a couple hours later i was all set. (would've been quicker if i had just grabbed malwarebytes though).
for real though why would you bring this here?
