I might be a little slow about this, sorry for the dumb question, I know theres an old trojan that bricks
your psp a long time ago.

But can you get infected while using the browser, or does the custom firmware already have a built
in security patch thats immune to viruses? Or is it just impossible?

proboblt impossible, better the psp than my computor.

eh... well now that there is a debricker there really wouldnt be any point in worrying about that trojan would there? as well im pretty sure that was hidden in a false custom firmware. the psp is sort of awkward so most if not all viruses wont be a problem.
