how does firefox block malware and viruses?
on my last computer i got a virus while downloading torrents (using internet explorer, yes i know stoopid)
but i just got a brand new pc and its got protection software and i was just wondering what the difference is security wise between internet explorer and firefox?
is there a reason for me to download it and use it versus just keeping my regular internet browser?
If you're downloading torrents it really doesn't matter what browser you use. The files are downloaded with your client anyway, not your browser.

That being said, firefox has better security.
From what I hear, Opera = security though.
I personally prefer firefox though. But I have like..every browser.
