best browser?

[wupwup]

i just got the internet on my old pc. yay me. i need to get a decent browser for it but it is verry slow. (2.8ghz singlecore processor and less than 1gb ram.) so i need a lightweight, secure browser. im thinking about firefox but dont know wich versin. thanks
i would also like some antivirus software. i was thinking of zonealarm free firewall and avg antivirus. are here an better ones? thanks

just got firefox 3. it seems verry slow. then again ill install the os again in a min and see if it speeds up. isnt google chrome verry insecure? opera sounds good though. what do other people think of it?

thanks. downloaded opera and firefox and so far opera seems the winner. i will probably miss out on some plugins and whatnot but its much faster/looks nicer. thanks everyone. i also downloaded avira before i formatted to seewhat it is like and i hated it. so im using avast. how good is avasts firewall? can someone recomend a better one? thanks

well avast dosnt have a firewall but what i was saying is is it capable enough to negate the need for one? if not what should i use? thanks
