you can find lots of software for linux on the web... try these sites:
http://www.freshmeat.net
http://www.sourceforge.net
or for rpm packages:

you don't really need an antivirus as gnu/linux is designed to be secure when
properly installed and administrated...
secure means that your users don't need to be worrying about any viruses... it also means they don't have to worry about doing any damage to the system... the idea is that _nothing_ one of your users does can damage the system... only _you_ (root) can damage the system... whenever a regular user is able to affect the system configuration in any way, then that is considered to be a security flaw, and the flaw will need to be fixed... no regular linux user should EVER have to worry about doing anything bad to the computer (unless they are root)... no linux user should EVER need to feel afraid to check their mail, or to accidentaly open an "infected" attachment...
this is in stark contrast to windows, where any user (not just the adminsitrator) can do incredible damage to the system with just a few clicks; where any user must be somewhat paranoid about opening their mail...
there's lot's of other windows "goodies" you won't need, such as adware removal tools or disk defragmentors and stuff... this is a TOTALLY different system...
of course lots of people install antivirus software on linux servers to protect _windows_ boxes... for example, a linux mail server that scans attachments (looking for windows viruses) so that the windows users' machines don't download something deadly from the linux box...
another example of typical anti-virus use in linux is if you are a business/company and you use linux but all your customers use windows, and even though it doesn't affect _your_ computer if the word document you're working-on has 30 assorted viruses, it would not look good if the document sets off like 30 alerts on norton or whatever when your customers receive it... so you'd wanna make sure you're giving them a clean file, for their computer's sake, and for your company's image sake...
browsers such as mozilla (the most popular browser on linux) make pop-up blockers pointless... mozilla's had the option of blocking pop-ups for a very long time...
"enhancements" is a very broad term, perhaps you could be a little more specific... in the free software world, enhancements quickly become features: usually, if someone finds a better way to do something, it's done... there's no beating around the bush... the enhancement isn't kept on the side as a shareware download or something... i'm having flashbacks of "
analogx"... i used a bunch of his utilities and enhancements and stuff when i used windows back in the day...
music, well, xmms is very good and it comes with your red hat 9... the only thing is it doesn't play mp3s out-of-the-box on red hat 9, as the mp3 format is NOT free software... but you can download mp3 support for xmms yourself
here.
you might find this table handy for finding "equivalents" to windows software:
http://linuxshop.ru/linuxbegin/win-l...en/table.shtml
there's PLENTY of linux software out there (and on your distro's cds)... it's just a little weird at first to grasp the concepts and implications of free software distribution...
ps: red hat 9 is not supported anymore... i really suggest you get your hands on something supported, and with more advanced features, such as
mandrake if you can...
