I have been seeing hints of AnitVirus for linux.
Any suggestions as to it's avaliblity, quality, cost, value to system security

Like wise has ther been any thing said on Spyware or spam/pop up blockers

You don't really need anything other than a firewall (even though I don't have one, too lazy :tsk to block any malware. Only 3 known viruses have been written for *nix. Same for spyware. If you use Firefox and Thunderbird, they have spam and popup killers.,

If you are using your linux box as a file or mail server for MSWin boxes, then the Linux anti-virus software is appropriate. Otherwise, what LavaDevil94 said is on the mark.

I use ClamAV which is an Open Source virus scanner, it works great.
For email programs like Kmail, Sylpheed and webservers like apache there are plugins/modules for.
So that you can scan your mail with it. For outgoing as for incoming.
Even filescan of your harddrive works.

It is available for Linux, but also for windows (and works with outlook).

Great product..

It knows over 23000 virusses and trojan horses... just try it and see for yourself.

AVG has one for Linux, but only i386 (not powerpc):

You can download the deb and put it in your home folder and run "sudo dpkg -i avg85flx-r812-a3371.i386.deb" (or whatever the current filename happens to be); and note: if you go to download.com and search for "avg", you'll see that it's widely used and loved.

And thank you eisman, I just installed ClamAV (ran "sudo apt-get install clamav"), per your suggestion (and some extra web searching).

Also, if anyone reads this ("over 6 months" old) thread, why would you not put antivirus software on your computer (e.g. is it stealing resources)? Just because Linux and Mac OS don't get the heat like Windows, doesn't mean there aren't viruses and malware (or even passing along of said things).
