i'm well aware they have virus scanners for linux, but typically they are for when you share the a drive either with windows locally or on a network, so if you are downloading files in linux, you don't inadvertently infect a windows machine that access that file.
And the nice thing about linux is that you can easily repair any damage done through terminal or recovery mode. On top of that since everything (in a way) is compartmentalized you don't really have to worry about a virus running amuck.
And a very simple way to REALLY slow down and or stop a virus in its tracks, is to partition your drive into multiple sections, each part assigned to different sections of the file structure:
Partition 1 - /home
Partition 2 - /etc
Partition 3 - /var
Since the OS knows how and what to look for (along with where and what to do with things) it isn't affected.
Unless the viruses is "smart" and knows about this, it will just endlessly look for whatever since technically each part of the filesystem is in its own "hard drive". I have the same crap happen when I install patches (IE Mass Effect Bring down the Sky). My Steam folder is on Beta (my RAID 1) while it is looking for ME on Alpha (C:/). Since it cannot find, nor does it know to look on other drives, the patch/DLC crashes.
;_; I scare myself sometimes with the knowledge (or at least parts of the knowledge, some of which needs to be elightened upon) that is in my head.
@ OP - if you feel you are unsecure, you can harden the kernel from within Synaptic. I forget what you need to look for, but I think you can try a search for harden you may find it.
Also setting up a firewall with custom rules works as well. I know Fedora and OpenSuse (I think) comes with a fully customizable IPtables complete with a GUI to do this. I love Fedora and hate it at the same time. only because there is so much you can do to make it secure. I had it installed on my T43 for the longest time and had a couple hackers (friends of friends of friends) try to break in. They failed....badly. >.> Had a friend make me a really nice firewall Edited by Lord Xeb - 4/20/11 at 12:10am
