Hi first off I am a newbie so please be kind just wanted to ask if there is a Linux (I run RedHat7.3) version of say PC-Cillon. Or is this a matter of setting up my firewall. On my windows machine PC-Cillon has worked great at stopping all the viruses that I receive.
I have the Mozilla browser (use it as well to get my email) and have set up my own mail server on the box and have received mail thru it but I don't want to anymore until I get some sort of protection software installed. Any help would be great.

Thanks in advance.
If you think you need av software you can try two programs: amavisd, which controls virus scanning, but is not itself a virus scanner, and clamav which is a virus scanner.
If, however, you are not running Windows software, the need for anti-virus software is low; not zero, but still very low.
Originally posted by defa0009 Really! I get a lot of virus reports when getting my email on my W2K machine so wouldn't these viruses be able to do damage on my RH box?
You are running linux, not Windows. The viruses are aimed at corrupting the windows environment, not the linux one. If they are simple executables, they won't run. If they are scripting viruses like Melissa, you can't be harmed because linux doesn't support Outlook, VBA, and a host of other mechanisms by which Microsoft and its programs can be infected to your harm.
This is even more true if you run as a normal user. Never, never, ever (strong enough?) run as root except to make needed changes or updates to your box. The inherent security of linux will largely limit any malcious damage to your "user" and not to the box as a whole. This is the real conceptual difference between windows and linux from the user perspective. All home users of Windows, for example, run with complete admin powers, so any command they run affects the box as a whole. On linux, if you run as a normal user, a command as wildly destructive as
#rm -rf /*
will limit its effects to you and your home directories and any files that have you as user and or group; but the box as a whole will be safe. Yes, you will have some recovery to do, but your system will continue to run.
Hello, defa0009.
I use f-prot to scan email, attachments or downloads I or someone else may view in Windows.
I am wondering if f-prot would pick up this type of PDF hack.
