Well, Linux is not as susceptible to virus infections as is Windoze, but it is good to scan email attachments for viruses! Most of us use ClamAV - open source, freely installable, and in the software repositories of most Linux distributions. There are Linux versions of many commercial A/V packages such as McAfee, et al because they are used to scan for Windows viruses coming through Linux network gateways before they hit the Windows machines. Also, I use a commercial scanner, F-Prot (from an Icelandic company), when I am cleaning my clients' Windows systems of viruses. In those cases, I use 3 scanners (the other is McAfee for Linux) since they each catch things the others don't, and when scanned in the most sensitive mode, they all give false positives. So, in such a case, I look for the ones that at least 2 of them agree on! :-) This process takes computer time (not much of mine - I script the process), but is very effective in that I have always been able to clean my clients' systems and not lose any of their data! :-)
