Clamav is a free (GPL) virus scanner for Linux and other Unix systems. It seems to work well. The price is right.
There are very few viruses for Linux, so few that most people don’t waste their time with virus scanning. But if the machine is acting as a server for clients that are vulnerable to viruses–cough–Windows–cough–it’s a good idea to have antivirus software on your server, just so you know your clients are safe.
Debian packages are in Sarge and Sid. Source can be downloaded and built from the link above. Once it becomes better known, it should appear in RPM distributions such as Red Hat in time.
It’s just a scanner, but if it finds an infected file, you can clean it manually with free tools you download elsewhere. Clamav will take care of alerting you, the price is right, and the platform’s right. It’s always been hard to find antivirus software for Linux of any sort, so Clamav is a welcome addition to the family.
We’ll talk a lot more about servers in the coming days.
