Sorry if the answers to this question are obvious, but I'm very new to Linux, so please don't assume I know anything, whoever basic or commonplace about Linux and it's programs.
What I'm wondering is, what security software should I be running on Linux, please? On Windows I use Avast! Anti-virus, Malwarebytes Anti-malware, and Zone Alarm (a firewall), and all are very good (and free!).
Tasmania's Department of Education has gone to market for anti-virus software for its 40,000 desktop PCs and 1,000 servers, specifying solutions must be able to secure not only Microsoft Windows, but also Mac OS X and Linux, in a move that once again raises the question of whether the alternative platforms require dedicated security software.
