In the Linux Security forum we often ask victims of (perceived) security breaches to gather log files and parse them for leads using Logwatch.

Here is a patch for install_logwatch.sh that will install Logwatch in a temporary directory and prepare it for receiving log files...

The resultant monstrosity is resource-intensive, impossible to configurable and rarely used. Researching something else (as usual) I came across this rather good presentation (PDF) about creating ones own AV signatures: Writing ClamAV Signatures and not long after that I found R-fx Networks' Linux Malware Detect....
