ClamAV isn't going to do any good in securing your server. ClamAV is not an antivirus for Linux, but rather for the mail server, all it does is scans emails for viruses server-side, so users download email won't get viruses, it doesn't protect the actually server.

You want to install RKHunter and/or CHKRootKit
