web server - Debian webserver malware scanner

I was wondering if there was a malware scanner for websites with up to date exploits for use on a Debian webs server with Apache2.2?

Vulnerability scanners are great, but I also want to be sure that undetected hacking attempts that infect my files with malware get's detected.

I already uses these tools to monitor my system:

• Clam AV (anti virus)


• Paros (vulnerability scanner)


• Wapiti (vulnerability scanner)


• Scrawlr (vulnerability scanner)


• W3af (vulnerability scanner)


• Mod_security

EDIT:
I am looking for something like the Sucuri scanner just installed on my webserver.
