This is more common than you might think. The most common complaint
resulting from this (on the clamav list) is not catching viruses through
(MailScanner|AMAVIS|Other) scanners, but from the command line the scanner
works fine.

The most common cause is installing clamav with two differing methods, RPM
then source or visa versa which would generally result in two different
--prefix designations. The best thing you could do is uninstall both
installations and reinstall, and always install with the same method. Make
sure and locate both sets of binaries and libraries (example: locate
libclamav.so && locate bin/clamscan). I would reinstall ClamAVModule after
you have done that.
