Antivirus Module is not working
It might be possible that your antivirus module might not start. In this case you have to put new files into your working directory. Do the following Debian/Ubuntu sytems:
Go to /etc/clamav/ and open clamd.conf. Find the database and where it is located. Normally it will be /var/lib/clamav. Find a server running clamav correctly and copy the files from /var/lib/clamav to server where your clamav is not working. Start the module again and you should be good to go.
