Disable clamav services

[Eugene Sobolev]

Hello.
We are using Proxmox Mail Gateway in conjunction with another antivirus solution via custom script.
Even though the clamav parameter in the admin section of /etc/pmg/pmg.conf is set to 0, and the clamav-daemon service is disabled, it starts every hour.

This happens because

PMG::Utils::service_cmd('clamav-daemon', 'start');

is executed in /usr/lib/pmg/bin/pmg-hourly

Masking clamav-daemon.service is a bad idea - pmg-hourly.service will fail. Among other things, it is responsible for synchronization with LDAP, and in monitoring it will be unclear what exactly broke

I suggest a simple patch

 exit(0);

PS: Restarting the clamav-freshclam and clamav-daemon services can also occur in /usr/share/perl5/PMG/Config.pm when changing antivirus settings via the web gui.
