Dear Ladies and Gentlemen
I propose to remove PidFile-Handling from ClamAV and handing it to the init system as it seems already to be the case in most deployments. Please have a look at the following PR and let me know if you oppose or need support in integrating your stack.

Best regards,
Hanspeter
