Then let me try to explain it in more detail. ;)

No.

It's not used, because freshclam is run in foreground mode, i.e. it 
doesn't fork and thus tracking the PID via a file is not necessary.

It can only write the file if the directory exists.
The sysv init script creates the directory, but since it is not 
necessary for systemd, the service file does not create the directory.

The service file could also create this directory, however that's not 
straight forward in this case, because the PidFile path can be changed 
in the freshclam.conf file. Thus the service unit would have to parse 
that file and as it is not a simple shell snippet with 'Key=Value' 
entries, but rather contains 'Key Value' lines, one cannot directly use 
it as EnvironmentFile in the service unit.

As this warning is completely harmless, when systemd is used, I don't 
think it's worth to invest a lot of time trying to fix this.

But if someone finds a simple solution, it can be applied.

Best regards,
Andreas
