Out of the box the ESET NOD32 antivirus for Linux 64bit running on Linux Mint 18 wrongly installs the service configuration file as an executable, flooding the system log:/var/log/syslogwith such text:Configuration file /lib/systemd/system/esets.service is marked executable. Please remove executable permission bits. Proceeding anyway.
syslog: Service is marked executable. Please remove executable permission bits. Proceeding anyway

I am showing ESET NOD32 service as an example, but this applies generally to all /lib/systemd/system/*.service files.Long-listing the service file:ls -l /lib/systemd/system/esets.servicereveals the execution bits set:-rwxr-xr-x 1 root root 360 Sep 22 08:53 /lib/systemd/system/esets.serviceSolution is to set the proper user rights:sudo chmod 644 /lib/systemd/system/esets.serviceAnd you will no longer see such message in your syslog.I have already reported this cosmetic problem to the ESET development team.
