After looking at other options I decided to try installing CAV, I tried it before & had problems, sadly it is still giving me issues.
Firstly I have Linux Mint Cinnamon 18.3 running kernel 4.15.0.29
I downloaded the deb file & run it in Gdebi which complained about unmet dependencies (libssl0.9.8_0.9) however I managed to download & install the missing dependency & this time the installation completed, at the end it said it has to be configured with the command sudo /opt/COMODO/post_setup.sh
This I did & to be safe rebooted, after the restart it opened fine but the shield on the right had a red cross with the message "File system filter driver is not loaded"
It asked if I wanted to run diagnostics, I did & it said I needed to enter the command "sudo /etc/init.d/cmdavd restart"
It said "successfully restarted" I rebooted again to be safe, Comodo starts automatically but still shows the red cross & says "File system filter driver is not loaded"
It updates definitions ok & scans ok but it would appear that in this state I have no realtime protection.
I have seen people say it works ok on their system so what else should I be doing.
Thanks in advance.

Read the LQ Rules...you marked your other thread SOLVED, which is (essentially) a duplicate of this one. And you did so without following up or answering questions in your other thread, that are directly related to this one.

Thread reported.

That's just a bug in comodo. You can use it like that. But I would advise clamav instead.

I'm guessing here, but...
you restart with ...then you reboot and things appear not to be working ('tho you don't tell us how you know that.)

Try restarting the daemon and NOT rebooting.* What do you see then? Is it working?
If it is, then your problem is that you've not configured the daemon to start at boot. Search how to do that in your distro.

*One of the really great things about Linux is that we can restart a server without having to reboot the box.
I've had production servers run without rebooting for over a year, but could reconfigure and restart web, email, and any other server I needed to many, many times.
