Ubuntu/Lubuntu 16.04 --- How to install "free" Sophos antivirus on Lubuntu 16.04

Recently, the Lubuntu upgrading fail from 14.04 to 16.04 directly so that I have to reinstall Lubuntu 16.04 freshly. When I install Comodo antivirus by Geb Utility, it stop and tell me the libssl0.9.8 miss.

I am not sure what happen so that search Google for answer. The Lubuntu 16.04 use libsso1.0.0 by default, not libssl0.9.8. I try to find out the alternative method to install the necessary version, but the result still fail. In the moment, I will give up the Comodo antivirus install on Lubuntu 16.04, although it work nicely on Lubuntu 14.04.

The Sophos antivirus for linux is another choice but it is command line only. For downloading it from the Sophos Official WebSite, we have to fill the form to get the download link.

Once the download finish, we will extract the compressed file next to execute sudo sh ./install.sh command in terminal.
In the install process, I choose the free Sophos version based on legal usage so that it just can be used on Command Line environment.

After the installation finish, we need to install update firstly by executing sudo /op/sophos-av/bin/savupdate command.

To check status of on-access scanning

As to the related CLI command, the following list will be the important one:
To enable on-access scanning by doing sudo /opt/sophos-av/bin/savdctl enable command

To disable on-access scanning by doing sudo /opt/sophos-av/bin/savdctl disable command

To turn live protection on by doing sudo /opt/sophos-av/bin/savconfig set LiveProtection true command

To turn live protection off by doing sudo /opt/sophos-av/bin/savconfig set LiveProtection false command

To scan Volume Boot Records by doing sudo savscan -bs=/dev/sda1 command

To scan Master Boot Records by using sudo savscan -mbr command

To scan System by doing sudo savscan /  command

I need some time to realize whether its function is good and operation is friend. Maybe this content will be updated later.
