How to Install Free Sophos-av

The problem with Clam-av is it does not prevent maleware before it gets into your system where as sophos does protect it from at least 11 million some hundred thousand known maleware. If LL is running on Ubuntu 16.04 there should be already an anti-virus and firewall built in, at least according to their website which comes with it.
Secure 16.04

"With a built-in firewall and virus protection software, Ubuntu is one of the most secure operating systems around. And the long-term support releases give you five years of security patches and updates."

Secure Boot which comes with HP`s that have Windows mounted on the newer systems is supposed to protect from Boot Kits which can be particularly difficult to detect and remove and can take control of your computer without you ever even knowing. All Microsoft desktops and and laptops with Windows 8 or later must be equipped with Secure Boot. On mine I can switch from Secure Boot to Legacy. Problem is it is a pain to work around adding Secure Boot back in. For most larger Linux Distros it is not a big deal as they have keys recognized by the UEFI so booting is not a problem. Smaller Distros do not generally have a recognized key and won`t boot into a UEFI system without a workaround. Linux has become quite popular around the world and has recently attracted the attention of hackers as recently demonstrated on Mint and Soft pedia.
My system 4xIntel® Core™ i3-4170 CPU @ 3.70 GHz UEFI .I am retired with no need and no desire to dual boot. Like things simple and easy, Life`s hard enough with enough complex problems and complications of it`s own without making more for myself.

That is a big promise by Sophos to protect from that much known malware. Honestly, how can we really know that if the program is proprietary? We simply cannot, and while I agree with you that ClamAV doesn't detect a virus/malware as soon as it is introduced to the system, you can always scan each file you download. Personally, I only download files that in some type of video format (mostly .mp4, .mp3, .avi, etc.) so these things pose little risk. Linux, for the most part is secure. As long as you watch what you download apart from programs from the PPA's you will usually encounter no issues. Also, I know many of us Linux lovers enjoy open-source presence in our systems so that's why I recommend ClamAV/ClamTk. Some are migrating from Windows because of all the nasty tricks they are playing against their own customers and are finally wanting to regain their freedom and they see open-source programs as a way to do so.

Run Clam-av or nothing if your all that confident. I am not here to argue about which is the best and safest av. I was just trying to be helpful. Linux can get maleware and a Google search of experts much more knowledgeable than I will confirm the risks but as you said Linux gives you the freedom to do it your way.

I never said Linux couldn't get malware and my intentions are not to argue with you. I am simply stating the facts that Linux is generally safe if you only download applications from the Ubuntu software center. On most occasions, it is the users fault for getting a virus. Always research the software you are looking to use before downloading it, it is simple as that. You could always use VirusTotal if the file is 128MB or under in size.
