Sophos AV (Linux) with Postfix and Spamassassin

Hi joea

What is the version of the SAV for Linux you are currently using? 

None, at the moment.  A few months ago I downloaded and installed the current version on a test Linux PC.   I wish to now attempt to integrate whatever the current version is into my SOHO mail server to add virus scanning.

My current understanding is that AMAVIS-new is the hot setup, using CLAM-AV as the AV/malware scanner.   I can of course use that, but Sophos is my preferred AV/Malware software.

Sophos SAV for Linux 9 (Standalone version) has a declared End of Life of 7/30/2023 or sooner and is no longer an available product.  In my opinion you time would be better spent with an alternate product.  This discontinuance is unfortunate for the many Linux Desktop users.  In 2017 I tested six Linux anti-virus programs, based on the A/V Tests article of 2015 (why hasn't there been an independent test since then?). including Avast, BitDefender, ClamAV, ESET NOD32 (a  64bit application which requires 32 bit multilib installation), Sophos, and Symantec. Sophos was free, and had a very high detection rate and lowest memory usage.  ESET, the highest detection rate for windows and linux malware, was low cost ($49/yr) and lower memory than Sophos, so it was used for two years until they failed to provide timely support to a failed update.  Then in 2019 I moved to Sophos, since AVAST and AVG were file server only products and I could not get Symantec trial without payment and Kaspersky was sanctioned against by USA.  In all the years of using anti-virus I have not had one warning.  HOWEVER in 2013 on a Windows machine running TechProtect (a ClamAV for Windows variant), my machine was compromised by ransomware.  So I don't really trust ClamAV to be effective (as was shown in the A/V Test results) .  In my opinion, and lacking a more recent Linux/Unix test of anti-virus products, it would seem the only product for standalone Linux is probably ESET Nod32, since detection effectiveness is the reason one runs anti-virus in the first place.  That's my two cents.  Cheers and so-long, BrianA_MN
