  1. Hi,

    Today I tested both Comodo and Sophos on a 2018 ubuntu like os with kernel 4.13.0-45
    In the end it works, but for this kernel no ‘on access’ scanning. For both virusscanners there were
    many errors during install referring to kernel compatibility. Be warned!
    You can use them, but only the ‘on-demand’ option works in kernels higher then 4.0
    Since this article was written in 2018…..,maybe update that info.
    I invested a lot of time installing these tools ,surfing the net for solutions, testing, finding out about the kernel limitation…. A lot of wasted time in fact.
    The providers of these softwares have a very easy support solution; ” Reinstall version 14.04
    of ubuntu, install our virusscanner and close the ticket please………

    Bitdefender free works. With a gui as well. no realtime or ‘on access’ in this software however….
    For an interesting easy automatic installation of many softwares on a beautiful linux distribution:

    Good luck!
