I tried to install Bitdefender Antivirus protection on the last Elementary version 5.1.2. but it did not work with the command line.
(I want to use bitdefender, because I use it for my W10 and Mac devices)
Q1 is it possible at all? Q2 how do I do this when it is possible? Q3 if it is not possible with bitdefender , is there an alternative?
