It is hard to trust the old antivirusis because when I install a new antivirus after an old one it always find virusis.
This is due to the peculiarities of the work of antiviruses. Some programs can be identified as viruses. Sometimes you tell the antivirus to trust the application. What the new antivirus found is not always a virus.
I hope that the developers of ROMAD antivirus were taught this moment and their product will be calculated by viruses, but not by useful programs.
