avast should spend more time to fix their compatibility issues and all reported issues before thinking about adding new features
avast is one of the worst programs to play alongside other security products because it just makes other programs stop working or crippled, for example, outlook in v17.9
v17.9 made me uninstall avast immediately due to higher memory usage (perhaps, fixed for now) and some weird, silent compatibility problems. I can't use novirusthanks OSArmor anymore because avast just makes it unusable
that's not good
