I don't care if it isn't fully on-demand, I like having many scanners. Haven't noticed any performance decrease either. Why is there custom install if it "cannot be used as a standby"?
Sigh, I'm more of a practical person than theoretical. Please don't give me the same old generalization repeated far too many times. For example, I've installed Avira as on-demand for years without problems.
Who doesn't use MBAM. What about HMP, EEK, CCE, etc.? I know all the alternatives, being a co-author of Probably the Best Free Security List in the World.
Seriously, can someone just answer the questions?
