You said you use MB to complement your current AV suite, in short finding a complementary AM.
Do not run Emsisoft AM besides your security suite (if you intend to) as it does not provide that compatibility anymore, for the good. It's specially not compatible with the likes of Kaspersky, Avast etc. On forums, I've noticed corruptions on quite some systems in this regards (even when EAM was installed in passive mode) and have experienced myself too.
For real-time protection (discarding Comodo, Sophos), I'd prefer EAM as a standalone suite and Zemana as a complementary AM with most AVs.
For 2nd opinion, I'd prefer Zemana, MB, HMP and EEK. MB does detect minute stuff and invisible changes that others miss, though overall detection has not been as good as Zemana.
Dr.Web CureIt is powerful. However, the amount of FPs negate the overall results for me. NPE & McAfee GetSusp are testers' favorite tools too, use for troubleshooting with caution.
