@SearchLight Unless you want more hassle with your configuration, I suggest you ignore the recommendations for software like anti-executable and anti-exploit. You can use Emsisoft Anti-Malware for your real-time protection sufficiently and you can add more simple and less-hassle additions like an on-demand scanner (e.g. HitmanPro is quite fast and reputable) and/or an ad-blocker (helps you block malvertising - there are reputable and free extensions for most browsers to do this like uBlock).
1. You can use Emsisoft Anti-Malware and VoodooShield in combination but ask yourself, why do this in the first place? You'll be just as protected using either on their own. Make good decisions and use your primary real-time defense as a backup friend and you'll be fine. Sure you can get an alert for every new unknown process spawn but you'll have the Emsisoft BB and even if you get an alert from an anti-executable, why not just not run it in the first place if you didn't want to run it? Run wisely.
2. You can use Emsisoft Anti-Malware and HitmanPro.Alert in combination as long as there are no compatibility issues (I am not sure if they are compatible) but ask yourself, why do this in the first place? You'll only have two security solutions in real-time potentially overlapping each other considering Emsisoft already provide exploit mitigations and ransomware protection. You don't really need both. In my opinion that is over-the-top past using EAM with VS.
3. You can use Emsisoft Anti-Malware with 4 on-demand scanners but it doesn't necessarily mean you'll be better protected. On-demand scanning will require you to spend time making the manual scans and if you rely on scheduled ones then you may be unexpectedly interrupted and have your system resources used up more while trying to work (depending on the scenario). It neither means that an infection which was surpassed by your real-time security will actually be identified, one or two is enough in my opinion.
4. Emsisoft Anti-Malware and Zemana Anti-Logger in real-time? Emsisoft already intercepts keylogger installation attempts very effectively, there's no need for it in my opinion.
Emsisoft Anti-Malware is a full Anti-Virus replacement despite being titled Anti-Malware and it is supposed to be used as a full suite for protecting the user. It offers more than enough protection components which have been developed over numerous years by skilled engineers and researchers to get to the level of quality and reliability is at now, and it is indefinitely sufficient to protect someone when being used alone as primary real-time protection. The statistics from malware testing by both general people who may make mistakes and tests conducted by professional security software testers who publish regular reports speak for themselves, not to mention that they use an engine alongside their own from another award-winning and extremely popular vendor, Bitdefender.
Stacking software upon software will never necessarily help you. It adds more attack vectors which can be potentially exploited and time and time again I see that most people don't really take notice. The attacks that paranoid users stacking software upon software are thinking about are likely to never ever be fired in your direction - traditional malware attacks will be handled by Emsisoft Anti-Malware perfectly fine, and many other Anti-Virus products perform a spectacular job. Unless of course you own a large company which automatically makes you a target.
The truth is that nothing is ever "enough" to close all holes which can be shot at by a bullet - but that doesn't mean you should have everything. Every-time your security product flags a new program as malicious based on behavior or blocks a download, you've just dodged a bullet. Aim to reach the point where that rarely has to happen due to good decisions, and hopefully if you ever make a mistake which all of us make at some point, your reputable real-time security software will intervene and save the day, just like a good friend would if you were in need of assistance. Everything else is totally unnecessary with the exception of an on-demand scanner or an addition like an ad-blocker for improved user experience when browsing and to help direct targeted malvertising attacks.
Take it with a grain of salt because it is opinionated. Use good real-time as primary, add a few simple additions for ad-blocking and make a backup... You're good to go.
