I would personally also consider Vipre (use Slashdot) and ZoneAlarm as both made their names partly from their excellent firewalls. Sophos, ESET (use eBay), Kaspersky (try eBay), BitDefender, Avira, Avast/AVG (use Newegg), TrendMicro (try Alibaba), Norton (use Newegg), McAfee (use Newegg) are all okay. Doing this I'm assuming you follow the other persons advice and purchase a security suite as the main line of defence. You can even set periodic scans with MBAM and Windows Defender. They made their name with their file assassin tech for removing already known infections. Keep ur MBAM but turn off real time protection. There are plenty of tools that will take care of this for you, like SysHardener or OSArmor. Don't think on stacking software over software, think on one software solid enough to protect your system. One program, with everything you need, real time protection, anti ransomware, information loss remediation, bidirectional firewall, behaviour blocker. Bitdefender Total Security, Kaspersky Internet Security. Don't think on antivirus and anti-malware, just grab a suite. So here's my advice: get a security suite. Of course Windows Defender ain't working, it's disabled whenever an antivirus is installed, and that's what Malwarebytes Premium is. If you don't feel safe with Malwarebytes, ditch it.

Keep your software list to the bare minimum. Not only having multiple antivirus will making your system slower and possibly buggy, but you're installing more and more software software have bugs, security holes that can be exploited to gain control over your system. One thing you want to know about security: the more software you have, the biggest attack surface for cybercriminal.

Real time protection, web protection, anti ransomware. Why would you want to do that? Malwarebytes 4 Premium version is an antivirus, literally.
