"Malwarebytes Anti-Malware
Since some anti-malware utilities are trying to expand into the on-access malware scanning game, we figured we would ask what Malwarebytes, one of our favorite anti-malware tools, will and won't protect its users against. Malware Industry Analyst Adam Kujawa explained that Malwarebytes aims to detect as much malware as possible. However, their focus isn't on those classic threats like viruses and worms:
Malwarebytes Anti-Malware hunts down most often zero-day or zero-hour malware, a term our community uses to explain malware that has been newly created and released on the web. Zero-hour malware can be any type of malware out there that traditional antivirus products have a hard time detecting, so it's an additional security measure to protect the user from the kind of malware they are most likely to encounter while surfing the web.
Put simply, Malwarebytes aims to protect you against all manner of malware, but common viruses and older threats aren't included. Their goal is to stay on the forefront and protect users from new exploits, trojans, backdoors, adware, and spyware. For everything else, you'll want a traditional on-access security tool. "
So in general YES. but all others is fine with free versions of something like Avast.
