I'm no anti-virus programmer but I would think that this is where "vulnerability scans" known and potential avenues malware can take would come into play, "behavior" scans would also come into play, "cloud" based scanning. You're right if there's no known signature then a signature based scan wouldn't work. However there are know signatures for know malware and just abandoning them wouldn't be prudent either or not using signatures once they are made.
I get what you're saying but I don't agree that just stopping the use of signatures is prudent nor security minded when taking a holistic look at it.

Avast is in their list, but only on Mobile devices, not PCs. That's terrible, because some of the worst infected computers I get from Customers have any of those 3 recommended as "BEST". These 3 AV programs don't do as well on the 
The other AV programs that are highly rated, such as Kaspersky, Bitdefender, Avira, and ESET Nod32; are more like 10% infection rate or higher. I think Kaspersky is more like 50% infection rate. Every computer I've seen in the last 5 years with that on it is so completely filled with viruses and spyware, a drive wipe must be done and Windows reinstalled to get rid of all the viruses Kaspersky let through. Take a look at these test results from AV-TEST: 
TrendMicro paid does a good job, but not as good as Norton Security Deluxe or Avast Premiere in my experience. I believe that Kaspersky and Bitdefender especially are paying the AV-TEST guys to rate their programs much higher than they really perform in reality.
Having deployed AVs in large corporate networks for 30+ years, there is something wrong there. There are Zero Fortune500 companies using Kaspersky or Bitdefender on their business networks.
If they were that good, wouldn't Fortune500 companies have adopted and begun using those products to protect their computers?

In a couple of cases, it was human error, as one of my Clients used to give all 3 of her laptops to her Grandkids in lieu of babysitting them (she has 6 grandkids). The teenagers when they would come over would each take a laptop and go into one of her bedrooms AND LOCK THE DOOR! They wouldn't come out for days. When she called me to fix the laptops, the AVs were always uninstalled or disabled at the least as they all knew that AVs slowed down their online gaming sessions. I told her that they shouldn't be left unattended to do whatever they want to the computers in private with no parental guidance. She simply ignored me, and kept giving me the broken laptops to fix always with the same type of problem==the AVs uninstalled. I needed the money, so I just gave up and shutup and just fixed them! 
I don't know. I can only tell you about my experiences, not theirs.
