Mozilla haves multiple privacy and security products but i don't see a antivirus product like avg antivirus, avast or mcafee. it should be a great idea if mozilla also make a antivirus program.
Thank you for your suggestion @Jeppie. However, I personally believe that Antivirus software are a scam. Wouldn't be better to run an operating system that doesn't get easily infected or crashes?
I've been running Linux for more than a decade and malware has become an "alien" term to me. I also have a Macbook, and macOS has so many security features, that installing an antivirus would be a waste of space.
What Mozilla could do, is to partner with Bitdefender or another brand, and maybe give them a Mozilla Badge of Approval for Internet Security.

Remember that malware is a business, and some companies profiting from it don't want the problem to be resolved.
