Avast free and malwarebytes

Hello community, i have never used malwarebytes before and am wondering if it is a legitimate spyware free program? And if so, does anyone know if it interferes with avast free ver. ? - thank you

Very good program that could run side by side with avast.

Welcome to the Avast forum Kevbeck look at my sig below I’m also running Avast free and malwarebytes too.

State-of-the-art scanner, often recommended here, and other places.
Demand (free) and resident (subscription) versions available.

Highly recommended.

You only need to browse the forums and see the references for it in the viruses and worms forum, not to mention the many signatures of forum members.
