Detection approach

Malwarebytes uses behavioral-based detection that identifies threats by their actions rather than file signatures. This makes it effective against zero-day threats and fileless attacks. Avast relies more heavily on signature-based detection supplemented by machine learning.

Best use case

Malwarebytes excels as a secondary scanner alongside Microsoft Defender. Its ransomware rollback feature can restore files encrypted by ransomware automatically. Avast works as a budget primary antivirus but carries privacy concerns due to past data collection practices.

Pricing

Avast is cheaper at $399 per year for 25 seats. Malwarebytes costs $499. Both are below the market average. However, if you need a primary antivirus, the extra $100 for Bitdefender or Norton is a better investment.
