Malwarebytes vs Avast 2026: Which Antivirus Is Better?

Malwarebytes and Avast are popular cybersecurity solutions, but they serve different purposes. Malwarebytes focuses on malware removal and straightforward security, while Avast combines real-time antivirus protection with additional privacy and network security tools.

Both offer free and paid versions, although their features differ significantly.

In this Malwarebytes vs Avast comparison, we evaluate malware protection, system performance, features, pricing, and usability to determine which antivirus is better in 2026.

Malware Protection

Malwarebytes specializes in detecting and removing malware, spyware, adware, and potentially unwanted programs (PUPs). Its paid subscriptions include real-time protection, ransomware defense, and exploit prevention.

Avast combines signature-based scanning, behavioral monitoring, and cloud-assisted threat detection to protect against viruses, ransomware, phishing, and malicious downloads.

In AV-TEST's August 2026 Windows evaluations, both Avast Free Antivirus and Malwarebytes Premium received maximum protection scores of 6/6.

Winner: Avast. Its free real-time protection provides better everyday security without requiring a subscription.

Performance Impact

Both antivirus products aim to protect computers without significantly affecting everyday performance.

Avast also performs well during browsing, streaming, and office work, although additional background security features can increase resource consumption.

Full system scans may temporarily affect CPU and disk usage with either product, especially on older computers.

Both received maximum performance scores in AV-TEST's August 2026 evaluations.
