Antivirus protection

Malwarebytes is very powerful and demonstrated pretty good malware detection rates, as it detected more than 98% of malware on our test computer.

Even though Malwarebytes provides a very strong malware detection engine and techniques, we do not know how it would be rated by independent testing labs, in this case, Avast is a winner.

Final thoughts

According to our test, Avast demonstrates better performance and lower impact on a system. It also includes wide additional security, privacy, and performance feature selection, such as VPN, CleanUp and others.
