During Q2, 2020, NSS Labs performed an independent test of malware protection offered by web browsers: 32,267 discrete tests (per web browser) using 1,065 unique samples over 34 days. To protect against malware, Microsoft Edge uses Microsoft Defender SmartScreen; Google Chrome and Mozilla Firefox use the Google Safe Browsing API; and Opera uses Yandex.

The Comparative Test Reports provide detailed results including block rates for each product and data recording consistency of protection over time. As a service to the community, NSS Labs is providing these reports for free.
