In the German independent research institute’s May/June 2019 ‘best antivirus software for Windows Home Users’ report, Windows Defender is one of four products to receive perfect 6 out of 6 scores in the protection, performance, and usability categories.
Windows Defender shared the top honors with F-Secure SAFE, Kaspersky Internet Security, and Norton Security, but Microsoft’s software has a significant advantage over those three: it comes free with Windows 10, while the others are paid-for options.
AV’s test results show that Windows Defender managed to block 100 percent of its 307-sample zero-day malware corpus and 100 percent of its 2,428-sample general test corpus.
