The German test lab AV-Test compared twenty virus scanners for Windows 10, and once again, Windows Defender, the antivirus software that is built into the operating system as standard, came out of the test as “Top Product”. The test focused on antivirus packages for end-users.
The virus scanners were assessed for malware detection, performance, and usability. In total, the packages earned 18 points for all three components. Malware detection was based on some 400 “zero-day” malware samples and 20,000 malware samples discovered in the last four weeks before the test.
