50 TECH ADVISOR • MARCH 2020SECURITY SPECIAL
As for the testing
houses, AV-Test gave
Windows Defender (the
AV portion of Windows
Security) a 100 percent
score for both its 0-day
and prevalent malware
tests, using 368 samples
and 13,000 samples,
respectively. The testing
period covered July and
August 2019.
AV-Comparatives also
gave Windows Defender a high rating. In its real-world
protection test for July and August, using 352 samples,
Windows Defender blocked 100 percent of the threats.
That’s fantastic, but Windows Defender also had the
highest false positives rate at 39.
AV-Comparatives’ malware protection test from
September 2019 was a mixed bag. In that test of
more than 10,000 samples, Windows Defender had
a 29.7 percent offline detection rate, which is terrible
and the second lowest. The online detection rate was
the absolute lowest at 76.3 percent, whereas most
security suites are hitting around 97 to 99 percent. The
online protection rate, however, was very high at 99.96
percent. There were 13 false alarms, which is a mid-
range result.
Finally, we looked at SE Labs, which gave Windows
Defender a AAA rating. SE Labs put Microsoft in the
second tier of AAA products along with ESET and
McAfee, all of which missed one public threat, butA malicious file
