    Why Windows Defender is not ranked higher in new AV tests

    Microsoft's Windows Defender ranks seventh out of 15 antivirus (AV) products in an independent test. But the results don't tell the whole picture, argues Microsoft.With improvements to Windows 10's built-in Windows Defender antivirus, some users are questioning whether it's worth paying for a third-party product from the likes of Symantec, McAfee or Kaspersky.

    But according to the latest results for Windows home and business use from German AV benchmarking firm, AV-Test, Windows Defender is still trailing third-party AV, tying in seventh place with four other vendors.

    The top AV products for Windows 10 across protection, performance, and usability in December were Trend Micro, Vipre, AhnLab, Avira, Bitdefender, Kaspersky, and McAfee, according to AV-Test.

    Windows Defender rated highly on protection, detecting 100 percent of new and old malware, but lost points for performance, which measures how much an AV slows applications and websites; and usability, which counts false-positives or instances where AV wrongly identifies a file as malicious.

    Windows Defender's performance rating was dragged down because it slowed the installation of frequently used applications more than the industry average, and wrongly detected 16 pieces of legitimate software compared with the industry average of four.

    But Microsoft wants enterprise customers to know that Windows Defender is only half the picture, given the option for customers to also deploy Windows Defender Advanced Threat Protection's (ATP) "stack components" including Smartscreen, Application Guard, and Application Control.

    In the January and February test Windows Defender also scored 100 percent on protection. However it did miss two samples. Since then it's retrained its machine-learning classifiers to detect them.
    But Microsoft notes in a new paper that Defender ATP did catch them, which isn't reflected in AV-Test's or other testing firms' result. Microsoft hopes to change this so that testers include so-called stack components available in ATP.

    I am more inclined to believe that the people who designed the product are best qualified in how best to protect it.....and of course with this new direction taken by M$ AV wise, they have a reputation to make....this will worry the AV industry.

    Paid for AV products for fiscal reasons especially in computer magazines with their advertising revenue tied in will always get a higher rating.

    In the AV Test Kasperski came out top in the ratings, I note in America they have banned it in all official government much for its high rating.

    ESET Smart Security is my main security program. IMHO MS can't release a update without causing problems for many Window users. Their UUP is a joke. They never got the bugs in Internet Explorer fixed so they pushed it aside and are trying again with Edge. There's no way I'm going to trust them to have a #1 security program.
