The people behind the popular Kaspersky security software are accusing Microsoft of purposefully disabling third-party security software. Kaspersky Labs has taken its complaints to the European Commission.  The issue stems from what happens when users update to a newer build of Windows 10. Sometimes, when there’s a major update like the Anniversary Update, Windows will uninstall third-party software that isn’t compatible with the new version of Windows and activate Windows 10’s built-in Windows Defender.


Folks who are helping to test drive Windows the upcoming Windows Creators Update had that happen this spring.  Microsoft says it works hard with all third-party security vendors to make sure they are compatible with the latest updates and that 95% of antivirus applications had no issue with that new build for the creator’s update.


According to Microsoft, the antivirus apps that were disabled were only disabled to allow them to update to a newer version that would be compatible with the latest version of Windows. Rob Lefferts, a director in the Windows Security & Enterprise division said,  “For the small number of applications that still needed updating, we built a feature just for AV apps that would prompt the customer to install a new version of their AV app right after the update completed. To do this, we first temporarily disabled some parts of the AV software when the update began. We did this work in partnership with the AV partner to specify which versions of their software are compatible and where to direct customers after updating. ”

He also pointed out that Windows encourages customers to stay secure and even reminds them when third-party security subscriptions are going to expire and makes no move to activate Windows Defender unless the subscription has already expired.

The folks at Kaspersky say Microsoft is trying to promote what Kaspersky considers an inferior product and that Microsoft doesn’t give Antivirus companies enough times to make their products compatible.
