It claimed Microsoft wasn't giving them enough time to adapt their products to Windows updates and hindered the ability to download or renew third-party security programs.
Kaspersky first filed an antitrust complaint against Microsoft in its native Russian Federation last November, followed by complaints to the European Commission and the German Federal Cartel Office in July. Now in a new development, the company has announced it would be dropping its complaint in all territories following changes Microsoft introduced in the Fall Creators Update to address their concerns.
The crux of the matter is the way in which Microsoft issues security updates in Windows 10, an operating system that has Microsoft's own antivirus service, Windows Defender, built into it. Kaspersky Lab took issue with Microsoft's updates disabling "incompatible" security software, after third-party security developers had only one week in which to prepare for upcoming updates.
Antivirus maker Kaspersky Lab has just dropped its European antitrust complaint against Microsoft after the Redmond firm agreed to make changes in the Windows 10 Fall Creators Update. They also complained that Windows 10 updates sometimes cause Kaspersky to disappear from users' PCs.
If an anti-virus application's license expires, instead of showing a toast notification that may be ignored by the user, a new persistent notification will be visible on the screen that will remain until the user decides to renew their license or choose to transition to Windows Defender or another third-party solution.
"We believe in a healthy antivirus ecosystem working with us in protecting our shared customers from security threats", wrote Rob Lefferts, partner director of Microsoft's Windows enterprise and security division. Microsoft is also changing the way Windows 10 informs users when an antivirus application has expired. Windows 10 then automatically turn on Windows Defender, claiming that the Kaspersky antivirus "doesn't work on this version of Windows". The changes will affect Windows updates released globally. The changes have however mollified the company and avoid unpredictable results from the various antitrust committees in the various jurisdictions.
Russia's Federal Antimonopoly service said in November 2016 that it had opened a case against Microsoft over an alleged abuse of market dominance.
Russian security company Kaspersky has filed a fresh official antitrust complaint with the European Commission and Germany's Federal Cartel Office, alleging that Redmond is using Windows' substantial install base to promote its own security products over those of competitors. "The company is satisfied with the proposed approach by Microsoft to address the warnings issued by the FAS, and its implementation road map. They'd love nothing more than to be able to concentrate on trying to out-smart the single security solution of a monopolist".
