MOSCOW, November 21 (RAPSI) - The Russian Federal Antimonopoly Service (FAS) set December 20 as the date for hearing a case against U.S. IT giant Microsoft over alleged abuse of its market dominance, RIA Novosti reports Monday.

In mid-November, the FAS initiated a probe into Microsoft upon a petition lodged by Kaspersky Lab cybersecurity company. Kaspersky Lab complained that the U.S. company had significantly cut the time which third-party developers of antivirus products should ensure compatibility of their software with Windows 10, from 2 months to 6 calendar days.

Due to the fact that Microsoft itself is a developer of antivirus software Windows Defender, which automatically launches if third-party software had no time to adapt to Windows 10, this decision results in unjustified advantages for Microsoft on the software market, Anatoly Golomolzin, deputy FAS head, commented on the probe adding that the FAS priority was to ensure equal conditions for all participants of this market.

Kaspersky Lab earlier reported its intention to file a similar complaint against Microsoft with the European Commission.
