Kaspersky Accuses Microsoft of Unfairly Disabling Its Antivirus

Microsoft used to ship Windows without a built-in antivirus client, which seems foolishly naive in this day and age. However, the addition of Windows Defender to the operating system has caused some tension with third-party antivirus makers. Windows Defender has occasionally interfered with other antivirus apps. Kaspersky recently accused Microsoft of unfair practices for the way it deletes the company’s antivirus during Windows updates. The Russian company has now filed a number of regulatory complaints to right what it sees as a tremendous wrong.

Kaspersky began complaining about Microsoft’s activities late last year when it filed a complaint with Russia’s Federal Antimonopoly Service (FAS). Just recently, Kaspersky has made a similar filing in both the European Commission and German Federal Cartel Office.

Kaspersky’s main issue relates to the removal of Kaspersky AV during Windows updates, and that’s the subject of the official complaints. Users of Kaspersky software often see a notification after updating that explains the antivirus was removed because it’s not compatible with the new version of Windows. Thus, Windows Defender is enabled. Odds are that most people will be just fine with that and won’t bother to go hunting for an updated version of Kaspersky.
