Updated June 6, 2017: Updated with a statement from Microsoft on the matter.
Original Story: Kaspersky Lab has moved to file an antitrust complaint against Microsoft in Europe over what it sees as unfair practices to promote Windows Defender over competing products in Windows 10. In a blog post, co-founder of the Russian firm, Eugene Kaspersky, lays out several complaints that, he says, highlight "questionable tactics" on Microsoft's part to give its own antivirus solution an unfair advantage (via The Verge).
Kaspersky's complaints include accusations that Microsoft removes its software from users' PCs when they upgrade to Windows 10, turning to Windows Defender in its place. The stated reason is compatibility issues, but Kaspersky claims Microsoft doesn't afford third-party antivirus developers enough time with an update's RTM release to update their software ahead of a broad rollout.
In its complaint, Kaspersky says it is seeking to stop Microsoft from "misleading and misinforming" users in order to keep security software "on a level playing field" on the Windows Platform.
For its part, a Microsoft spokesperson reached out to Windows Central with the following statement:
