Kaspersky Lab and Microsoft simultaneously announced that they've reached common ground on an antitrust complaint the antivirus vendor filed with Russian and European authorities in late 2016 and mid-2017, respectively.
"Kaspersky Lab confirms that all of its concerns regarding the unfair competition law [...] have been addressed," wrote the company in a press release yesterday.
The antivirus vendor also added it would be taking all the steps to withdraw its complaint from both Russian and EU probing bodies.
Last year, Kaspersky Lab founder Eugene Kaspersky accused Microsoft of using its control over the Windows operating system to push its own anti-malware solution — Windows Defender — on the detriment of third-party software.
Kaspersky accused Microsoft of burying license expiration notifications, quietly deactivating third-party antivirus products, and automatically turning on Windows Defender instead.
In addition, Kaspersky also accused Microsoft of giving third-party AV vendors little time to prepare for new Windows versions, turning off incompatible products, and enabling Windows Defender instead.
Another gripe was that when users activated Windows Defender, Microsoft quietly killed the third-party AV, with almost no visible warning.
A resolution to all the complaints came after Microsoft agreed to play nice with third-party antivirus vendors. In a statement released yesterday, Microsoft announced changes to the way it treats third-party antivirus software on Windows 10 and a change in the relationship between the company and third-party antivirus vendors.
Microsoft said the changes in how Windows 10 interacts with third-party antivirus software will go live with the release of the Windows 10 Fall Creators Update, scheduled for October or November this year.
