Kaspersky withdraws Windows 10 antivirus antitrust action against Microsoft

Kaspersky, maker of the popular Kaspersky Lab antivirus suite, hit Microsoft with a legal complaint in June, claiming that the company used unfair practices to promote Windows Defender over competing products in Windows 10. At the time, Kaspersky accused Microsoft of removing its software from users' PCs when they upgraded to Windows 10, turning to Windows Defender in its place. Microsoft said that was for compatibility issues, but Kaspersky said the company didn't afford third-party antivirus developers enough time with an update to prepare its software ahead of a broad rollout.

The best antivirus software of 2017

Yesterday, Microsoft announced changes that address Kaspersky's complaints. And they appear to have appeased the Russian antivirus company, because today it responded with a blog post stating that it will withdraw its legal action (opens in new tab) against Microsoft.

BitDefender

Here's a list of changes Microsoft promised:

  • It will work with antivirus vendors more closely on compatibility before major Windows updates.
  • It will give antivirus vendors more time in advance of major OS updates to prepare their products and provide more clarity on specific release dates.
  • The company will let third-party antivirus vendors use their alerts to tell users that their antivirus will soon expire, and notify them if the software has already expired, so they can update and stay secure.
  • Windows itself will also let users know if an antivirus program is no longer active. A new notification will remain on the user's screen until they either renew the third-party software, or they pick another option, such as Windows Defender or another third-party antivirus. (Currently, a toast notification lets users know their antivirus is about to expire but it quickly disappears and is easily missed.)

These changes can be expected in the Windows 10 Fall Creators Update, according to Microsoft.

From Kaspersky:

We are absolutely satisfied with the changes that will be implemented in the Windows 10 Fall Creators Update, and we will be taking all necessary steps to withdraw our claims and inform all regulatory bodies that we no longer have any matters for Microsoft to address.

  • Maybe they should have contacted Microsoft in the first place before submitting a complain.
  • They should use feedback hub like many others..... If Microsoft responds with enough upvotes
  • Or they could join the Insider programme? They'd have access to new builds and have plenty of time to prepare their software
  • "Russian infosecurity" is a contradiction in terms surely?
  • Yeah, Putin must have been behind this.
  • Or you could blame Trump. Every tool on the planet tries attaching everything going on to him...
  • Or...these companies could've been using the preview rings...
  • Not just antivirus... every software dev should work closely with every OS maker (Android, Mac, iOS, not just Windows), pay attention to those "deprecated" function calls...
  • Good move on Kaspersky and a better move on Microsoft. Kudo to both...Russian business is lucrative!
  • Did... Did something between companies get handled maturely? Is this the end times?
