Hello,
Our engineering team in partnership with Kaspersky is currently actively working on the support of Windows 8.1.
We do not have any ETA yet as we are in the process of testing it internally before the final approval for release, however I can safely say it will be release in February.
I would highly recommend you subscribing to the following document, we will update it as soon as we official information to share with our customers:
