• A third-party hypervisor is running (e.g. VMware). To eliminate the error, close the third-party hypervisor.
• Hardware virtualization is disabled on your computer. To eliminate the error, enable the support of hardware virtualization in the BIOS settings. See the guide for Windows 10 below.  
• Your processor does not support hardware virtualization. You can find out whether your CPU supports hardware virtualization in your computer’s technical documentation or on the vendor's site.

1. Click the settings icon in the lower-left corner of the main window of your Kaspersky Lab application. If you’re not sure how to open the application, see this article.
