For users who want to get started with this new Windows, the existence of an installer that can be used alone without signing up for the Insider Preview program may seem appealing. Cyber criminals are aiming for that opportunity. Kaspersky Lab has confirmed that there are several malicious programs on the market related to Windows 11. One example is an installer file named “86307_windows 11 build 21996.1 x64 + activator.exe”.
