A counterfeit version of the Flyoobe tool, which helps install Windows 11 on unsupported devices, is circulating and may contain malware. The official developer warns users to download Flyoobe only from the official GitHub page to avoid risks. Reports indicate that malicious updates have been released through a seemingly legitimate domain. Users are advised against engaging with third-party tools, as they can cause critical issues, including potentially "bricking" devices. Microsoft's Extended Security Updates (ESU) program is available, but critics view it as a temporary solution. Microsoft claims that Windows 11 PCs are significantly faster than Windows 10 PCs, and as support for Windows 10 ends, the use of tools like Flyoobe is expected to rise, along with associated risks.
