If you are still running Windows 7, the safest path forward is to move toward a supported operating system: Windows 10/11 Upgrade

Because V2.2.3 modifies the Master Boot Record (MBR) or the boot manager, it functions as a . Modern security tools (like Secure Boot in Windows 8, 10, and 11) treat this behavior as a malicious rootkit. In fact, many real viruses—like the TDSS and Pihar rootkits—use the exact same technique to hide from antivirus software.

To understand the loader, one must first understand OEM activation. Genuine OEM computers come with a certificate (the OEM’s digital signature) and a corresponding OEM product key embedded in the BIOS’s SLIC table. When Windows 7 boots, it checks the BIOS SLIC against the certificate and key installed in the OS. If they match, Windows is activated silently.
