The "Virtual USB Multikey" is a software tool that creates a virtual copy of a physical hardware key (often called a USB dongle or "key"). It's primarily used to simulate the licensing environment for critical software, especially in industrial sectors like professional CAD, manufacturing automation, and certain legacy systems. It operates as a in Windows, running at the system's core level (Ring 0) to create a logical "pseudo-device" that behaves exactly like a physical USB security key to the operating system.

No, not technically. The .sys file itself is a driver. However, because it is often used to bypass security, it is frequently flagged as a "hacktool" or "riskware" by antivirus software. Legitimate security software is correct to flag it, as it is a tool that can be used for malicious purposes. The .sys file itself may not be a virus, but the download source very likely bundles it with actual malware.
