Hacktool:Win32/Keygen and its Risks
The tool itself is not harmful, but Hacktool:Win32/Keygen is often delivered together with malware. The tool allows users to "crack" (illegally register) various software. It forges activation keys/license files to trick programs into believing that they are activated.
AutoKMS and Hacktool Agent
AutoKMS is a hack tool downloaded intentionally by most users who try to activate unregistered Microsoft products. HackTool.Agent is a generic detection for tools used to gain unauthorized access.
Safety Concerns and Removal
It’s just an activation service to activate Windows 8/8.1/10 (illegally). Antivirus programs may show it as malicious since it modifies system files. While KMSAuto Net may have safe copies, there are many versions carrying malware.
If you want to remove hacktool from your laptop, you can try uninstalling it like any other application. Another option is to use Windows 10 built-in security feature for removal.
