Do you like to be a riding steed? That is a rhetorical question.
What does the notification with HackTool:Win64/ProductKey.G!MSR detection mean?
The HackTool:Win64/ProductKey.G!MSR detection you can see in the lower right corner is demonstrated to you by Microsoft Defender. That anti-malware software is quite OK at scanning, however, prone to be basically unstable. It is prone to malware attacks, it has a glitchy interface and bugged malware removal capabilities. Thus, the pop-up which states about the ProductKey.G!MSR is just an alert that Defender has detected it. To remove it, you will likely need to use another anti-malware program.
