Somewhat, but it’s not a virus. It’s contained to it’s own file system unless it does something really stupid, and I can easily remove the while whole thing. But the reason i needed it privileged is because it loads the ppp kernel module, so if you know a way to do that without privileged mode, lmk.
Don’t buy windows from eBay! You can download an iso for free from microsoft. Flash that to a USB and install it that way (or as others have suggested, just use a VM). It won’t be activated but you don’t need that for what you’re doing: https://www.microsoft.com/software-download/windows11
If you don’t need windows 11, I actually recommend 10 ltsc. It doesn’t come with all the bloat and adware that normal windows comes with: https://www.microsoft.com/en-us/evalcenter/download-windows-10-enterprise
