This is a false positive due to the way vorpX works (hooking into other programs). AV programs for the most part just guess. They rely on checking what a program does and if they find something they dislike, like hooking into other programs, they claim to have found something malicious, unfortunately most of the time without telling their users that they are actually just guessing.
If you happen to use a third party AV program the best you can do is switching to Windows Defender. Happens with Windows Defender too occasionally after an update, but unlike others at least Microsoft is quite fast fixing such problems.
Alternatively report this as a false positive to your AV vendor so they can fix the problem.
Also makes sense to exclude the vorpX program folder (typically C:\Program Files (x86)\Animation Labs\vorpX) from your AV scanner.
Thanks for the explanation Ralf. I use windows defender and I’m always up to date with updates so I don’t know why we (OP and I) both got this message and everyone else didn’t. Maybe they haven’t updated yet. :D
