I'm not worried m8, that will not be on my system or any system I control... my why was more a "why use regedit instead of some other software?" regedit isn't for making software runs... group policy or image software are better for pushing a program out to a workgroup of computers because they are designed to do this.
Any Microsoft product will treat a regedit file as suspicious so you will have to;
1. Override it as policy, which is a bad idiom because that opens the door to all kinds of other regedit attacks or
2. Train your people to say yes repeatedly to "are you sure you want to do that" messages which IMO is almost as bad or
3. Use some other software that is made for this kind of thing and doesn't send up so many red flags...
