Beginner learning about collisions

[Crash180]

So I spent a chunk of time today reading, watching and experimenting with collisions. It seems like what people have come up with are:                            

1. Find a similar existing collision and copy/paste the branch into your existing model and hope for the best.                                            
2. Get a copy of 3ds max 2013.                                            
3. Use this Nifskope resource posted by pepperman35.   Simple collision made in Nifskope for Fallout 4 / NifSkope Collision Tutorial - Fallout 4 and Skyrim.                                            

                                            
So I tried the OBJ import method in #3 using Eckserah’s Nifskope but Windows saw it as a threat. Is it really a threat? Is one dev version of Nifskope better than the other or more mainstream? Would it be as straightforward as exporting your Blender model as OBJ and importing into Nifskope?
