There are bad areas everywhere in every city believe it or not! What I would recommend is to contact the police department up there. You could try and drive around and see what areas you like and narrow them down and then call the police department. I would also ask the neighbors of those areas because they will be honest. If you see someone out walking, washing their cars etc, I would stop and ask them about the areas. You could drive around at different times of the day as well because different areas become much different during day and night. I am confident if you take my advice, you will find a place you are comfortable with. Get a good agent up in that area. I have several I could refer you to if you would like. And ask them as well. Adelanto is out of the area I typically work in and I don't know what areas are best myself. But, I can put you in good hands to find what you are looking for. You can email me at firstname.lastname@example.org and I will help you with that if you would like!
