Usages notes

Many authors make a distinction between untrust and distrust. When such a distinction is made, untrust is a lack of trust, while distrust is a belief in the malevolence of another. Thus, it is untrust when you doubt your ability to accomplish something, but distrust if you believe that someone is actively preventing you from accomplishing something.
