How to delete indicator (NOT custom) from entire MT4 platform?

 
Hello, I don't know how to permanently delete indicator from MT4 software? Indicator, in my case Average True Range, is original one and NOT a custom. I would like to delete it from menu so from entire Metatrader software and not only from chart. This indicator is worst one ever seen - impossible to trade according to it, impossible to follow it, wrong data, no signals where to enter Short/Long online, no resources about this indicator, nothing. I would like to get rid of it but how do I delete it? Its not a custom one so I need help getting rid of it. Thanks in advance.
 
  1. Not possible
  2. Why is it "worst one ever seen?" It is the simple average of the last n bars of True Range, of average bar hight. Nothing more. Why do you think the measurement is wrong? It doesn't generate signals. It doesn't signal direction.
  3. You can't "trade according to it," because you don't understand it verses other indicators. PICNIC
