Application of ill repute; & what is the best Settings configuration of Sophos Mobile Security

Good morning to all,

I need an advice about “Application of ill repute/Application with bad reputation/” detected by Sophos Mobile Security

I am wondering how it comes that Sophos Mobile Security detect a pre-installed application in my phone as “Application of ill repute/Application with bad reputation”? First, what could affect in the system; does it may include a virus, Trojan, malware? And is it better that I avoid to install any application detected by Sophos Mobile Security as “Application with bad reputation”? ; Or only the PUA will have a dangerous damage for the mobile system?

In addition to that, could you please help me to set the best or tell me the right way for settings configuration (what I have to check, what I should leave unchecked).

Thanks in advance.

Kind regards,
