I have reported about the similar problem on the 14 of November 2014 (!):

- Any unknown program runs without restrictions when it is executed via this browser.
- Even a known virus becomes trusted when it is downloaded via Opera.

I have proposed a way to solution of this problem on the 14 of November 2014:
Please, add ability to disable automatic detection of trusted installers!
