You use a feature in your security software to detect "possibly unwanted software". This is a list maintained by each Anti-Virus manufacturer that reports when software is installed that you may not want to use, based on their own individual (and unfortunately not always accessible to us) criteria and opinion. This also explains why one software is detected, another version may not.
The manufacturers offer this function "optionally" and thus in addition to the detection of real dangers such as viruses or Trojans.
For example, our program used the red color in error analyses to make a hint or warning character clear - just as traffic signs do. We also used terms such as "problem" or "threat" when we deemed it appropriate. Also optimizations / cleanups in general seem to be a reason for some Anti-Virus vendors to display PUA / PUP detection (Potentially Unwanted Program or Potentially Unwanted Application). We have already corrected all these points, but the software is still recognized by some vendors.
We are in contact with the manufacturers to find out what exactly still triggers this detection. Unfortunately there is no rule, every manufacturer handles this differently and individually.
Until then, you would have to define an exception in your security program for our product or for the PUA/PUP signature found so that you can still use our software. You have the option to disable detection for PUP/PUA software in general or you can define an exception for our program.
The support of the respective anti-virus manufacturer will be available to answer any questions you may have . The respective help function of the Anti-Virus-Software also provides information. In addition, we are of course also available to answer your questions.
