Hello everyone.

Recently, I have compiled my own standalone application using Matlab Compiler – let’s say it is called JHApp.exe. Then, I tried to test the functions of my JHApp.exe file occurring in the for_redistribution_files_only folder (i.e., without installation). During each very first run (with each new compiled version), a security alert is reported by Avast. I understand the antivirus is suspicious of that new executable file and I know this is quite common – this is not the major problem.

However, after several minutes of using JHApp.exe (the app makes many calculations and can create .xls, .html and .m files), I received a new, more specific alert, something like IDP.ALEXA.54 detected, and Avast moved JHApp.exe to the carantine.

Given that I have spent a lot of time coding the app and I want to share my app in a scientific community, it is very important for me that it is trustworthy and safe. May it happen that a harmful code, e.g., from an infected PC, is accidentally and unintentionally distributed together with a Matlab standalone application?

It is quite strange for me to imagine that – my PC does not seem to be infected (according to Avast), and I don’t think some harmful code can easily attack Matlab and hide in a standalone application.

Please, what do you think about that?

Thank you very much for your answers.
