This copy protection software, it encrypts the program code. So some antiviruses can take it as a virus, but most popular antiviruses don't find the virus. Protector isn't written by me, I bought software for protection. Therefore, I can't change anything inside it.

Polybrush don't gather any information and don't send anything to web.
If antivirus don't let run Polybrush or delete it, only solution is to add Polybrush the exceptions.

I tried to protect other programs, even utilities from windows\sistem32 at licence windows. After protection some antiviruses found viruses inside them. In any case you can add Polybrush to exceptions and see that antivirus willn't notice any activity and infecting other files.

Apply "normals" modifier after if changing the "file settings" did not help
