Problem when copying indicators and templates on MT4

[Bertraand]

Hi, I can not install other templates and indicators from the web on my MT4 platform. I specify that these files are in EX4 and MQL4 format. I followed the installation procedure by going to File / Open data folder / MQL4. I even uninstall and reinstall the app many times. I receive as error message "Blacklisted folder". Does anyone have a solution?

I seen that it`s not a MetaTrader Message window. Posiible it`s anitivirus or other malware protection software.

U should fully decribe this incident to "service desk" request for prеvent it in feuture.
