If, for some reason, you have to completely block an application’s access to the Internet, the best solution will be to prevent the application from being able to transfer data.
To limit any kind of network activity for an application, do the following:
- run Dr.Web;
- open the Firewall;
- click on the "Applications" tab,
- select the program whose Internet access you want to limit;
- in the newly appeared window, in the "Access to data transmission" section, disable the use of Wi-Fi, mobile Internet, and roaming for each application in the list.
