If you download the mod from the above thread it does work well if someone wants to manually tinker with it, and changes the permissions in a file manager by visiting the ..\World_of_Tanks\res\cef\ folder, look for the file called 'cef_browser_process.exe', do a right click for properties on it, change to Security tab, and change the user groups file permission to DENY on 'read and execute'.
I know this is not a workaround which Aslain should provide, actually, noone has to provide it, but if you wanna mess around on your own, it does work.
Also, in case you have Malwarebytes installed, it is automatically filtering the connection attempts of this shiet.
