Just fixed that by : delete my gos %appdata% , totally uninstall gos with Iobit uninstaller , then i open avast antivirus ( this was the problem ) , i go to options , then i go to exclusion and i add those 3 exclusions : C:\Users\*******\Desktop\Loader(1).exe
C:\Users\*******\AppData\Roaming\GamingOnSteroids\*
Go to URLs and add this :
http://gamingonstero.../loader_files/*
Now all should be fixed
