Using the framaroot is fairly easy. All you need to do is to download the Framaroot for Root and and install it on your devices, launch the application and follow onscreen instructions in order to get rooting done.
Antivirus will detect it as virus because it uses exploit to enable root on your device. Also, if you’re going to do something like rooting, you should be aware that EVERY Antivirus app will make the action as malicious.
