What is alarming is that its almost as its a real application being installed , and you can't detect that you are already compromise, feature is Keylog, fake login, steals login said that can also detects when a user is logging in, screenshot, which we have no idea it is happening, hope that antivirus company will be able to stop this kind of malwares, like the others but, to make sure everyone is safe don't just install applications, or click pop-up, emails because they are where everything starts simple click can flush everything.
The fact that some specific anti virus can detect it, it's no longer a secret who also manufacture these viruses. But anyway, if antivirus won't be enough to detect these malwares. It's best to be yourself as the actual guy to prevent it from happening and that's why refraining in downloading unknown apps that you don't actually need to have. Awareness is the best anti virus and if someone is having hard time detecting which one to download, better not to touch it without any verification if it's the actual app you need or not.
