I've been watching you for a few months now. The fact is that you were infected with malware through an adult site that you visited. If you are not familiar with this, I will explain. Trojan Virus gives me full access and control over a computer or other device. This means that I can see everything on your screen, turn on the camera and microphone, but you do not know about it. I also have access to all your contacts and all your correspondence. Why your antivirus did not detect malware?
