Hello, A friend of mine hacked my mac. He says he can see through my webcam, he knows all my passwords (facebook, system passwords), he can see my safari history even though I always clear it. He says he uses a program called sub7 (maybe it's a lie) I install kaspersky to scan my system but it found nothing on it. The first time he did his intrusion, we were both connected to the same network. But he can yet do it from anywhere. How did he get it ? How can I remove the kind of malware he set up ? How can I prevent an other intrusion ? Can someone help me, I am really scared. I feel like everything I do on my mac is spied !
