I remember having this fake AntiVirus....(True Story)

Mine was 10x worse than yours. I believe you got lucky. For the oddest of reasons, I couldn't do System Restore. When I did get the ability, I did it. The weird thing is: The virus didn't go away. So I went and used Malware Bytes and it still didn't work. It wouldn't let me open anything but Malware Bytes, which found malware on Full Scan every time I scanned it, like as if it was copying itself. So it ended up blue screening and now it's repaired thanks to college students.
