Uninstall RAV Antivirus
Recently, if you installed NOX/Memu or auto updated, it came with RAV antivirus unfortunately. It was blocking our software. It's easy to uninstall.
Search “Control Panel” on your computer
Click “Uninstall a program”

Scroll down and look for three products by RAV:
- Two starting with RAV
- One starting as Web Safe.
Uninstall all, and you should be good!
