How resolve popup claiming to be from mac-protection.com with error code WBACK7917?
On Macbook Air, with OSX v10.7.5, while using Safari, got a popup which locked up use of Safari. The popup claimed to be from mac-protection.com. Said it was a critical security warning. Instructed to call "support" at 1-855-462-1908 and to provide error code WBACK7917. After a hard reboot the popup returned when I tried to re-use Safari.
What is this and how do I get rid of it?
Thanks,
Bob
