Yes! Apple has updated XProtect to guard against OSX.Trojan.Eleanor.A.
XProtect is Apple's built-in anti-malware system. It was first integrated into OS X 10.7 Snow Leopard and is regularly and automatically updated over the Internet.
Apple has been a bit slow updating XProtect to ward off evil adware. But, with nagging from the field, Apple eventually catches up. Alongside Eleanor, Apple has also provided protection against the adware OSX.Hmining.A.2
Grateful thanks to my right-hand Mac security pal Al Varnell for helping out, as ever!
