"As you all know, things have unfortunately not worked out for me the way I would have wished at Aston Villa, and I was due to leave in the summer," said Ginola.
"But Villa have agreed to release me now and I am delighted to say that I have signed for Walter Smith.
"This move feels like a new lease of life for me. I was in danger of going a bit stale in the reserves at Villa Park.
"But now I have the chance to play Premiership football again - which for me is the best league in the world.
"I want the Everton fans to know that I shall give 100%, and I hope to excite them as much as possible," Ginola added.
"The club's first priority is to guarantee their Premiership status this season and I shall do all I can to help.
"I also hope the prospect of Ginola and Gazza excites them as much as it does me!"
Ginola became unhappy at Villa after being frozen out at Aston Villa by John Gregory, who has now left. Ginola and other signing Lee Carsley will both be available for Sunday's game against Arsenal.
