Reports had suggested that the 38-year-old midfielder has told "friends" he will be quitting the game for a second time next summer.
But Ferguson is certain that if that was the case, Scholes would have let him know.
Ferguson said: "I would be surprised if Paul had spoken to someone without speaking to me - and he hasn't - so we can dismiss that."
There have also been suggestions this could be 39-year-old Ryan Giggs' final season in the game, and that Rio Ferdinand's future at Old Trafford is uncertain.
But Ferguson said: "Ryan could play for another year or two. Rio has been terrific. The speculation comes from our policy of only giving older players one-year contracts."
