The Scot defended the role of the Red Devils legend, maintaining that his presence at games does not have a detrimental effect on the team.
Ferguson retired at the end of last season but has since been seen in the stands at the majority of United's games this campaign - most recently alongside Sir Bobby Charlton at the 2-1 loss to Sunderland in the Capital One Cup semifinal.
Yet Moyes refused to entertain the idea that this brought added pressure on his own position, instead praising Sir Alex for the support he has afforded the former Everton boss.
"It tells you that people don't know me and don't know Sir Alex. People are saying it because they have no idea about how it works," Moyes told MUTV. "Sir Alex has been fantastic. He has been incredibly supportive and is only there to help me. I have a conversation with him when I need it and I tend to see him for a minute or two after the games.
"I have found him great and it has been the same with Sir Bobby and Bryan Robson. All the people around the club have been great as have all the former players, in the main. But there are a lot of people out there who are trying to twist the words or make out it is a problem. I have no problem with it at all."
United has lost its last three fixtures and faces a trip to Hull in the Premier League on Saturday evening.
