"Player" goes backwards but I´m not pressing the "S" Key

Hi.
So, I was trying to make the physics of my "game", but when I put my script to the character so it can move with rigidbody, it just goes backwards. If I press W it will go forward but if I press nothing it will just go backwards endlessly.
Help, I can´t find a solution for this and reinstalling Unity didn´t help me

 

Hi,

Perhaps you could increase the friction to prevent the player from sliding on steep roads.

 

Thank you, I found the solution but I don´t remember what I did

 

It maybe stopped walking when you released the "nothing key"?

 

Resist the player with any kind of obstruction or applying friction might help
