Help! problem with touchpad Inspiron 15 3567

I have problems with an inspiron 15 3000 series I have months of having acquired it, the touch pad gives click 2 or 3 times in a row whenever I press on a link or image, and probe with the controllers but still the same, the external mouse work well but as for the touch pad remains the same. I need a solution for it, it is very frustrating every time I use the touch pad.
