Trackpad/Touchpad acting erratically

I recently purchased a MBP in the end of July. Recently the trackpad/touchpad (whatever you want to call it) has been acting erratically. The mouse will move all over the screen, click on what it wants, right-click on what it wants, zoom in/out on what it wants, and has even been making tons of new folders on my desktop because of it's ability to left and right click randomly. When I try and move the mouse by using the trackpad, it simply freaks out and will not move the direction that I want it to. Any insight onto what the deal is? This started happening a few days after a software update.
