Desktop Icons/Touchpad

I have an HP Pavilion g6 laptop running Windows 10. Earlier today my touchpad acted up and my curser would not respond correctly. It would barely move and jumped from place to place. The biggest problem was it resized my desktop icons to a huge size as if I had a zoom. My nanoheal corrected the problem with touchfreeze but my icon are still huge. My screen resolution is correct. I used right click to resize the icon to small but their still huge. Any ideas...
