clean uninstall and reinstall

[David198502]

hey guys!i want to do a complete clean reinstall of cod.meaning i want to uninstall it completely and then do a clean reinstall.
i did it today, but somehow my game stutters and freezes more than with my previous install, so i want to do it correctly.

i want that nothing is left on my pc from cod before i install it again, to prevent it of using old possible corrupt files.
so what else should i consider to do besides deleting it from steam?
thx in advance.
