how do i optimize my pc?

if you have more than one virus detectors choose your best one and delete the other ones. then if you have websites remembering your passWords delete those (if you cant remember your passwrds than just skipp this tep...doesnt really matter if you do or dont.) then disable other add-ons like UNITY-3D and others....if that doesnt create the sped of your computer as needed then get professinal help.
