Remove Desk365 and System Optimizer Pro

My computer is infected with desk365 and System Optimizer Pro. who says it can solve all the computer problems for me. Should I trust it?
System Optimizer Pro is a fake optimizer program. It shows up when you launch the Windows interface and claims it can offer you a shortcut to remove all the potential threats in your computer. However, the detected result it gives is
bogus. If you believe it, it may probably compromise your privacy by logging your every step. What’s more, once installed, it injects unwanted files or programs which will consume your computer resources. You should remove it as soon as possible.
