How to remove [PCOptimizer 3.0] using command prompt

You are supposed to start with all programs closed because an Explorer and Taskbar all terminate.
Run a command prompt. [Start] - [Program] - [Accessories] - [Command prompt]
* Important : In Windows Vista/7/8/10, you are advised to select [Run as Administrator] by clicking on [command prompt] using the right mouse button.

When the command prompt is run, there comes out a black screen as below and the cursor begins to flicker.
The letters or shape appearing on the screen might be slightly different, but don't bother. It'll be all right for you just to get a similar screen as below.

When you fast click the mouse button for three times in a row in the red line(command line) below, you can select all.
Then, mouseclick the selected zone and copy it. (Ctrl + c or Select a [copy] on Right-click contextmenu.)
In case all the zones are not automatically selected, you will have to copy it by dragging the whole of the red line using the mouse.

There might happen a case where files are not deleted due to the next command line(deletion) starts too quickly while terminating the process.
so you are advised to do one more [paste]at the prompt window after all command lines are run.
Once the command lines are all run, you can close the command prompt window.
