QQPCRTP.exe is a process that uses QQ Manager. Task Manager cannot turn it off. 360 Process Manager cannot turn it off either.
Use Wsyscheck to kill all processes instantly. Just right-click and it's done.
Wsyscheck is not just a process manager. It's not that simple.

Use it in detail and experience it yourself.
