System Diagnostic Removal Guide

System Diagnostic Removal Guide
System Diagnostic is a fake optimization tool which claims that it can optimize the performance of the hard drive, memory and the system of computer. However, the fact is that System Diagnostic cannot optimize the performance of computer, but will definitely scare the user with a lot of fake warning by showing pop ups which states that the hard drive, memory and system have a lot of errors. Do not believe any report given by System Diagnostic as it can do nothing but just try to urge the user to buy the full version of System Diagnostic to remove all the detected errors. Full version or unregistered version of System Diagnostic can do nothing.

System Diagnostic can be removed by stopping and removing all the processes and files with random name in the hard drive and restoring the registry entries added and modified by System Diagnostic. All of them has been shown in the removal guide below.

System Diagnostic should be removed immediately!
