HijackThis is a program that helps to disinfect, however, it is not to make any newbie.
It is a specific tool to detect and remove spyware and hijackers stealthily installed on your computer. If you are a novice in the field, it is best to request assistance from an expert to avoid deleting important files.
It also helps speed up your PC starts by removing (manually) in the Startup List (software that is launched unnecessarily).
It allows you to quickly scan your computer to detect parameters that may have been changed by spyware, malware or other unwanted programs.
