Kingsoft PC Doctor is a software program developed by Kingsoft Security. During setup, the program creates a startup registration point in Windows in order to automatically start when any user boots the PC. Upon being installed, the software adds a Windows Service which is designed to run continuously in the background. Manually stopping the service has been seen to cause the program to stop functing properly. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). When installed, it will add a context menu handler to the Windows shell in order to provide quick access to the program. The primary executable is named ksafe.exe. The setup package generally installs about 56 files and is usually about 15.9 MB (16,669,554 bytes). Relative to the overall usage of users who have this installed on their PCs, most are running Windows 7 (SP1) and Windows 10. While about 39% of users of Kingsoft PC Doctor come from the United States, it is also popular in Canada and United Kingdom.
