How to uninstall combofix

While combofix is an extremely useful application, on rare occasions it can cause further problems to your PC and needs to be uninstalled. If combofix locks up, please try and let it run for an hour atleast before killing combofix.exe processes.

To kill the process, simply launch Windows task manager (ctrl + alt + del) and end the task, or right click on the task and select ‘Go to process’ and press the ‘End Process’ button. As this can often leave random executable files running we urge you to give combofix time to complete prior to aborting the process. If you do have to kill combofix using the above technique, be sure to reboot or your internet may not work!
