My PC is running Window 10 for a year. It was installed with Panda antivirus and running well. Recently I’ve installed Malwarebyte antivirus, and when I update the this antivirus, the system cannot shut down. I need to long press the on/off button. After restart, same problem occurs. When I press the window 10 button (on bottom left), the system hangs, but I can get the right click menu, and go to the control panel. However, most of the system tasks cannot be run, eg taskmanager, regedit, uninstall the program, troubleshooting, windows update etc. And I can’t even launching Safe mode, as it won’t shout down properly. I’ve searched the forum, but nothing helps as most the steps cannot be run in my PC. Any suggestion?
My PC is restored to normal, but not by re-installation of the Window. When I want to perform the reinstall, the PC prompted that the free trial period of Malwarebyte antivirus was expired. My PC still hang by running certain function. However, after a few re-start, Window defender asked me whether I'd like to remove the Malwarebyte antivirus. I then clicked yes, and the software was removed successfully. Thereafter, my Window run normally, and there is no need to reinstall. Hence, if anyone have the same problem with Malwarebyte antivirus again, and can wait, upon the free trial period, the system may be able to recover by itself. Thanks for all the advice.
