Method 1: Use the Group Policy Editor to set the forbidden access to the Task Manager.

First log in to the system with the administrator account, and then enter "Gpedit.msc" in the start menu to open the Group Policy Editor. Find "User Settings \ Management Templates \ System \Ctrl+Alt+Del Options" in the Group Policy Editor.

Double-click Delete Task Manager on the right to open the Delete Task Manager property setting page, as shown in Figure 2. Select "Enable" and click "OK", then you can't use "Ctrl+Alt+Del" to open the task manager.

Method 2: Use user restrictions to prohibit access to the Task Manager.

Although the above method can prohibit access to the task manager, this method does not prohibit users from directly clicking to open the task manager. If you can't use the key combination of "Ctrl+Alt+Del" to open the task manager, it will also cause inconvenience to our normal use.

The following describes the method of using user restrictions to prohibit unauthorized users from accessing the task manager. Find "TaskMgr.exe" in the "System32" directory of the system installation directory, and right-click and select "Run Mode".

Select the following users, and then enter the user name and password. You can set the above users to run Task Manager. One thing to note is that the user name and password at the administrator level should be used.

If you are suspected of being hacked after being infected by the virus, the friend above said that if possible, it is best to add the administrator password in the control panel, that is, the password of the administrator account. If not, it is recommended to redo the system and don't forget to add a password to the administrator.
