When a good and powerful virus infects a computer, most likely it will disable you from running Task Manager (taskmgr.exe), Registry Editor (regedit.exe), Command Prompt (cmd.exe), System Configuration Utility (msconfig.exe), configuring Folder Options and hide the Run from Start Menu. Reason the virus does that is because most of the time it is “possible” for computer experts to remove the virus by using the built-in Windows programs without any third party tools.
It is easy to re-enable all those tools back by modifying some values in your registry but if the virus is still active in your computer, the restrictions will be restored back. So for emergency cases, here are some replacement tools you can use to replace the disabled Windows tools. Link : Download This E-Book Password (for rar file) : kurdsportal.com
But if you can’t run Task Manager, you cannot end the suspicious process. You could use the taskkill command in command prompt to kill the process but again you won’t be able to do that if CMD has been disabled. Perhaps you can run msconfig to stop the virus from auto startup but also cannot because of the virus. For advance computer users who has knowledge in registry and thought that they could manually remove the virus auto startup entries there, they too can’t do anything about it if regedit has been disabled. Disabling of Folder Options is to stop you from setting your computer to display hidden and system files. This way you can’t see the virus file and hence you won’t be able to delete them.
