The first thing a malware will do on your computer is that it will disable the task manager. Now you can’t see the list of malicious processes since you can’t even open the task manager. You press ctrl+alt+delete and nothing happens, what to do now?
Well, don’t panic. Go to Start>Run and copy-paste the following into it, and press enter,
REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableTaskMgr /t REG_DWORD /d 0 /f
Go to Start>Run again, copy-paste the following command in the text box, and press enter,
REG add HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableTaskMgr /t REG_DWORD /d 0 /f
Repeat the process again with the following command,
REG add HKEY_USERS\.default\Microsoft\Windows\CurrentVersion\Policies\System /v DisableTaskMgr /t REG_DWORD /d 0 /f
Note – If while using the above method, you get the error message that “Registry editing has been disabled by your administrator”. This means that the malware on your computer has disabled the registry editor as well. To enable the registry editor again, follow the steps mentioned in this article.
