Master tricks to repair Windows 7 can not open the task manager [map]

The registry, the task manager can't be opened, or the hard disk is occupied for no reason. After killing the Trojan with killing software, only the task manager can't open. The phenomenon is that the appearance of the pop-up manager disappears immediately. But the mouse only flashes gently and nothing happens. The specific symptoms are as follows:

Setting the task manager with regedit or Gpedit.msc is invalid, copying the new taskmgr.exe to system32. The dllcache is also invalid, the same is true in the safe mode, the Windows 7 CD repair installation is invalid, the next manager on the Internet is useless.

In fact, as long as a exe file can be run normally, rename it to taskmgr.exe, it will become this phenomenon, as long as taskmgr.exe changed its name abc .exe can be run, but changing another file such as notepad.exe to taskmgr.exe will not work.

This is a typical image hijacking. The principle is that the Trojan virus has image hijacking, and many executable programs are mapped to the ntsd.exe file, so it cannot be opened. ntsd.exe is included with the Windows system. The debug command should be terminated by the virus after the virus is called. This command terminates the process. The solution is very simple, open the registry editor, then navigate to hkey_local_machineSOftwareMicrosoftWindows NTCurrentVersionImage File Execution Options, then clear all the items under Image File Execution Options and then solve the problem by downloading the latest killing and killing Trojan.
