The Group Policy is changed to the open mode for Troubleshooting Instances.

This article uses an example to describe the TrojanGroup PolicyThe solution is as follows.

Yesterday, there was a trojan in the computer. The reason is unknown because the computer in the unit often plugged in or out the USB flash disk. It is estimated that it is a virus caused by the USB flash disk, but the strange thing is that my 360 and QQ doctors have enabled the USB flash drive immune function. Why didn't they detect it and stop it in time.

The specific symptom is that the input method icon is missing, the System Configuration Utility cannot be opened, and the group policy cannot be opened ......... Haha, you can only scan and kill. Although one-click restoration can be performed, the system starts to scan and kill when it wants to kill and play. First use 360 and stubborn Trojan scan to kill, but it still exists after restart. So I went to the security mode to kill and killed some of them, but I still indicated that they existed. So I saw that 360 provided NOD32 for free for six months. So I downloaded a package and started to kill it, this NOD32 is really a good guy. With the elimination of viruses, after all the scanning and removal, restart the computer, the input method icon appears, and the System Configuration Utility is opened, however, when you try to open the Group Policy, an open method is displayed, which is definitely caused by an incorrect file association method. As a result, I searched for answers in hundreds of times and found some answers, but they could not solve the problem after trying. No way. Calm down and think about it carefully. You should decide to solve it yourself. After all, I still understand computer knowledge.

The simplest way to associate a file is to right-click "open mode", but we all know that the "Group Policy" is opened by the MMC program, it is a console for controlling general files of a system. But it does not exist in the program list. Knowing that the program must have been modified by the virus, open "my computer" and click "Tools"

Click "Folder Options" and click "file type" on the pop-up page ",

Find the Microsoft general management document with the. msc extension in "registered file type" and view the "details" below,

The opening method is actually an "Unknown program". In fact, it is neither unknown nor a virus program. Of course, after virus detection and removal, the program can no longer be opened, A "Restore" button is displayed below, so click. The opening method is displayed as "MMC" immediately. If you know it is successful, exit, click "start", and click "run ", enter "gpedit. msc ", the Group Policy editing box is displayed immediately. Haha, it's a bit excited, but I think of other extensions. msc file. Then, go to "Control Panel" again, click "Management Tools", and click each unit in turn,

However, it is found that the "running mode" is run, and the first one is "running mode" by right-clicking. This is obviously because the startup Item and path have been modified by the virus. Then, enter the previous interface again. In the opening method of the detailed information, the "Restore" button is changed to the "advanced" button, and click open, the virus path C: \ WINDOWS \ Fonts \ Fonts.exe is displayed in the opened Application Path. Therefore, check the path of the running method below. The correct path is displayed here: c: \ WINDOWS \ system32 \ mmc.exe "% 1" % *, copy and paste the post into the edit box of the open mode,

Set "open" to "set as default", save and exit,

Go to the management tool and click it. Everything is back to normal. Now, all the systems are back to normal.

The above ideas can be applied to other similar problems. If one day you find that a certain type of documents cannot be opened, you can follow these ideas.

The cause of these symptoms is that the virus modifies the corresponding file path, in order to damage the way users solve the problem. When we find that some functions cannot be opened, it is actually a virus. As long as we have the relevant knowledge, we can easily cope with it. Of course, for most common users, it is essential to back up the system in time, which saves you the trouble of reinstalling the system.

It is hoped that the solution to turning group policy into open mode will be helpful to readers. When we encounter problems with our computers, we should try to solve the problem by ourselves, maybe we can avoid the trouble of reinstalling the system.
