1. Preface:

The harm of Trojan horse is that it can control your computer remotely. When you become a "chicken", others (control) can enter your computer, peep your files, steal passwords, and even use your QQ to send some messy things to your friends ...

Trojans appear in large numbers, in that it has a direct commercial interest. Once your online banking password is stolen, it's too late to cry. Because of this, now the more the Trojans multiply, a great "wild fire endless" potential. Trojan and virus cooperate with each other, the harm is more and more big. It is no exaggeration to say: Trojan is from the network cable into your home thieves robber. Anti-Kill Trojan, has become a compulsory course for modern computer users.

2. Principle:

Trojan Hazard, although a variety of means, but ça, the necessary step is to establish an administrator user in your system. This article is to start from this link, to prevent Trojans to establish users. In this way, even if your computer has been infected with Trojans, but because the user can not build, Trojan can not play the function of remote control. In other words, it is to waste it, make him into rubbish. Of course, rubbish also needs to be cleaned up, but this is no longer covered in this article.

3. Methods:

Run Regedt32.exe open your registry, which has a directory tree:

Open Directory HKEY_LOCAL_MACHINE

Then open the directory SAM

Then open the directory SAM

Then open the directory Domains

Open Directory Account

Then open the directory Groups

Well, that's the Groups is responsible for creating users. (Note that before you take the next step, you need to back up the groups and, if necessary, restore it.) Delete it, the system can not create users. No matter how the Trojan toss, can not build users, not to mention promoted to administrators. If the file in this directory is deleted, there is no way to restore it.

Backup method: Right click Groups Select "Export", give the exported file a name, save, it is OK.

4. Description:

Maybe when you go into the registry, you can only see the first SAM directory, and the rest of the list is not visible. Don't worry, that's because you have insufficient permissions, right click on the directory to select "Permissions", you (usually Administrators) set to "Allow Full Control" on it. And so on, until you find the Groups directory.

5. Restore:

It's easy to find the file you exported, just click on it.

Since you have deleted the Groups directory, you will not be able to use the "user accounts" and "Local Users and Groups" features in Control Panel, so backing up your files is important. When you need to use the corresponding function, first restore, as before. Of course, if you are a personal user, you always use the computer alone, it doesn't matter.
