What insidious virus developers are! It is worth Microsoft to release the next patch to the system, and anti-virus companies to add signatures to the database, as a new misfortune already appears. What is happening is a typical eternal "dispute" of armor and shell, but everyone earns as a result. The only infringed party is the user. He really shouldn’t get used to the consequences of virus attacks - stolen logins and passwords, erased data without the possibility of recovery, lost system performance and so on. Fortunately, there are certain rules that allow you to avoid the fact of infection in principle. Well, if the trouble nevertheless happened, it remains only to restore the system to working with the usual methods.
One of the last “squeaks” of the viral fashion of recent years is the black screen displayed after loading Windows. In the current version (Windows Seven), the problem is that after a successful initial stage of loading, and then the user authorization process, a black screen appears instead of the desktop and the shortcut menu. The cause of the problem is incorrect entries in the registry keys responsible for loading the shell. The problem has several solutions, and they differ significantly. For example, if you get a black screen after loading Windows 7 (or in the previous and still popular system - Windows XP), you can do the following:
The first is to install the Black Screen Fix program. A prerequisite for the effectiveness of this program is the removal of malicious software before you even launch Black Screen Fix. For this purpose, the Drweb Cure IT utility, which has a huge anti-virus database, is recommended. You can run it from a flash drive from the task manager by successively pressing "Control, Alt, Divides."
The second, perhaps the most reliable way is to restore the system through the built-in service. It should be noted that in Windows 7, the system recovery procedure is greatly simplified . Just press F8 almost after the hard drive detection procedure - you won’t be mistaken! In this menu, select startup recovery mode. Load into it by pressing the Enter button and select the first or second item. When you select "Startup Recovery", you save a lot of time, choosing the second item "System Restore", you get a guaranteed result. After performing this procedure in the seven, the problem "after loading Windows - a black screen" will be a thing of the past. Now be more careful in your actions - use an account that has limited rights and install a good antivirus.
"Well, if the system is not 7, but XP?" - asks the conservative reader, stubbornly not wanting to demolish the beloved system, which completely suits him, and establish the "seven". Unfortunately, this happens after loading Windows XP. Black screen and that's it! Then you have to use the registry editor. Well, before that, thoroughly clean the system using the already mentioned Drweb Cure IT. Well, click on the cherished combination "Control, Alt, Divides" and get the "Task Manager" window. Then, through the file menu, select a new task by typing regedit and the main system administration tool is already running.
You need to go to HKLM and select the SOFTWARE bush. From here you should choose Microsoft and WindowsNT. Now we are looking for the Winlogon subkey in the Current Version folder, without it the system would not have booted up to the authorization window. Check the value of the Shell parameter. It should be strictly explorer, without various additions. After all, the essence of the problem is precisely in the incorrectly loaded malware, it is from here that the roots of the problem "after loading Windows - black screen" grow. It will be useful to check the value of Userinit, which is also critical for loading. That's right - userinit.exe.
It should be noted that this is not all the possible options that the insidious "infection" suggests. The task manager may also be disabled. Then the method with resetting the parameters to the correct values is unlikely to work. Have to go a little different way. We start safe mode with F8 command line support and, having booted, we give the regedit command. We sequentially go through CureIT and the registry editor, following the above recommendations, and then reboot. The problem "after loading Windows black screen" is solved! If you are an experienced PC user, it is recommended that you use Zaitsev Anti-Virus along with these programs, which allows you to remove malware as well as automatically return the registry values to the correct values.
