Is this the first time you have encountered such a problem as a windows lock screen ?. Probably many have already encountered it (including me). I propose to look at the classification of blocking the windows system and their solutions.

Before you start reading about the windows lock screen, I recommend that you read the articles:

Types of computer screen lock

Type 1 - these are banners or porn informers that appear only in the browser window. The most easily removed type. They usually impersonate additional plug-ins or add-ons for the browser. It usually looks like this.

Type 2 - these are banners that remain on the desktop after closing the browser and at the same time close most of it. But users usually still have the ability to open other programs, including Task Manager and Registry Editor.

Type 3 - this is the type of banners that is loaded after the desktop is fully loaded Windows desktop. They close almost the entire desktop, blocking the launch of the task manager, the registry editor, as well as booting into safe mode. Some varieties completely block the keyboard, providing the user with only the number keys from their "interface", and a working mouse for entering code.

Type 4 is a type of banners that is loaded before loading the Windows desktop, replacing the explorer.exe file.

Type 5 is the so-called MBR.locker, which makes changes to the Master Boot Record hard drive and, accordingly, blocking the normal boot of the OS.

How to remove the Windows screen lock

What to do if Trojan.Winlock is infected

Do not under any circumstances comply with the requirements of intruders. Know that the SMS that you send will cost not as much as it is written, but much more, and besides, they will not unlock the system for you. Tested and proven.

If possible, use online services for selecting an unlock code on the websites of anti-virus software manufacturers (Dr.Web, Kaspersky Lab).

Perform a full scan of the computer with an anti-virus utility with the latest updates to the anti-virus database (for example, the “one-time” anti-virus Dr.WebCureIt or KasperskyVirusRemovalTool, it is advisable to download it from a “healthy” computer, even if the system is successfully unlocked by selecting a code).
Open task manager (if possible). View suspicious processes. Try to end the process. Of course, the process will restart in most cases, but now you know what program is blocking, so you can remove it without problems.

If a virus blocks access to certain Internet resources (usually popular social networks and sites with anti-virus software), you need to remove extra entries (except for the line "127.0.0.1 localhost") from the C:\WINDOWS\System32\drivers\etc\hosts file and clear the DNS cache (with the ipconfig /flushdns command on behalf of the administrator), and also clear cookies and cache in the browser.

If the virus completely blocks the windows screen, then you can try to boot using the LiveCD and fix the problem.

If the Trojan blocks the normal safe mode, then when you press the F8 key, you must select safe mode with support for command line. On the this moment time, most winlockers are not able to block it. After downloading, you need to launch the registry editor using the regedit command and look for suspicious entries there. First of all, you need to check the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon branch, in particular, explorer.exe should be written in the Shell parameter, and C:\WINDOWS\System32\userinit.exe in the Userinit parameter, (required with comma). If everything is in order there, you need to check the same path, but in the HKEY_LOCAL_USER branch. It's also a good idea to check the branches that have startup programs, such as HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. If suspicious entries are found, they must be replaced with standard values (in the case of autoload, delete). After rebooting and logging in, the trojan can be removed manually along an already known path. This method, although effective, is only suitable for experienced users.

In addition, some Trojans replace one of the userinit.exe, winlogon.exe, and explorer.exe files in their respective directories. It is recommended to restore them from the distribution or the C:\WINDOWS\System32\DLLCACHE directory.

Windows screen lock can happen from a Trojan that creates the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\userinit.exe section, where it prescribes a call to its executable file (most often debug.exe), and to resume the system this section must be deleted.

Sometimes, if the system is completely blocked, you can use "Hot Keys"

Ctrl+Shift+Esc Call Task Manager

Ctrl+Alt+Dell Call Task Manager

Ctrl+Esc Activate the Start button

Win + D Minimize all windows (if it works, the winlock window will not interfere)

Win+M Minimize all windows

Win+R Bring up the Run window

Alt+F4 Close the active application (program)

Personally, I came across this virus 2 times, while the virus was type 5. It was easier for me to reinstall the operating system windows system. Also, I came across a windows screen lock caused by downloading an update from a dubious site.
