2009, 2010 and subsequent years brought the invasion of ransomware viruses . This is the type of program that appears during Windows startup on the user's desktop as a banner. Then - a voluntary-compulsory request to send a paid message to a specific mobile number. In this case, all user applications are blocked until the requirements of the attacker are met.
If you are trying to figure out how to unlock your computer and are ready to send sms, in no case do this. No one will give you guarantees that you will free yourself from the virus. Rather, on the contrary, the attacker will continue to extract money from you.
There are such methods for removing malware, such as disinfection in safe mode, launching a bootable CD with anti-virus scanners, special resources on which unlock keys are laid out, etc. Some of them will be considered by us in more detail. All tips are for informational purposes only.
How to unlock a computer from a virus without sending sms
There are several options, and all of them make it possible to remove a malicious banner from the desktop for free.
The first one is to use the Kaspersky website. On their resource is a deblocker - a script that generates a key to unlock.
The second is to use the Doctor Web laboratory. The result will be similar to the previous one. Both resources represent serious anti-virus companies that are closely involved in the issue of how to unlock a computer infected with a virus.
If the unlock key came up and the banner disappeared, check the PC again with an anti-virus scanner with updated definitions, suddenly there is still some other malicious software.
Virus removal using Kaspersky Virus Removal Tool.
If the above methods do not give the expected effect, you can scan your computer with an anti-virus scanner from Kaspersky - Kaspersky Virus Removal Tool. In order for the process to be accelerated, and the result is predictable, it is better to perform treatment in the diagnostic mode of Windows.
You can start this mode before booting the system by holding down the f8 key. As soon as the boot menu appears, select the “safe mode” option in it and start Windows.
The utility works in two modes: manual and automatic. A manual scan is recommended. In the selection of objects to scan, also include the boot sectors of partitions and RAM.
Additional safety net
You can unlock your computer from the virus through the registry editor. Some malware registers itself as autorun through the Explorer.exe shell or through a user initialization application, Userinit.
Launch the task manager using the keyboard shortcut Ctrl + Shift + Esc. Next, select the “Remove task” item. In the field "New task" we enter "regedit".
We go to the CurrentVersion / Winlogon section, there are two keys: “Shell”, as well as “Userinit”. The first key must contain the value explorer.exe. The second default parameter is C: \ WINDOWS \ system32 \ userinit.exe, (the comma should be at the end).
Of course, this method is best used in troubleshooting mode. How to unlock a computer if the task manager does not start with the specified combination? Try the options Ctrl + Alt + Shift + Y, Ctrl + Alt + Shift + U, Ctrl + Alt + Shift + J. Some of them may be a way to start the dispatcher.
We translate the hands of a computer clock
Sometimes an annoying banner can be removed by moving the system time back or forward for a significant period. It is clear that in this case you will have to use the BIOS. After starting the PC, press and hold Delete or another preset key until the BIOS SETUP utility starts.
Then we look for the System Time and System Date parameters. In the first of them you can adjust the system time, in the second - set the date necessary to remove the virus .
