Threat attacks are what may cause the Black Virus Lockscreen to appear on a victims' computer. The Black Virus Lockscreen is commonly associated with several types of PUPs (Potentially Unwanted Programs), that carry out a bogus technical support tactic. The Black Virus Lockscreen is designed to resemble the type of warning screens that appear on computers that are running a pirated copy of the Windows operating system. When computer users use a pirated copy of Windows and attempt to download Microsoft updates, they will be locked from their computers by a lock screen stating that their copy of Windows is not valid. They are not allowed to regain access to their data until a valid serial key is entered. The Black Virus Lockscreen is designed to imitate this lock screen used by Windows to trick inexperienced computer users into paying large amounts of money or signing up for bogus technical support services.

How the Black Virus Lockscreen Attacks a Computer

There is no legitimate connection between the Black Virus Lockscreen and the Microsoft Windows, despite the fact that the Black Virus Lockscreen will claim that it is associated with Microsoft technicians. In fact, it should be obvious that the Black Virus Lockscreen is not associated with Windows due to numerous mistakes and English inconsistencies in the language displayed in the Black Virus Lockscreen. The Black Virus Lockscreen will contain the following text:

'Your Windows has been banned
This PC has been banned for terms of use violations. To protect the Windows service and its members. Microsoft does not provide details about specific PC bans.
Your PC has been banned because we detected an unusual activity on your computer. To protect the Windows service and its members. Your PC may be has been infected with viruses that do an unusual activity. To grant access back to your PC please pay some fee to trusted Microsoft Technician and the Microsoft Technician will give you a code to unlock your PC.

Recovering from the Black Virus Lockscreen

In most cases, computer users can bypass the Black Virus Lockscreen by starting up Windows in Safe Mode. Unlike many lock screen threats, the Black Virus Lockscreen also will deliver a text file containing a threatening message. This file, named 'README.txt' is dropped on the victim's Desktop and contains the message below:

'Your PC has been infected with Black virus, this virus will destroy all your files in 72 hours, to prevent this you just have to send a tweet with this template:
BlackVirus
You get me,
and my ID is: kbxt.41.5zq
so now libert me.'

This supposed 'virus' is an empty threat. Victim's computers will not be infected with any threat and, rather, are affected by a low-level threat that uses empty threats and social engineering techniques to prey on inexperienced computer users. In most cases, threats like the PUPs associated with the Black Virus Lockscreen can be dealt with easily by using a reliable security program that is fully up-to-date. For most computer users, the main difficulty of dealing with the Black Virus Lockscreen will be to bypass the lock screen preventing access to the affected computer. The most effective method requires the use of an alternate start-up method, such as using Safe Mode or an another boot source. This will prevent the PUP installed on the victim's computer from activating and displaying the Black Virus Lockscreen. Computer users can ignore all empty threats of a supposed 'virus' and simply remove the PUPs associated with the Black Virus Lockscreen and their associated files.
