"StalinLocker" virus removal guide
What is "StalinLocker"?
Discovered by MalwareHunterTeam, StalinLocker is newly-discovered malware that stealthily infiltrates the system and locks the computer screen. StalinLocker then displays a full-screen window whilst simultaneously playing the USSR national anthem. In addition, this malware terminates most processes (including "Explorer.exe" and "taskmgr.exe").
The lock-screen window contains Joseph Stalin's portrait and a short message in Russian stating that users must enter an 'unlock code' within 10 minutes (there is a countdown timer) to restore the system. If the code is not entered, the malware will delete all files stored on the computer. Note that this malware provides no information regarding the code - it is unclear as to the format of the code and how to retrieve it. Fortunately, MalwareHunterTeam analyzed StalinLocker's source code and determined the code's formula: subtract the StalinLocker execution (infection) date by 12/30/1922 (the date when the USSR was founded). Once the code is entered, the malware will immediately terminate and remove itself. Fortunately, most reputable anti-virus suites are capable of detecting StalinLocker and preventing infiltration. Therefore, you are advised to have antivirus software installed and running.

StalinLocker has very similar characteristics to Product Key Has Expired, Your Computer is locked !, and many others. All are designed by different cyber criminals, but have identical behavior - they lock the computer screen and demand a code. Unlike StalinLocker, however, these viruses attempt to trick users into paying for the keys or for help in resolving the issue. In case of such infections, never attempt to contact "tech support" (or other people) via email addresses or telephone numbers provided, and certainly do not pay for anything. This is a scam.
How did potentially unwanted programs install on my computer?
How to avoid installation of potentially unwanted applications?
The main reasons for computer infections are poor knowledge and careless behavior. Therefore, pay attention when browsing the Internet and downloading/installing software. Think twice before opening email attachments. If the file(s) seems irrelevant or has been received from a suspicious/unrecognizable email address, delete the email immediately and certainly do not open any attachment. We also strongly recommend that you carefully analyze each step of the download/installation processes and opt-out of all additionally-included programs. Software should be downloaded from official sources only, using direct download links. Third party downloaders/installers are monetized by promoting PUPs, and thus, these tools should not be used. The same applies to updating software. Apps should be kept up-to-date using implemented functions or tools provided by the official developer only. Having a legitimate anti-virus/anti-spyware suite installed and running is also paramount. The key to computer safety is caution.
