What is Critical System Failure?
Critical System Failure pop-up is a scam that imitates a Windows alert that attempts to persuade you to believe that your system has irreversible problems. The message doesn’t say though what kind of error did occur and as the only method of problem solving offers a phone number of technical support. The message appears on top of all applications and windows, and can’t be close without entering a response code. Since a victim of the scam doesn’t have even a slightest idea what this code is like, they, maybe after some reboots, dial the number.
After that a victim is connected to a member of a fake support, who starts offering questionable services and software. The purchasing of those is not advisable, as the alert itself is scareware and in reality it doesn’t require much to remove Critical System Failure. If your system is infected with this malware, then enter ‘642358497351’ to the Response Code area and click Next. If that has no effect, then you can use the instructions above.
