“Critical System Failure” virus – what should you do about it?
If you just got an alert message on your computer screen, stating that your Windows Security has been compromised, and if the pop-up title says “Critical System Failure,” then your computer has been infected by Critical System Failure virus. This virus belongs to Tech Support Scam family, and it is meant to display deceptive and scary warnings on the PC screen. There are many similar viruses created already, such as Fake Windows Activation screen, Productkeyupdate, or “Call certified Microsoft technicians” virus. The particular threat that we are discussing in this article asks the victim to dial 855-616-6772 number to call technical support “experts,” which are simply scammers seeking to deceive inexperienced users and swindle money from them. Typically, scammers seek to achieve at least one of these goals:
- Talk the victim into buying useless and possibly insecure software;
- Gain remote access to the computer;
- Convince the victim to reveal personal data, such as bank card details.
Computer users are advised to ignore such phony alerts and take measures to remove “Critical System Failure” malware from the compromised computer. Luckily, there is a way to block these pop-ups and eliminate the virus from the system without even using a malware removal tool – just enter 642358497351 into the “Response code” box and click Next. That should close the pop-up and remove malware from the computer. If this does not work, it means that you are infected with an updated version of this malware, and it means that using a malware removal tool is the best option to get rid of it. We strongly recommend using FortectIntego or SpyHunter 5Combo Cleaner software. You can find comprehensive instructions on how to start “Critical System Failure” removal procedure below this post.
How do such viruses spread?
Tech support scammers get surprisingly creative when it comes to distribution of such malicious programs. They seek to integrate their programs into computer systems silently and without causing suspicion to actually make users believe that the computer has been compromised somehow and needs to be fixed immediately. Sadly, unskillful computer users can easily fall for such deceptive messages and call tech support scammers. What is even worse, they might believe what these scammers say and do as they command. We would like to say that all computer users should consider annoying pop-up messages or web pages suspicious if they urge the victim to get in touch with tech support team ASAP.
To avoid installing such deceptive Trojans, users should pay more attention to programs they install and how they install them. We advise users to opt for Custom/Advanced settings when installing new programs rather than leaving Default/Standard mode on. Advanced or Custom settings provide the possibility to see all attached downloads and detach them by removing check marks next to them. What is more, users should stay away from offers to install fake Java updates. These can be encountered while visiting untrustworthy third-party pages, gambling or adult-oriented sites. Such bogus software updates frequently contain hidden files that appear to be malicious. Do not be tricked into installing them unknowingly!
