What is Critical ERROR scam?
Critical ERROR virus is a tech support scam campaign that aims to trick people into revealing their personal details
Red screen critical ERROR virus misleadingly claims that it was triggered by Microsoft. However, it belongs to cybercriminals.
Critical ERROR is a scam that has nothing to do with Microsoft. This red screen message has been used to scare people about invented problems on Google Chrome, Microsoft Edge, Mozilla Firefox, and other web browsers. While trying to mislead users into thinking that their personal information is in danger, scammers display a red screen error that shows up on the screen while they browsing the Internet. Please, do NOT fall for Google Chrome critical error and similar scams because they belong to scammers who will do their best to steal your money, credit card details, and other personal information or infect your PC with malware.

Users might become victims of the tech support scam[1] while they are browsing on infected or high-risk websites. However, if the browser continuously opens a new tab or window with this site, it’s definitely caused by the potentially unwanted program (PUP), usually adware.
The Critical ERROR red screen virus is designed to redirect users to a corrupted website that delivers a message warning about computer infection and urges them to call a provided phone number. Criminals might pretend to be official Microsoft support technicians and:
- sell you useless security software to get your credit card information;
- convince you into installing remote access software to solve the problem quicker;
- download malware, ransomware,[2] or spyware into your computer.
Scammers are great in human psychology and can use social engineering perfectly. Thus, you may not notice how you follow their demands and give everything they ask for. For this reason, you should not call them even for fun. If redirects continue, you should take all necessary measures to remove the virus from the device.
In order to clean the computer quickly and without putting too much effort, you should take advantage of professional anti-malware software. Anti-malware such as SpyHunter 5Combo Cleaner, Malwarebytes is a perfect choice for Critical ERROR removal.
"Critical ERROR" scam might target Google Chrome, Mozilla Firefox, Internet Explorer, and Microsoft Edge users.
Versions of Critical ERROR scam
Mozilla Firefox Critical ERROR. This version of the tech support scam is designed to trick Firefox users that their personal data is in danger. The malicious website delivers a fake authentication box that requires entering a username and password. However, none of your current credentials will work. It’s trickery that is supposed to convince you into calling a fake support line.
Crooks are known for using +1 (877) 556-6888 and +1 (877) 777-8951 numbers. The message itself might also provide an error code. Currently, it delivers system errors 0xKB1546764 and 0xKB6301092. However, none of them are real, and calling provided number is not recommended.
Internet Explorer Critical Error. IE users might be tricked that their computers are infected with RDN/Trojan.worm![rand]. In order to protect their passwords, browsing-related information, browsing history, identity, and credit card information from being exposed or sold, users have to call +1 888 780 0587.
However, this number does not belong to Microsoft Technical Support, as the message says. Therefore, the call might be expensive (even if it says it’s toll-free), crooks might actually swindle your sensitive data, money, or get access to your computer.
Microsoft Edge virus affects the specific web browser. However, there are numerous versions designed to affect other web browsers.
Microsoft Edge Critical ERROR. Cybercriminals pretend to be official Microsoft technicians that report about detected viruses on the computer. This alleged system error also asks to call a toll-free number 1-844-734-4622 in order to get needed help to fix the computer.
However, Microsoft does not deliver security alerts on Microsoft Edge. Thus, this pop-up is created by cybercriminals that have hidden purposes, such as selling you useless security software or getting remote access to your PC, and installing malware.
Google Chrome Critical Error. Chrome is the most popular web browser, so there's no surprise that Chrome users can receive a Critical Error alert too. This version of the tech support scam barely differs from the previous ones. Scammers threaten that user's private information might be in danger, and they need to call + 1 (888) 562-5234 phone number to get needed help.
However, redirects to a malicious website that delivers a fake critical error pop-up are usually triggered by adware. Thus, users are advised to check the computer’s security and eliminate the potentially unwanted program to stop this activity. Hence, calling a fake “Help Desk” won't help to solve the problem.
Google Chrome error virus is the most popular version of the scam.
Users fall into installing adware because of a lack of attention
As you already know, various adware programs might be responsible for redirecting to the Critical system ERROR scam websites. Infiltration of the PUP might seem mysterious. However, security experts from the UK, Germany,[3] and the U.S. report that there’s no mystery; it’s only a deceptive software marketing method known as bundling.
It allows adding the PUP into the freeware or shareware package. Therefore, when a user downloads a program, he or she might install it as well. The hijack might be unexpected if you use a Standard/Recommended setup because it does not openly disclose about third-party apps. Thus, you should never rely on them.
Always install new software under Advanced/Custom settings and opt-out of all pre-selected applications. Most of them are useless, and you should not test out them.
Get rid of Critical ERROR virus from your browsers entirely by using a simple guide
To remove the virus from Internet Explorer, Microsoft Edge, Mozilla Firefox, or Google Chrome might seem like a simple task. However, you will have to find all PUPs, hijackers, and adware hiding on your system and causing fake ads while you are browsing the web. Typically, such threats infiltrate systems together with legitimate software, so there is no surprise that you can't remember downloading such a virus to your computer.
If you want to fasten the entire process, we recommend using anti-malware software. Updated security software can not only take care of Critical ERROR removal. It can also help you identify and terminate all PUPs that are considered to be suspicious. After you finish this procedure, make sure you reset your web browsers to clean them entirely.

How to prevent from getting malware
Access your website securely from any location
When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.
If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.
Recover files after data-affecting malware attacks
While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.
Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
