Critical Framework Error scam (fake) - Free Guide

What is Critical Framework Error scam?

Critical Framework Error is a scam that spams the screen with pop-ups and plays alarming sounds

Critical Framework Error is a scam message that plays sounds and tries to scare users into calling fake support number

Critical Framework Error might show up on the screen when users browse the web on Google Chrome or another browser abruptly. Many people are caught off guard when their screens are flooded with numerous pop-ups displaying all sorts of misleading information. To add to the confusion, an alarming, loud sound is also played, and the fake message is also narrated. The first thing to do here is not to panic, as many people do, as they are not sure how to stop it.

The top message informs users that their computer has encountered a Critical Framework Error due to an unauthorized app, which allegedly was stopped by Windows SmartScreen. It is then claimed that users need to call a provided technical support phone number to resolve the situation. In the background, many other pop-ups can be seen, as well as Windows logos and page formatting that is used by the official Microsoft website.

If you have encountered this message, please do not call the fake number. If you do, the crooks would try to scam you even further and make you purchase fake software, install malware remotely or ask you to pay for fake services hundreds of dollars. Instead, read through the information we provide below in order to remove the Critical Framework Error from your browser and ensure that your system is secure.

There are thousands of scams employed by malicious actors to carry out their deeds. From you being asked to enable notifications to allegedly verify you are not a robot to full-fletched phishing schemes that make users lose thousands of dollars. The technical support scam category, which Critical Framework Error belongs to, is one of the most damaging in terms of how much money users are scammed of their pockets every year – we are talking billions of dollars.^[1]

The first step of the scam is to make users land on the website that would display fake error messages – the URL of these sites can vary greatly, but some of the spotted addresses spreading it were yicbf3.gq or buddiesmeetup.com. Here is your first red flag: the message shows various Microsoft logos and pretends to be from the company, although the real Microsoft would never use such phony URLs.

As soon as people land one of the malicious pages, they are met with a rather large number of pop-ups. The top one, which is shown in orange/yellow color and looks like a warning, says the following:

Critical Framework error. Call immediately: +1-(888) 348-1198

Windows SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk. For technical support call on

Publisher: Unknown Publisher
App: Explorer (1).exe

[Run anyway] [Don’t run]

Windows SmartScreen is a built-in feature by Microsoft that warns users about online scams, phishing^[2] attempts, and similar. Crooks only use the name to mislead people and make them believe that the warning actually comes from Microsoft, which it doesn't.

Microsoft would never provide tech support contact details in the error message

Additional pop-ups include various other warnings such as This computer has been blocked, Windows Firewall Security Alert or Windows Support Alert. As evident, the other messages are only there to intimidate and frighten visitors even more, and everything that is claimed there is fake.

Likewise, a loud sound that of the alarm might be playing in the background, with automated text being read. This social engineering^[3] trick is commonly used by many scams – it is designed to make people panic and do what they are told. In reality, any website can play sounds automatically as soon as you enter; in this case, it is the fake warning that is being read.

In order to remove Critical Framework Error from your browser, simply close down the tab it is shown in. In some cases, it might be difficult to do due to the way the page was designed; if that happens, press Ctrl+ Shift + Esc on your keyboard and shut down the process of your browser immediately.

Check your device for adware and malware

There are two ways you might have ended on a phishing website – you either clicked a link on some malicious website (for example, torrent and similar illegal sites commonly employ fake “Download” and similar links), or your browser acted of its own volition due to adware infection. While the latter is not usually the primary cause, we strongly recommend you do not dismiss this possibility. This is especially important if you downloaded something from the phishing page or allowed remote access to cybercriminals.

Before you proceed with the steps below, you should first perform a full system scan with SpyHunter 5Combo Cleaner, Malwarebytes, or another reputable anti-malware. This would ensure that there are no malicious processes or programs running in the background. The below steps would also provide instructions to remove potentially unwanted applications that are not always detected by anti-malware tools. In other words – use anti-virus to check for high threats, and use the instructions below to get rid of browser hijackers, adware, and other unwanted software that might cause your browser to show unwanted ads.

Google Chrome

• Open Google Chrome, click on the Menu (three vertical dots at the top-right corner) and select More tools > Extensions.
• In the newly opened window, you will see all the installed extensions. Uninstall all the suspicious plugins that might be related to the unwanted program by clicking Remove.

Mozilla Firefox

• In here, select the unwanted plugin and click Remove.

Do not call the fake Microsoft technicians

Many scams impersonate well-known company names. Since the targeted audience for tech support scams is usually Windows or Mac owners, crooks commonly create fake websites designed to look like those of Microsoft or Apple, which kind of makes sense, as users are led to believe the warning comes from a legitimate source.

In reality, these and many other tech companies that provide some type of digital service would never send you alerts about your personal issues. Error codes might be shown on your system but not within your browser. Likewise, error codes never provide a contact number to resolve them – this is done precisely for the reason so that users could easier separate scams from legitimate messages. Don't forget that looks are just that – they can be fabricated easily.

If you panic and call the fake tech support helpline, you would likely be asked to provide the access to your computer remotely. At this point, cybercriminals might show you some fake “evidence” that there is a virus on your system and, in order to remove it, you need to pay a fee, which is usually quite large.

Alternatively, you might be asked to install other software that might be malicious or simply pay for the provided “services. You might also later realize that you have called a premium number and be charged a lot for it. No matter how you look at it, never call these numbers and always refer to the official website if you are in doubt.

If you have been scammed already and paid money, you should contact your bank and explain what happened – it might be possible to reverse the transaction. Also, if you have allowed remote access to your PC, make sure you scan it with SpyHunter 5Combo Cleaner, Malwarebytes, or another security software and ensure its integrity with the FortectIntego repair tool.
