Mcprotectionlab.com is a fake website made to deceive you into downloading software
Mcprotectionlab.com is a fraudulent site set up by cybercriminals to spread false information.
Its usual methods include showing fake virus infection alerts, rerouting users to other malicious sites, and prompting visitors to enable notifications - ultimately leading to an inundation of phishing content straight onto their desktop screens.
Mcprotectionlab.com is one of the countless websites that display bogus virus scan results in an effort to scare people into thinking that their systems are infected and that their security and personal safety are at risk. Scammers want to get people to download software so they can profit from it financially.
You should not click any links or download any software from this website since everything displayed on it is fraudulent. Even though all of the claims made on the website are false, we nevertheless advise checking the system for adware and other infections because individuals who have them are more likely to be exposed to advertising, pop-ups, redirects, and phishing content online.

How crooks operate
Users are taken off guard when they visit the Mcprotectionlab.com website, which greatly helps the scam's effectiveness.
They see a system scan that was allegedly performed by a reputable security company. In just a few moments, users are introduced to the following alarming "scan results":
A common social engineering approach used by cybercriminals is the inclusion of recognizable components (brand names, logos, etc.) on websites to persuade users to act in ways they otherwise wouldn't – such as revealing personal information or downloading malware.
The fraudsters behind Mcprotectionlab.com want to sell software by using affiliate links. While generally harmless and a beneficial commercial strategy, the practice turns harmful when it uses deceptive tactics to convince users to download software. Always keep in mind that only trustworthy security software installed on your device is capable of diagnosing your system - no website can do this.

In fact, there are numerous websites that use the exact same tactic, including Ultrapromob2.click, Milipili.click, Vital-scanner.com, and many others.

How to deal with the scam
The first thing you need to do is refrain from clicking any of the buttons or links that are displayed on it.
Here, redirects to other fraudulent websites are very common, so you risk downloading malware or giving out your personal information. If you have already given out personal details like your phone number, email address, or credit card number, be ready for the repercussions: be exceedingly cautious, as you may be the subject of other phishing attacks.
Since users who are infected with adware are more likely to receive suspicious redirects, it is advisable to check your device for adware. Also, removing push notifications if you have accepted them is also necessary, as pesky ads won't leave you alone.
1. Check the system for adware
If users encounter Mcprotectionlab.com redirection, their systems may be infected with malware or adware. Software known as adware is frequently included with shareware and downloaded unintentionally from external websites. Some people may also install adware after being tricked by a freeware package or a fake Flash Player update.
Security applications can find and quarantine everything suspicious on your system and also prevent future malware attacks. If you have downloaded software from the scam site, you should immediately uninstall it - or anti-malware would remove it for you if it is actually malicious.
You should clear the caches from your browser after removing all dangerous malware from your computer. This is essential to make sure that cookies set on your browser are no longer used to monitor you by unknown third parties. Use for an immediate fix, or use the following manual steps:
MS Edge (Chromium)
2. Remove push notifications
The moment you enter the site, you might see a prompt asking if you want to enable push notifications. If you accidentally hit "Allow" or do it on purpose, know that later you'll be spammed with pop-ups that appear at any time - even when the browser is not being actively used.
What's even worse is that Mcprotectionlab.com would show more false messages about viruses and promote links to sites that could harm your computer. So, don't click on anything from the website. To stop it from appearing, go into your browser settings and block the website's URL from the "Allowed" list:
MS Edge (Chromium)

- You should not interact with the content shown by a scam website.
- Instead, check your system for adware or malware infections with security software

Protect your privacy - employ a VPN
There are several ways how to make your online time more private - you can access an incognito tab.
However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise.
Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and VPN will let you browse the Internet without a feeling of being spied or targeted by criminals.
No backups? No problem. Use a data recovery tool

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. is one of the leading file recovery solutions you can find on the market - it is likely to restore even lost emails or data located on an external device.
Questions about Mcprotectionlab.com ads
How do I stop notifications from mcprotectionlab.com?
Remove its permission in the browser. The bottom line of each notification names the browser, so open that browser's notification settings and look under Allowed. Remove mcprotectionlab.com and any other site you do not recognise.
In Chrome and Edge this is under the site settings for notifications; in Firefox it is under Settings, Permissions and data, Notifications. Do this in every browser profile, because each one keeps its own list.
Restart the browser and wait a few minutes. If a message still arrives, read its bottom line again: the sending address can differ from the site you remember, and that is the entry still left in the list.
The mcprotectionlab.com notification said my PC is infected. Is it true?
No. Notifications from mcprotectionlab.com are adverts written to look like system messages. A website cannot scan your files, so it has no way to know whether your PC is infected; it shows the same warning to everyone who allowed its notifications. Real Windows Security messages name Windows Security in the bottom line, not a browser and a website.
If you want to be sure, open Windows Security from the Start menu and run a quick scan there. Then remove mcprotectionlab.com from the browser's notification settings so the fake warnings stop arriving. Do not call any number or buy anything the notification or its page suggests.
Why does Mcprotectionlab.com show me ads?
Because that is its whole purpose. Mcprotectionlab.com is a push-notification spam site, and its operators are paid for every ad it displays and every click it gets. In this case the ads take the form of desktop notifications.
They are chosen by ad networks that accept almost any advertiser, which is why so many look like warnings or prizes. The ads are not a sign that your PC is broken or infected with something worse; they are a sign that something on it, or in the browser, has permission to advertise. Removing that permission or program stops them.
Is mcprotectionlab.com safe to visit?
No. The site mcprotectionlab.com exists to push visitors towards ads, and the pages it leads to include fake virus warnings, fake updates, prize scams and notification prompts. Visiting it once does not infect an up-to-date PC, but anything you click or download there is a gamble.
Do not enter personal details, do not allow notifications and do not call phone numbers it shows. If it opens by itself, close the tab and check the browser's extensions and notification permissions. Blocking the single domain helps little, because the operators register new names regularly.
Which browser is sending the mcprotectionlab.com notifications?
Each notification shows the name of the browser and the site in its small print. In the cases we saw, the messages from mcprotectionlab.com came through Chrome, Edge and Firefox. Permissions are stored per browser and per profile, so removing the site in one browser does not affect another.
If you use several Chrome or Edge profiles, check each one. If you sync the browser with an account, remove the permission while signed in, otherwise another computer may still hold it and keep receiving the same messages.
How do I know the ads come from Mcprotectionlab.com?
Look for notifications from mcprotectionlab.com. That is the trace Mcprotectionlab.com leaves, and it shows up as desktop notifications. Ads that appear on every site, including ones that never carried ads before, point to something on your PC or in the browser rather than to the sites themselves.
A quick test is a private window, where extensions are off by default: if the ads disappear there, an extension is responsible. If they appear even with the browser closed, the source is a notification permission or a program in Windows.
Did clicking Allow install anything on my PC?
No. Allowing notifications stores a permission in the browser and nothing else. No file is downloaded and no program is added to Windows, which is also why antivirus scans find nothing. The risk comes later, from the notifications themselves: they lead to scam pages, fake updates and phishing forms.
Remove the permission in each browser where you allowed it. If you clicked a notification and downloaded something afterwards, delete that file and run a Microsoft Defender full scan and offline scan.
Why didn't my antivirus catch Mcprotectionlab.com?
Many security products do not block adware or notification sites by default, because users often agreed to them, even through a misleading prompt. Notification spam installs nothing at all, so there is no file to detect.
In Windows 11 you can make Microsoft Defender block potentially unwanted apps: open Windows Security > App & browser control > Reputation-based protection settings and turn on Potentially unwanted app blocking. If notifications caused the pop-ups, no scanner will report them; the fix is in the browser's site settings.
An ad showed a phone number and I called it. What now?
The number belongs to scammers, not to Microsoft or an antivirus company. If you only talked, hang up and do not call back. If you let them connect to the PC, disconnect it from the internet, uninstall the remote access program they used, such as AnyDesk, TeamViewer, ScreenConnect or UltraViewer, and run a full and offline scan.
If you paid or gave bank details, call your bank at once on the number printed on your card. Change any passwords you typed while they were connected, and report the call.
Will Fortect remove Mcprotectionlab.com?
No program removes Mcprotectionlab.com itself, because there is nothing on the PC to remove: the notifications come through a permission saved in the browser, and only the browser's settings take it away, as the steps above show.
What Fortect can do is check the rest of Windows. Its free scan looks for malware, unwanted programs and damaged system files, which is useful if you clicked the ads, downloaded something from the pages they opened, or are not sure what else changed on the PC.
If the scan finds nothing and the notifications stopped after you removed the permission, this problem is solved. Use Microsoft Defender as a second opinion whenever you have downloaded files from pages like these.
