Issues with the potentially unwanted program
There are many ways to become infected with the adware that causes Mscsmart.com pop-ups.
A large portion of these virus cases come from downloading freeware or cracked programs from peer-to-peer networks. Freeware can also be downloaded from official websites, but the adware is often bundled with it as a legal program.
A lot of users often use unreliable programs from untrusted providers, such as abandonware, free apps, and even hacked programs. All of these kinds of applications are risky because it's easy for the malware to disguise itself as part of a license hacking script or as a component of a Windows optimization tool.
Mscsmart.com can additionally be concealed in the promotion somewhere on an unusual website. Such sites are usually full of bright and blinking ads, and their proprietors usually permit any type of promotion to be posted on their page. Hence, clicking such banners is a shot in the dark: only the advertisement contractor realizes what will happen when you click this ad. Avoid anything that is suspicious.
Uninstall from Windows
Uninstall from Windows 10/8:
- Type Control Panel into the Windows search box and open the result.
- Under Programs, select Uninstall a program.
Uninstall from Windows 7/XP:
- Click on Windows Start > Control Panel (Windows XP users should click on Add/Remove Programs).
- In Control Panel, select Programs > Uninstall a program.
Remove the unwanted program:
- In the Programs and Features window, look for any recently installed suspicious entries, select them, and click Uninstall.
- If User Account Control appears, click Yes to confirm, then complete the removal.
Stream videos without limitations, no matter where you are
There are multiple parties that could find out almost anything about you by checking your online activity.
While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.
Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.
Data backups are important - recover your lost files
Ransomware is one of the biggest threats to personal data.
Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.
While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as can also be effective and restore at least some of your lost data.
Questions about Mscsmart.com ads
mscsmart.com keeps sending notifications. Is it a virus?
No. Notifications from mscsmart.com come from a permission stored in the browser, not from a program installed in Windows. Someone clicked Allow on a prompt from that site, usually without realising what it meant, and the site now sends ads through the browser's notification system.
Antivirus scans often find nothing because there is nothing to find on the disk. Removing mscsmart.com from the browser's list of allowed sites stops the messages for good. A scan is still useful if you clicked a notification and downloaded or ran something from the page it opened, because those downloads can be unwanted programs.
Did a notification from mscsmart.com infect my computer?
A notification cannot infect a PC. It is a short text with a link that the browser displays. Clicking it opens a page, and a page cannot install anything unless you agree to a download and run the file.
So the answer depends on what you did after clicking. Looked and closed: you are fine. Downloaded but did not open: delete the file.
Opened a downloaded file: uninstall what it added and scan the PC. Typed card or login details: contact the bank and change the password. In every case, remove mscsmart.com from the browser's allowed notifications so the messages stop.
Why does Mscsmart.com show me ads?
Because that is its whole purpose. Mscsmart.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 mscsmart.com safe to visit?
No. The site mscsmart.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 mscsmart.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 mscsmart.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 Mscsmart.com?
Look for notifications from mscsmart.com. That is the trace Mscsmart.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.
Why didn't my antivirus catch Mscsmart.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.
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.
Will Fortect remove Mscsmart.com?
No program removes Mscsmart.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.
