Is Croursem.co.in ads dangerous?
From our report of May 2025 · not reviewed since
Adware may be behind Croursem.co.in pop-ups and redirects
Although the most common reason for having unwanted ads from websites like Croursem.co.in is due to giving push notification permissions, there may be something else involved - adware.
Adware is a program that can install itself silently onto your system and flood your browser with ads, pop-ups, and redirects to infected sites. And to make matters worse, even the users who try to get rid of the problem with standard antivirus software may never feel the difference if adware is the problem.
Redirects and exposure to scam material are available simply by visiting dangerous areas of the web - consider pirated software archives, cracked program sites, pirated streaming sites, or adult sites. These locations are hotbeds for shady scripts and bundled installs that will install unwanted software like adware on your computer without your full knowledge.
Once installed on the system, adware can hijack your web browsing. You might notice an abundance of pop-up advertisements, random redirects, or promotional offers from obscure domains such as Croursem.co.in. Since the majority of such applications operate silently in the background, the users rarely become aware they've been infected until the symptoms appear.
To effectively deal with the issue, a full system scan using reputable anti-malware tools like or is recommended. Make sure your security software is updated to the latest version beforehand because it ensures it picks up the newest threats. Once the malware is removed, using a specialist cleaning tool like will help you erase browser trackers, cookies, and any residual impact of the infection.

How scammers obtain what they want
The sudden detour to a scam site like Croursem.co.in is not an accident - it's a tactical move intended to surprise users and deceive them into ill-advised decisions.
Scammers take advantage of this surprise factor, offering a well-written message that appears to be part of a routine process.
They tend to be shown with familiar-seeming requests, such as asking to verify that they're not a bot or verify that they're above a certain age. These are ways that users are used to seeing on honest sites in the past, and thus are more inclined to comply without hesitation.
In other cases, the site can grant access to a video or an opportunity to win a prize in exchange for a click on the "Allow" button. All of this is part of the scam, designed to provoke curiosity, a sense of urgency, or excitement.
Unfortunately, once "Allow" has been clicked, the website has been authorized in full to send push notifications straight to the user's desktop. Many don't even know what has occurred until they are bombarded with spammy adverts or deceptive messages long after.
It's also common for these pop-ups to include links that redirect to even more deceptive sites, threatening chains of redirects, and incessant demands for further access. Happily, users can reclaim control and ensure that these notifications are not shown at all, given the proper actions and tools.

Croursem.co.in may flood the computer with dangerous ads
Croursem.co.in is one of several scam sites designed to make money displaying deceptive, sometimes dangerous, advertisements.
The ads may begin popping up directly on your desktop, regardless of the site you're visiting, or even when your browser looks idle, but the culprit in these cases usually is push notifications - a browser feature intended to be harmless.
Scammers trick people into allowing these push notifications using deceptive means. This is done through fraudulent prompts that are encountered on risky or hijacked websites. Once you press the "Allow" button, Croursem.co.in gets the authority to push these direct notifications into your system, which are usually full of malware links, scams, or phishing.
If you block the site's notifications using your browser settings, that might stop the deluge of alerts, but not always. If you're noticing more pop-ups, if you're being redirected more frequently than is comfortable, or if nefarious content is manifesting on otherwise secure websites, there could be more at play.
Adware on your computer is usually silently working behind the scenes to cause a surge in unwanted activity. To address the root of the problem, a full scan using authentic anti-malware software is strongly recommended.

How to stop Croursem.co.in notifications
Do this in every browser you use, and in every profile inside it: each keeps its own list of sites allowed to send notifications.
Nothing has to be uninstalled for the notifications themselves.
Which browser shows the ads?
Step 1: Remove croursem.co.in from Chrome's notification list
Open More (the three dots) > Settings > Privacy and security > Site settings > Notifications, or paste
chrome://settings/content/notificationsinto the address bar.Under Allowed to send notifications, open the menu next to
croursem.co.inand choose Remove or Block, and do the same for any other address you do not recognise.Next to Not allowed to send notifications, click Add and enter croursem.co.in, so the site cannot ask again. The menus are the same in Chrome on Windows 11 and Windows 10, and each Chrome profile keeps its own list.
Chrome on Windows 11: Settings > Privacy and security > Site settings > Notifications. Full procedure with screenshots: Stop website notifications and pop-ups
Step 1: Remove croursem.co.in from Edge's notification list
Edge stores its own permission list, separate from Chrome's, and it is often the browser behind these pop-ups on Windows 11 and Windows 10.
Go to Settings > Privacy, search, and services > Site permissions > All permissions > Notifications, or paste
edge://settings/content/notifications. Removecroursem.co.infrom Allowed, then add it under Not allowed to send notifications. Notifications that show the Edge logo come from this list.
Edge on Windows 11: Site permissions > All permissions > Notifications. Full procedure with screenshots: Stop website notifications and pop-ups
Step 1: Remove croursem.co.in from Firefox's notification permissions
In Firefox the permission sits in Settings > Permissions and data > Notifications (in older versions Privacy & Security > Notifications > Settings). Select
croursem.co.inin the list, click Remove Website, and confirm with Save Changes.Firefox only shows these notifications while it is open, so if they stopped after closing Firefox, this is the browser to clean. The steps are the same on Windows 11 and Windows 10.
Firefox on Windows 11: the Notification Permissions window. Full procedure with screenshots: Stop website notifications and pop-ups
Then, whichever browser you use
Step 2: Scan the PC if you downloaded anything from the ads
Most people who only saw the notifications can skip this step. If a notification or the page it opened made you download or run a file, delete the file and run a full scan, then a Microsoft Defender Offline scan.
In Windows 11 and Windows 10 open Windows Security > Virus & threat protection > Scan options, select Microsoft Defender Antivirus (offline scan) and click Scan now. The PC restarts and the scan takes about 15 minutes, so save your work first.

Removing Croursem.co.in push notifications
After ensuring that your system is free from adware or other potentially unwanted programs, the next step is to take care of Croursem.co.in notifications.
While security software is excellent for detecting and eliminating threats, it won't stop the push notifications themselves. That's because the permission to display them was granted through your browser, not something malware scanners are designed to handle.
To put an end to these intrusive messages, you'll need to dive into your browser's settings manually.

This small but important adjustment will prevent further interruptions and help you stay in control of what appears on your screen.

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 Croursem.co.in ads
Why do I get notifications from croursem.co.in when the browser is closed?
Chrome and Edge can keep a small part running in the background so that sites can deliver notifications, and Windows shows them in its notification area. That is why messages from croursem.co.in keep arriving with no browser window open.
The permission to send them was granted when someone clicked Allow on a prompt from that site, often disguised as a robot check or a video player. Closing the browser does not remove it; only the notification settings do.
Remove croursem.co.in from the allowed sites and the background messages stop. You can also stop the browser from running in the background in its system settings, but the permission is the real fix.
I clicked a notification from croursem.co.in. What should I do?
If you only opened the page and closed it, nothing else is needed besides removing the permission from croursem.co.in. If the page asked for card details, a phone number or a password and you entered them, act on that: call the bank to block the card, or change the password from another device.
If it offered a download, delete the file unopened, or uninstall it from Installed apps if you ran it, then run a full scan. If you called a number shown on the page, follow the steps for callers in this guide. Finally, remove the permission so that no more messages arrive.
What is Croursem.co.in?
Croursem.co.in is a push-notification spam site, a kind of adware. It earns money by showing desktop notifications, and each view, click or redirect pays whoever runs it. It is not something people usually choose; it arrives through a free download, a fake button or a misleading prompt.
Croursem.co.in does not encrypt files or take control of Windows, but its ads are sold to anyone, including scam operators, so they can lead to fake virus warnings and unwanted downloads. The steps in this guide remove it from Windows and from each browser.
Why does croursem.co.in keep showing up?
There are two possible reasons. If it appears as desktop notifications, a browser on this PC was given permission to receive them from croursem.co.in, usually through a misleading prompt. That permission stays until you remove it in the browser's site settings.
If it appears as tabs or redirects, an ad on a site you visit is opening it, or an extension or program on the PC is. Test a private window: if croursem.co.in never appears there, an extension is the likely cause. The plan above covers each case.
Do I have to change settings in every browser?
Only in the browsers that allowed croursem.co.in, but checking all of them takes a minute and is worth it. We saw the notifications in Chrome, Edge and Firefox. Chrome and Edge keep their notification lists under site settings, and Firefox under Privacy & Security > Permissions.
Remove croursem.co.in and any other unfamiliar site from each list, then turn off new notification requests if you do not need them. Remember that every browser profile has its own list, so a second profile can keep the messages coming after you clean the first.
Are the pop-ups I see really from Croursem.co.in?
Compare them with the details in the table above. Croursem.co.in produces desktop notifications, and the clearest sign of it is notifications from croursem.co.in. Other adware looks similar, so check the name of the sending site at the bottom of a notification, the address in the tab that opened, or the newest entries on the extensions page.
If those match, this guide fits. If you see a different name, the same kind of steps apply, but remove the item you actually find rather than guessing.
My scan found nothing, but the ads continue. Why?
Because the source may not be a file a scanner looks for. Browser notifications are a permission stored in the browser, and many adware extensions are not flagged because they come from an official store.
Some ad-supported programs are only reported if you enable detection of potentially unwanted apps. So a clean scan does not mean the job is done. Check each browser's notification permissions and extension list by hand, and turn on Potentially unwanted app blocking in Windows Security before scanning again.
Can I turn off the pop-ups in Windows settings instead?
You can hide them, but that is not the fix. In Windows 11, Settings > System > Notifications lets you switch off notifications for a whole browser, which silences the spam together with every useful notification from that browser.
The site keeps its permission and can still send messages when you switch them back on. It is better to remove the specific site in the browser's own notification settings and block new requests. That stops the messages at the source and leaves the rest of your notifications working.
I let a "support technician" from an ad connect to my PC. What should I do?
Act quickly but calmly. Disconnect the PC from the internet first, so the connection ends. Uninstall the remote access tool they asked you to install and check Installed apps for anything else added during the call.
Run a Microsoft Defender full scan and offline scan. From another device, change your e-mail and banking passwords and sign out of all sessions.
If you paid by card, bank transfer or gift card, contact your bank or the card issuer immediately, and report the scam to the police. Do not answer if they call back.
Will Fortect remove Croursem.co.in?
No program removes Croursem.co.in 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.
