Malicious Browser Notifications: How to Block and Remove Them

Share this post on social...

Malicious browser notifications are unwanted alerts that can appear on your computer or smartphone after a website has been given permission to send notifications. While browser notifications are a legitimate feature used by many trusted websites, scammers can abuse them to promote misleading content, phishing pages, unwanted software, and fraudulent offers.

The good news is that unwanted browser notifications can often be stopped by reviewing your browser’s notification permissions and blocking websites you do not recognize.

What Are Malicious Browser Notifications?

Malicious browser notifications are unwanted push notifications generated by websites that have notification permission in your browser.

A suspicious website may ask you to click Allow before you can continue. The page might claim that you need to enable notifications to:

Confirm that you are not a robot
Watch a video
Download a file
Verify your age
Continue to a webpage
Receive an important alert
Access special content

If you grant permission, the website may subsequently send notifications even when you are no longer visiting the website.

Microsoft explains that website notifications can continue appearing even after Microsoft Edge has been closed when notification permission has been granted.

Are Malicious Browser Notifications a Virus?

Not necessarily.

Seeing unwanted browser notifications does not automatically mean that your device is infected with malware. In many cases, a website has simply been granted permission to send notifications.

However, these notifications can direct users toward potentially unsafe websites, phishing scams, misleading advertisements, or unwanted downloads. This is why it is important to treat unexpected notifications cautiously.

Google has also introduced additional protections against abusive notifications, including measures designed to protect users from notification-based scams and other harmful content.

What Do Malicious Browser Notifications Look Like?

Suspicious notifications can use attention-grabbing messages such as:

“Your device may be at risk”
“Your security subscription needs attention”
“You have won a prize”
“Your package could not be delivered”
“Verify your account now”
“Claim your reward”
“Your computer needs an urgent update”
“Click to remove the threat”

Not every notification containing these types of messages is automatically fraudulent, but unexpected security, financial, or account-related alerts deserve extra caution.

A particularly important warning sign is a notification that pressures you to click immediately, provide personal information, make a payment, or download unfamiliar software.

How Do Websites Get Permission to Send Notifications?

Modern browsers generally ask for permission when a website wants to send notifications.

The problem occurs when a user unknowingly selects Allow on a deceptive website.

For example, you may visit a webpage and see a message telling you:

“Click Allow to confirm that you are not a robot.”

The request may look like part of a CAPTCHA or verification process. However, granting notification permission gives the website an additional way to contact your browser.

Chrome allows users to manage notification permissions through Settings > Privacy and security > Site Settings > Notifications.

How to Remove Malicious Browser Notifications

The first step is to identify the website responsible for the notifications and remove its notification permission.

Remove Notifications in Google Chrome

On a computer:

Open Google Chrome.
Click the three-dot menu in the upper-right corner.
Select Settings.
Select Privacy and security.
Click Site settings.
Select Notifications.
Review the websites allowed to send notifications.
Find websites you do not recognize.
Block or remove their notification permission.

Google’s official Chrome support documentation explains how to allow or block notifications for individual websites.

Remove Notifications in Microsoft Edge

To block notifications from an individual website in Edge:

Open Microsoft Edge.
Click the three-dot menu.
Select Settings.
Go to Privacy, search, and services.
Select Site permissions.
Choose All sites.
Select the suspicious website.
Find the Notifications permission.
Change the setting to Block.

Microsoft provides detailed instructions for managing website notifications in Edge.

Remove Notifications in Mozilla Firefox

Firefox users can review notification permissions through the browser’s privacy and permissions settings.

Open Firefox settings and locate Privacy & Security, then find Permissions and Notifications. From there, you can review websites that have been granted notification access and remove permissions you no longer want.

Firefox also provides an option to prevent websites from repeatedly asking for notification permission.

Tap the three-dot menu.
Select Settings.
Tap Site settings.

What If Notifications Continue After You Block the Website?

If notifications continue after removing a website’s permission, consider checking the following areas.

Check Your Browser Extensions

Review the extensions installed in your browser.

Remove extensions that you:

Do not recognize
No longer use
Did not intentionally install
Recently installed before the unwanted behavior started

Only install browser extensions from sources you trust.

Check Recently Installed Applications

Review applications installed on your computer or phone.

If you find an unfamiliar application, research it before removing it. Avoid deleting important system files or programs simply because you do not recognize their names.

Run a Security Scan

If you are experiencing additional symptoms such as unexpected redirects, repeated browser changes, unusual advertisements, or unfamiliar software, consider running a security scan using reputable security software.

A notification problem by itself does not prove that malware is present, but additional unusual behavior is worth investigating.

How to Recognize a Suspicious Notification

A notification deserves additional caution when it:

Creates unnecessary urgency
Requests passwords or financial information
Claims your device has a serious problem without evidence
Encourages you to download unfamiliar software
Promises an unexpected prize or reward
Redirects you to an unfamiliar website
Requests cryptocurrency or unusual payment methods
Uses a website address that does not match the organization it claims to represent

The Federal Trade Commission recommends avoiding unexpected links and contacting companies through websites or contact information you know to be legitimate rather than relying on information provided in suspicious messages.

Don’t Trust Fake Security Warnings

One common tactic is to make a browser notification look like a message from a security company, operating system, browser, or other trusted organization.

For example, a notification might claim that your computer has been infected and instruct you to click a button.

Do not assume that a browser notification is legitimate simply because it contains a familiar company name or security-related language.

Instead, close the notification and open your security software or the company’s official website directly.

What Should You Do If You Clicked a Suspicious Notification?

If you accidentally clicked a suspicious notification, don’t panic.

If you did not download anything or provide personal information, you can generally start by:

Closing the suspicious webpage.
Removing the website’s notification permission.
Checking your browser extensions.
Reviewing recently installed applications.
Running a security scan if you are concerned.
Avoiding further interaction with the suspicious website.

If you entered a password on a suspicious website, change that password through the legitimate service and consider enabling two-factor authentication.

If you provided financial information, contact your bank or financial institution using an official contact method.

How to Prevent Malicious Browser Notifications

Prevention is one of the easiest ways to reduce unwanted browser notifications.

Be Careful With the “Allow” Button

Do not automatically click Allow when a website requests notification permission.

Consider whether you actually need notifications from that website.

Avoid Suspicious Websites

Be cautious with websites offering unexpected:

Prizes
Giveaways
Free downloads
Investment opportunities
Software updates
Account warnings
Cryptocurrency promotions

Keep Your Browser Updated

Use an up-to-date browser and operating system. Updates can include security improvements and protections against emerging online threats.

Review Notification Permissions Regularly

Every few months, review your browser’s notification permissions and remove websites you no longer use or recognize.

Chrome, for example, provides a dedicated notification settings area where users can review website permissions.

Frequently Asked Questions

Can malicious browser notifications damage my computer?

A browser notification itself does not necessarily damage your computer. However, it can lead you to potentially harmful websites, phishing pages, deceptive downloads, or other online scams.

Why am I receiving notifications from a website I don’t remember?

You may have previously visited the website and accidentally selected Allow when it requested permission to send notifications.

How do I stop fake virus notifications?

Find the website responsible for the notifications in your browser’s notification settings and block or remove its permission. You should also investigate further if you notice other suspicious browser behavior.

Can I block all browser notifications?

Yes. Most modern browsers provide settings that allow users to block website notifications or control which websites can send them.

For example, Microsoft Edge supports settings that can allow, block, or prompt users about website notifications.

Are browser notifications the same as pop-ups?

No. Website notifications and traditional browser pop-ups are different features. Microsoft specifically distinguishes website notifications from pop-up advertisements and alerts that open browser windows or tabs.

Should I click a notification saying my computer has a virus?

Avoid clicking unexpected security warnings. Instead, independently open your security software or the official website of the organization involved and check whether there is actually an issue.

Final Thoughts

Malicious browser notifications can be annoying and potentially risky, but they are often manageable without reinstalling your browser or operating system.

Start by reviewing your browser’s notification permissions and removing access for websites you do not recognize. Then check your extensions and installed applications if unwanted behavior continues.

Most importantly, don’t let an alarming notification pressure you into clicking a link, downloading software, providing personal information, or making a payment.

When in doubt, close the notification and visit the relevant company’s official website directly.
