Question details

The user is encountering continuous fake malware alerts or unwanted push notifications from their web browser, despite standard security software showing no active threats.

How to Stop Persistent Malware or Browser Notification Messages

Product: Web Browsers
Device & OS: Windows
Scenario: Using a computer or browsing the internet when intrusive security warnings and fake alerts repeatedly pop up on the screen.
Observed behavior: The browser or system continuously displays fake virus alerts, unsolicited advertisements, or deceptive security messages triggered by adware or malicious site permissions.

Before you start

Before modifying your system or browser settings, save any open work and close unnecessary tabs. It is also recommended to disconnect from the internet temporarily to prevent further unwanted pop-ups during the cleanup process.

Solution 1Recommended

Revoke Browser Notification Permissions

Block malicious websites from sending fake security alerts by checking and removing unrecognized site permissions in your browser.

Many persistent alerts are not actual viruses, but rather push notifications from websites that tricked users into clicking 'Allow'. Revoking these permissions immediately stops the spam without requiring additional software.

Access Site Settings

Open your browser's settings menu (usually found by clicking the three dots in the upper right corner) and navigate to 'Privacy and security'.

Open Notification Permissions

Click on 'Site Settings' or 'Permissions', then scroll down and select 'Notifications'.

Remove Untrusted Sites

Review the list of websites allowed to send notifications. Click the three dots next to any unfamiliar or suspicious website and select 'Remove' or 'Block'.

Tip: To prevent this issue in the future, you can toggle the setting to block websites from asking to send notifications entirely.

Solution 2

Remove Suspicious Extensions and Reset Browser

Clear out hidden adware and reset corrupted configurations by removing unknown extensions and returning the browser to its original state.

Solution 3

Run a Microsoft Defender Offline Scan

Use a deep-level offline malware scanner to find and eliminate persistent threats that standard scans might miss while the operating system is running.

Frequently Asked Questions

Why am I getting antivirus pop-ups when I do not have that specific software installed?

These are typically deceptive push notifications from malicious websites you accidentally granted permissions to, rather than actual system warnings. Scammers design these alerts to mimic real antivirus software like McAfee or Norton to trick you into clicking malicious links.

Will resetting my web browser delete all my saved bookmarks and passwords?

No. Using the built-in 'Reset settings' feature in major browsers like Chrome, Edge, or Firefox will clear cookies, unpin tabs, and disable extensions, but it is designed to keep your bookmarks, browsing history, and saved passwords completely intact.

How do browser hijackers and adware get installed on my computer?

They are frequently bundled with free third-party software downloads, deceptive pop-up advertisements, or fake software update alerts. You can avoid them by downloading applications directly from official sources and unchecking bundled offers during installation.
