I'm getting malware warnings popping up on my computer through Google Chrome, but my antivirus says my system is clean. How do I get rid of them?

The good news is if these warnings appear as banner notifications from Chrome, your computer probably isn't infected with malware. Instead, you're likely seeing ordinary website notifications being misused by scammers.
At some point, a website asked for permission to "Show notifications," and you clicked Allow—perhaps to read an article, bypass a fake CAPTCHA prompt ("Click Allow to prove you're not a robot"), or stream a video.
That permission allows the website to send fake security warnings to your desktop, even when Chrome is minimized and you aren't visiting that site.
How to Spot a Fake Security Warning
Scammers use familiar antivirus logos and alarming headlines like "Your PC is infected with 5 viruses!" or "McAfee subscription expired today!" to create panic. Look for these warning signs:
-
A website address: If the notification identifies an unfamiliar website as its source, that's a strong clue it didn't come from your antivirus software.
-
Pressure tactics: Countdown timers, flashing warnings, and threats of immediate data loss are designed to make you react without thinking.
-
Phone numbers or payment demands: These lead to fake tech support representatives seeking remote access or charging for bogus cleanup services.
The fact that your antivirus found nothing is another indication that these warnings are fake. Scammers are abusing Chrome's notification system to make you think you're infected.
If you provided passwords, change them from another device. If you entered payment information, contact your card issuer. If you granted remote access, disconnect from the internet and seek trusted professional assistance to ensure nothing malicious remains.
How to Turn Off Fake Notifications
Stopping these alerts requires revoking the website's permission inside Chrome. Type chrome://settings/content/notifications into Chrome's address bar and press Enter, then:
-
Under Allowed to send notifications, look for unfamiliar websites, especially those with strange names or words like "alert," "notify," or "security."
-
Click the three dots next to suspicious websites and choose Block. Choosing Remove revokes permission but may allow the site to ask again.
If the Alerts Continue If blocking suspicious websites doesn't solve the problem, try these steps:
-
Check other browsers: Microsoft Edge and Safari have their own notification permissions.
-
Check Chrome extensions: Type chrome://extensions into the address bar and remove suspicious extensions you don't need.
-
Run Safety Check: Go to Settings > Privacy and security > Safety Check and review any warnings about deceptive websites or extensions.
-
Reset Chrome: Go to Settings > Reset settings and choose Restore settings to their original defaults. This disables extensions and resets site permissions without deleting bookmarks or saved passwords.
If warnings persist after these steps, unwanted software may be installed despite the earlier clean scan. Consider a second-opinion malware scan or professional assistance.
Prevent Future Alerts
If you don't use website notifications, select Don't allow sites to send notifications on Chrome's notification settings page. This prevents websites from requesting permission in the future. You can still make exceptions for trusted websites later.
And remember: No legitimate website needs notification permission to prove you're human or let you watch a video.
