Your screen keeps filling up with popups. Fake McAfee warnings saying your subscription expired. “Your computer is infected, click here.” Prize wheels, sketchy ads, virus alerts that wont go away no matter how many times you close them. They even show up when your browser is closed.
First thing to know: you’re probably not infected, and you dont need to pay anyone. This is one of the most common scams going right now, and once you know the trick its usually a five minute fix. We deal with this one for Fort Myers business owners just about every week.
If you searched “pop ups all over my screen,” this is probably why
People land here after typing things like “mcafee popups all over my screen,” “how do I stop pop ups on my computer,” or “virus pop up wont go away.” Those all point to the same thing, and its almost never a real virus.
At some point you were on a website and a little box slid down from the top of the screen. Something like “This site wants to show notifications,” with an Allow button and a Block button sitting side by side. You clicked Allow. Maybe by accident, maybe because a page told you to click it to “prove youre human” or to keep watching a video.
What actually happened to your computer
That box is your browser’s notification system. Every browser has one, Chrome, Edge, Firefox, Safari. Legit sites use it fine, your bank or calendar might send a real alert. Scam sites abuse it. The second you hit Allow, that site can fire popups at your device whenever it wants, closed browser and all.
The fake McAfee ones are everywhere lately. They copy McAfee’s logo and colors and tell you your subscription expired or a virus was found, then push you to “renew” on a fake page or call a phone number. Its all fake. McAfee doesnt work through random popups like that, and a real virus warning never comes with a phone number to call.
Here’s the part that catches everyone. Nothing is installed on your machine and your browser isnt broken. You just gave a bad website a key, and now its walking in the front door. So you dont remove a virus. You take the key back.
How to stop the pop ups: remove the notification permission
Whatever browser you use, the idea is the same. Go into the notification settings, find the junk site that has permission, and kick it out. Popups stop.
Chrome
Paste this into the address bar and hit Enter:
chrome://settings/content/notifications
Youll see a list of sites allowed to send notifications. Look for anything you dont recognize, usually weird looking web addresses. Click the three dots next to each one and pick Remove. Not sure if a site belongs? Remove it anyway, nothing bad happens. Worst case a site you actually like asks again later. While youre there, turn off “Sites can ask to send notifications” at the top.
Microsoft Edge
Paste this in and press Enter:
edge://settings/content/notifications
Same drill. Find the junk in the Allow list, click the three dots, choose Block or Remove.
Firefox
Menu (three lines, top right), then Settings, then Privacy & Security. Scroll to Permissions, find Notifications, click Settings next to it. Set the bad sites to Block or remove them, then save.
On your phone
Phones get hit too. Chrome on Android: three dots, Settings, Site settings, Notifications, then clear out anything you dont trust. iPhone: open the Settings app, find Safari, and check notification permissions there. Same idea, take the permission away.
Don’t do these things
Dont click anything inside the popup, not even the X. Scammers love hiding downloads and redirects behind that X button. Close the whole tab or window instead, using your browser’s own controls. Dont call any phone number in a virus warning, thats always the scam. And dont “renew” a McAfee subscription from a popup. If youre honestly worried about your antivirus, open McAfee from your Start menu or go straight to mcafee.com yourself, never through a popup link.

How to keep it from happening again
The whole thing falls apart if you never hit Allow. So when a website you dont know asks to send notifications, click Block or just close the tab. No normal site needs to send you desktop alerts. If a page claims you HAVE to allow notifications to continue, thats your cue to leave. A decent ad blocker helps too, since it stops a lot of these redirect popups before they load.
When it’s actually something worse
Most of the time, clearing notification permissions fixes it completely. But if you also downloaded and ran something you shouldnt have, there could be real adware on the computer. If youve cleared the notifications and the popups still wont quit, that’s when a proper malware scan is worth it.
