Two Different Problems, Two Different Fixes

When pop-ups and spam appear on your computer, they're coming from one of two very different sources — and the fix depends entirely on which one is responsible:

  • Browser push notifications: You (or someone using your computer) clicked "Allow" on a website's notification prompt. These appear even when the browser is closed on some systems and look like system notifications. They're annoying but not malware.
  • Adware or PUPs: A program installed on your computer is injecting ads into your browser, redirecting searches, or generating system-level pop-ups. These require active removal.

Here's how to identify and fix both.

Browser Push Notifications

Countless websites trick users into clicking "Allow" on notification prompts by phrasing them as "Click Allow to continue" or "Verify you're not a robot." Once allowed, these sites push spam ads directly to your notification center.

How to Revoke Notification Permissions

🌐

Chrome

Settings → Privacy & Security → Site Settings → Notifications → Review and remove all under "Allowed"

🦊

Firefox

Settings → Privacy & Security → Permissions → Notifications → Settings → remove all unknown sites

🧭

Edge / Safari

Settings → Cookies and site permissions → Notifications (Edge) or Preferences → Websites → Notifications (Safari)

After removing all unknown notification sources, block future requests by default: in Chrome/Edge, set Notifications to "Don't allow sites to send notifications." This prevents new sites from asking.

Adware and PUP Removal

If pop-ups appear inside your browser on every website (injecting ads into pages that normally don't have them), or you have unwanted browser extensions you didn't install, you have adware — a type of software that monetizes your computer by showing you ads.

Step 1 — Remove Suspicious Applications

  1. Windows: Settings → Apps → sort by "Recently installed." Remove anything you don't recognize.
  2. Mac: Open Finder → Applications. Drag anything unrecognized to the Trash, then empty Trash.

Step 2 — Remove Suspicious Browser Extensions

  1. In Chrome: Menu (⋮) → Extensions → Manage Extensions. Remove anything you don't recognize.
  2. In Firefox: Menu → Add-ons → Extensions. Remove unknowns.
  3. In Safari: Preferences → Extensions. Remove unknowns.

Step 3 — Scan with Malwarebytes

Malwarebytes (free version available) is specifically designed to detect and remove adware and PUPs. Download from malwarebytes.com, run a Threat Scan, and remove everything it identifies. This one step resolves most adware situations.

Step 4 — Reset Your Browser

If ads persist after removing extensions and running Malwarebytes, reset the browser to factory defaults:

  • Chrome: Settings → Reset settings → Restore settings to their original defaults
  • Firefox: Help → More troubleshooting information → Refresh Firefox
  • Edge: Settings → Reset settings → Restore settings to their default values

Don't click fake virus warnings. If a pop-up warns that your computer is infected and provides a phone number to call or a button to click, this is a scam. Never call the number. Close the browser tab (or force-quit the browser if needed). These are social engineering attacks designed to steal money or install real malware.

Email Spam

If the spam is coming via email rather than browser pop-ups:

  • Mark messages as spam rather than deleting — this trains your email provider's filter
  • Never click "Unsubscribe" in spam emails — it confirms your address is active and often increases spam
  • Use email aliasing tools (SimpleLogin, Apple Hide My Email) for sign-ups to keep your real address private
  • If your email address has been compromised in a data breach, check haveibeenpwned.com

Persistent pop-ups? If you've tried the steps above and ads keep reappearing, bring the machine in. We do full adware removal — checking browser settings, Windows startup entries, scheduled tasks, and all installed software — and leave you with a clean, protected system.
