Adware is unwanted software that bombards you with pop-up ads, redirects your browser, or changes settings like your homepage. It can slow down your Mac, collect browsing data, or lead to more serious threats. Common symptoms include excessive ads, unfamiliar browser extensions, or notifications from suspicious sites.
How to Remove Adware from Your Mac
Follow these steps in order for effective removal. Start with built-in tools, then move to scans if needed.
- Update macOS and Restart Go to System Settings > General > Software Update to install the latest version. macOS includes XProtect, which scans for known malware during restarts. Restart your Mac while holding Shift to boot in Safe Mode (prevents third-party apps from loading), then restart normally. This often removes basic adware automatically.
- Remove Unwanted Browser Extensions Adware often hides in browsers. Check and delete suspicious ones:
- Safari: Safari > Settings > Extensions. Remove any unfamiliar items. Also, under Websites > Notifications, deny or remove permissions for shady sites.
- Chrome: chrome://extensions/ – Toggle off or remove extensions. Reset settings via chrome://settings/reset.
- Firefox: about:addons – Remove add-ons. If issues persist, reinstall the browser from its official site.
- Check and Delete Configuration Profiles Go to System Settings > Privacy & Security > Profiles. Delete any unrecognized profiles (e.g., “AdminPrefs”) by selecting and clicking the minus (-) button. These can control adware behavior.
- Scan with a Free Adware Removal Tool Download and run Malwarebytes for Mac (free version) from malwarebytes.com. It detects and quarantines adware like pop-up generators or browser hijackers. Alternatives include CleanMyMac’s Protection module or Intego’s VirusBarrier for deeper scans. Run a full scan, quarantine threats, and restart.
- Manually Delete Suspicious Files Use Finder’s Go > Go to Folder to check these paths and delete unknown files (be cautious—back up first):
- ~/Library/Application Support/
- ~/Library/Preferences/Â (look for .plist files from adware, e.g., com.searchprotect)
- ~/Library/LaunchAgents/ and ~/Library/LaunchDaemons/ Empty Trash after deletion and restart.
If pop-ups continue, avoid clicking them—they could install more adware. For stubborn cases, consider professional help via Apple Support.
Tips to Prevent Adware on macOS
Prevention is easier than removal. Here’s how to stay safe:
| Tip | Why It Helps | How to Implement |
|---|---|---|
| Download Only from Trusted Sources | Adware bundles with free apps from shady sites. | Use the Mac App Store or official developer sites. Avoid third-party downloaders like Softonic. |
| Read Installers Carefully | Bundled “offers” sneak in adware. | Uncheck extra boxes during setup. Decline any “quick installs.” |
| Enable Gatekeeper and Notarization | Blocks unsigned or malicious apps. | In System Settings > Privacy & Security, ensure “App Store and identified developers” is selected. Apple scans apps automatically. |
| Block Pop-Ups in Safari | Stops ad triggers. | Safari > Settings > Websites > Pop-up Windows > select “Block” for all sites. |
| Use a VPN or Ad Blocker | Hides your traffic and blocks ads. | Try NordVPN’s Threat Protection or browser extensions like uBlock Origin. |
| Run Regular Scans | Catches threats early. | Schedule weekly scans with Malwarebytes or enable real-time protection in antivirus apps. |
| Avoid Suspicious Links/Emails | Phishing delivers adware. | Don’t click unsolicited links. Use tools like Apple’s Fraudulent Website Warning. |
By staying vigilant, your Mac should remain adware-free. If you’re on macOS Sonoma or later (as of October 2025), built-in protections are even stronger. For persistent issues, back up via Time Machine before deep cleans.
