Norton appearing on my MacAir

I have a MacBook Air, bought in May 2026, macOS Tahoe 26.5.2. I clicked on a web page in Google Search today and a new page opened called SafeWeb. The message said 'Dangerous web page blocked. This is a known dangerous webpage. It is highly recommended that you do NOT visit this page.' It also said on the page that it is blocked by Norton.

In the address bar it says Norton Safe Web then 'chrome-extension://fnpbeacklnhmkkilekogeiekaglbmmka/content/ui/blockedPage.html?originalURL=https://blackjacktrailerjacks.com.au'

I have opened the blackjack trailer jacks webpage on my iPad and iPhone with no problems

I don't have Norton installed on my MacAir.

In Google Chrome I clicked the three dots in the top right corner, selected Settings, clicked on Privacy and Security, selected Site Settings, clicked on Notifications under Permissions. I looked at Allowed to send notifications and there is Norton Password Manager and Norton Safe Web.

Also when I go to fill in passwords on other sites Norton Password Manager makes suggestions for passwords - which I don't use.

I have Norton installed on my Windows laptop. I'm thinking that Password Manager and Safe Web somehow came across to my Mac when I installed Google Chrome. Is this possible???

How do I get Password Manager and Safe Web off my Mac?

Sorry this is long winded!!! I hope someone can help me.

MacBook Air 15″, macOS 26.5

What you have described shows that Norton Safe Web and Norton Password Manager are installed as extensions in Google Chrome on your Mac. The chrome-extension://... address in the warning is consistent with Chrome displaying a page supplied by an extension.


You can remove both without removing anything from macOS. 


In Chrome, click the three dots in the top-right corner, choose Extensions >> Manage Extensions, find Norton Safe Web, click Remove, and confirm. 


Do the same for Norton Password Manager. Google gives the same procedure in its current Chrome instructions. (Google Help)


I would not delete anything from your Mac's Applications folder or Keychain at this point. 


Removing the Chrome extensions is the appropriate first step.


It is possible that the extensions became available on your Mac because you are signed into Chrome and use Chrome's extension syncing, but we cannot establish from the information available that this is what happened. 


Google confirms that Chrome can make extensions available on other computers when you sign in to Chrome. (Google Help)


After removing them, quit Chrome completely and reopen it. 


Then check Extensions >> Manage Extensions to make sure they are still gone. 


If either extension comes back, that would be the time to investigate Chrome synchronization or another installation mechanism.


The Norton warning itself was generated by Norton Safe Web, rather than by macOS. 


I would therefore not change any Mac security settings simply because you were able to open the website on your iPhone or iPad.


For completeness, Apple has its own instructions for managing extensions in Safari. 


They are separate from Chrome's extensions. In Safari, you can go to Safari >> Settings >> Extensions to turn extensions off or uninstall them. 


Apple: Use Safari extensions on your Mac


Apple: Get extensions to customise Safari on Mac


Google: Install and manage Chrome extensions


In your particular case, I would simply remove Norton Safe Web and Norton Password Manager from Chrome first. 


You do not need to uninstall Norton from your Windows laptop, and you do not need to change anything on the Mac beyond the Chrome extensions.
