A message with this number came up on my computer to call windows support, this was a scam

I had just clicked on the "50 times the Queen was not amused" article on Elle.com at about 8pm AEST on 27/4/2022, when my laptop screen was completely covered by 4 "error messages", one on top of the other, the top two stating "Do not restart or use your computer. Your computer is disabled. Please call Windows. Access is the block security reason for this computer. Please contact us immediately. A technician will help you solve the problem" and "App:Ads.browserObject(2).dll Threat Detected Trojan Spyware" and "Access to this PC has been blocked for security reasons. Contact Windows Support: (02) 4072 0821 (Security Helpline)".
The window underneath stated " Your computer has alerted us that it has been infected with a Trojan Spyware. The following data has been compromised.
> Email Credentials
Call Windows Support: (02) 4072 0821 (Security Helpline)"
And the bottom window stated "Contact support (02) 4072 0821 (Security Helpline)".
Three of the windows included the Microsoft logo and there was an audible beep when the messages were displayed.
The poor/nonsensical English in parts of the error messages alerted me to a probable scam and so I did not phone the "Security Helpline" but switched off the laptop, restarted it and ran my Norton system scan. It turned up and fixed one adware problem and my laptop then ran as normal with no problems.
Given that the Microsoft Australia helpline number is 13 20 58, I believe that this was an attempt to obtain online access to my laptop for phishing or infection purposes and that the phone number (02) 4072 0821 should be investigated.
