Marcos,
Thanks for the reply, I have tried using IE & Firefox and there is not any issues with the notification spam. I can now assume that it was one of the extenstions apps which i downloaded that is causing the issue.
I have removed all the extensions and done a full reset on chrome, did a complete uninstall of Chrome, resintalled again and after a reboot everything seemed ok. I was able to open web pages with no issue. I installed an app called Adblock which i have had for years with no issues and the notifcation starts to spam again.
