I had two ad blockers in chrome which I have now disabled and removed. However, they have left behind some of their instructions.

I cannot click on any google ad links which I now need to do as I am running ads.

I cannot use google analytics with https://analytics.google.com/analytics/academy/

But I can go here

https://tagmanager.google.com/#/home

but if I select an analytics account like https://analytics.google.com/analytics/web/#embed/report-home/a116505845w172941436p172396281/ I get

This site can’t be reached. Check if there is a typo in analytics.google.com
If spelling is correct, try running windows network Diagnostics.
DNS_PROBE_FINISHED_NXDOMAIN

Do I need to do a registry clean? The adblockers have clearly messed something up.

I tried CCLEANER but no joy
