Well that was a right palaver...
Went for a repair and it froze when reinstalling the firewall
So I had to reboot then when I tried to do a clean install Avast setup was running all the time and I could do nothing. Not even Avast clear would run
So I had to disable self protection, shut all services down and then use Revo to remove it
Then I could run Avastclear
Went for a full re-install and now not only does safezone work but I have secure DNS back
However, my account is down and I cannot log in with Avast
