Hi newbie , I have had the same problem. Last year when I got it , I didn't notice the auto renew and was then " in " for a year.
I tried to contact Avast and got the blue page with spinning circle. Which is what I got today too !
I f I cant get through when I need to give notice, I don't want another year.
So my contract is with Digital River which, after many searches , I found is a partner of Avast.
So I contacted them even though they are based in Ireland. I sent emails and finally they rang and I sorted it out.
But I now need to make sure this is not renewed ,, so have just emailed Digital River.
