Why is Avast acting like hucksters and bothering the people that bought it?

I have an issue with avast on all my systems it’s installed on. I can’t play a local video or movie disk or DVD without near constant audio hitches and 15-20 seconds of pauses every 15 min waiting for Avast to let me use the system I paid for.
Why after buying a 3 year lic for 3 PC am I consistently harassed with adverts on my desktop and elsewhere to buy more or other up selling tactics? Why is Avast acting like scammers do to gain attention? Why is my email full of pointless letters trying to sell me a product i already purchased every week. Adding to the bloated mess that makes email useless. Why is there complaints of Avast abusing people credit cards without their permission all over the internet in the past year? I have removed the auto renewal from my account that is the scam Avast is using to trick people. I turned off auto renewal after i bought Avast and Avast turned it back on. I will not be buying or using Avast after paying for it for over 10 years. You have abused me for the last time. Why hide the boot scan feature and not sell it as a unique feature? I will not be installing the remainder of my licence after formatting windows. All you had to do was listen and understand you are being abusive and your program is now making my machines a pain to use. There is more than 200 people using Avast because i either installed it on their systems or recommended it. You have now lost any and all respect I had for what you do. I don’t know why i spent the time to write this you never read anything else I sent you.

As has been told a huge amounts of times, you can disable the pop-ups in the paid versions.

Are they fro avast or do they only look like they are from avast ? I don't get mails from them.

Because many people do not realize they have auto-renewal enabled.
I turned off auto renewal after i bought Avast and Avast turned it back on.
avast doesn't turn it back on.

It is not hidden at all. protection > run scans > other scans

avast for sure is reading feedback and the tickets.
