Fed up

I’m close to fed up with Avast. Every time I renew or upgrade, some dire warning appears telling me that my computer is still not secure because I haven’t purchased another guard. It just goes on and on and on. Does this product secure my information and protect my hardware or not? I feel like there is a bait and switch going on.

You don’t say what Avast Program you are using, presumably Avast Free ?

I have been using Avast Antivirus Free for a little over 20 years - most free products try to get you to purchase the paid product/s

You don’t say where you are seeing these ?
I suspect in the Smart scan, but it could be other locations.
