1. I've been frustrated by the apparent proclivity of your expert volunteers to answer my [public] questions as PMs.
2. I can see no reason why I can't get normal replies, and when I try to respond to any of the PMs I have to spend a distressing amount of time to solve inscrutable captchas, which I persistently answer wrong.
3. Unfortunately I do find it necessary to ask more questions than I'd like, as I find Avast's user interface particularly opaque. I have a Premium trial, and this experience is discouraging me from continuing past the trial.
1. Not really sure what it is you are trying to put across here, I replied to your public question in the forums by asked a question (supported by an attached image) in that public topic.
2. As I said, I replied in your other topic and attached an image, to do so
I had to generated a PM to capture that image. That is why you got one, not to say you need to continue by using PMs. So you did get a reply in your topic. You shouldn't need to reply to PMs when you ask the question on a public support forum. This a simple mistaken need to reply by PM, as I I had to generate a PM in order to capture the attached image.
By now you should find that you no longer have to complete the captcha as they are for the first 3 posts only an anti-spam measure.
3. Unfortunately like most new things there will be a learning curve, line switching browser, an antivirus suite or worse still switching Operating System. Hopefully you will be able to do that a little easier niy you are past the captcha phase.
Note: I think this should have been in your other related topic
https://forum.avast.com/index.php?topic=226512.0, which I answered. In isolation it looks disjointed.
