Well... avast! Free 2014.9.0.2018 just updated my 7-zip 9.20 to 9.22 BETA, which I find pretty annoying, because it did so without asking me (I now have changed the settings to not automatically update in the background).
In CCleaner's list of installed software I found entries for 7-zip 9.20 and 9.22. I uninstalled both versions of 7-zip and did a reinstall of the latest stable version, which is 9.20 of course. I do not want any BETA versions of software on my PC (Windows 8, 64 bit)! There must be some reason for calling 9.22 BETA. Uninstalling 9.22 caused a short crackling sound in my speakers and also a flickering on my monitor, so who knows what that BETA came with.
With all due respect to Mr. Salomon from the avast! Team, I find his explanation in the bug report (
https://feedback.avast.com/responses/software-updater-bug-for-7-zip) not satisfactory. Software being in BETA status for 3 years and being offered on a lot of portals does not make it stable. I mean, what does it say, when the update leads to two installed versions and possibly causes driver problems...!?
I am sure that 99,9% of avast! users (regardless of what avast! version they use, Free, Pro, IS, Premier) do not want BETA but stable software on their computers. I consider offering BETA versions via Software Updater a step in the wrong direction.
In addition to changing the settings for Software Updater to not automatically update in the background I have now set it to ignore 7-zip. I prefer to manually update once a new STABLE version is available.
