Since Google Chrome's last update, Avast is causing issues with saving settings.

Yeah and for whatever reason you cannot delete extension. Tried to remove adblock plus and everytime I removed it and restarted chrome it automatically installed it back. Deleted Avast from PC and the problem was instantly gone. And this was like 5 minutes ago so idk what the patch should've fixed.

Perhaps the clue is in the post 2 above yours.

Hello everyone,

we had a bug preventing saving Chromium-based browser settings in certain conditions. It is fixed in VPS 240709-00 which was released a couple of minutes ago. Sorry for any inconveniences this may have caused.

EDIT: A restart might be needed for the fix to take effect.

Best regards,
Jiri

The Italics are my highlighting what was fixed.
This doesn't seem to be what you are experiencing

The problem also affected the installation of extensions, it caused them to be installed in Chromium (Chrome, EDGE, etc..) but when the browser was reopened the extensions were no longer there. 
So it may be that it didn't even uninstall them correctly and when reopened they reappeared.

Yes this is a giant screw up for Avast.  Several days without any information and then a limited release of information in some forum posts.

I've been using your business cloud product (Essential Business Security) for some of my clients.  After, this, I'm done.  I'll use something else.

Does Avast have any technical documentation regarding what it does when it saves and later restores Chrome settings including extensions?

The issue was not with Avast restoring the settings, but preventing Chrome from saving them in the first place: There was a bug in our core scanner leaving the file open after scan, which prevented Chrome writing to that file so once you closed Chrome, all (or at least most) of settings changes got lost.

I probably should have worded the restart recommendation better as I meant computer restart. As I mentioned above, the problem was with an accidentally left opened file by our scanner, so removing the scanner also fixes the problem as the file gets closed automatically by Windows with the scanner process termination.
