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.
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.
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.
