Avastclear: The stub cannot run installer/updater executable (code 0x3)

When attempt to uninstall Avast 7 by http://files.avast.com/iavs9x/avastclear.exe, it stops with error in the topic (after colon). In the error message, between “executable” and round brackets, the quoted path is denoted: “C:\Program Files\AVAST Software\Avast\Setup\Sfx\ (… don’t remember, but here was just one object, which name was similar to “avastsetup”, or so)”.
Searched on forum, found topic https://forum.avast.com/index.php?topic=53253.0 (by habitués’ advise). So, I create new service request in this topic. Logs are attached. What needs more? Please, help me to completely uninstall Avast!

This fix must be run from safe mode otherwise it will fail
