I have a paid 3-machine Avast Internet Security licence, running on Win 10 machines. Two of these machines received the 1903 update notification, and prior to running this, I took all usual precautions including "Disable Permanently" all Avast shields. Both updates failed at the very end with the 0x80070005 MS update error, and various actions and reruns did not solve this.
I then uninstalled Avast on both machines via Control Panel, and reran the updates which completed successfully. I then had to download and reinstall my AIS, including reinput of the paid code.
I would rather not have to do this every time there is a W10 Feature update. My question therefore is how can I disable Avast from running, whilst leaving it still fully installed?
It seems to me there are two possibilities.
1) All the main elements of Avast (excluding folders in Program Data and Appdata) seem to be contained in \Program Files\Avast Software etc. If this folder was temporarily renamed, then presumably Avast would not be able to run. Am I correct, and is this indeed an option?
2) Alternatively, could I temporarily disable the Avlaunch program in Startup, along with all the AV services entries?
I realise that the system needs to be restarted after either of these changes, to bring it up without a running Avast.
If anyone else has suggestions and/or experience as to how to deal with this problem vis-a-vis Win 10 updates and Avast, I'd welcome them.
