There’s a workaround to disable the ads (shown for the VPS updates) until it’s fixed…

You need to uncheck the Show notification box after automatic update (avast UI > Settings > Update - scroll down to details).

Some of the PCs which had the issue are getting resolved so fast enough the issue should be resolved.

If you want to disable all pop-ups… you need to enable silent/gaming mode BUT this will stop all notifications including malware alerts etc.
