I know this is a relatively old thread, but it is one of the longest on this topic, which pops up all over this forum, if you search for “this site is safe” (complete with the quotation marks).

I have registered for this forum with the specific hope that I might encourage as many Avast users as possible to complain about the “this site is safe” popup. The quoted link above is the Avast contact page. Please write to them and tell them what you think about this intrusive popup.

What makes it so annoying is that it is so unnecessary. The small checkmarks do a fine job of informing us, then you make the mistake of allowing your mouse to hover on a search result and up this great popup flies, and in many cases, simply refuses to go away. I’ve heard it is supposed to last for only three seconds, but I have had many instances where it remains until I leave the web page itself.

I have written to Avast asking for the option specifically to disable the popup. That way, those who see some benefit (really?) are welcome to keep it, while the many who have written to this forum complaining, like me, would be able to get rid of it.

I know you can totally disable the AOS extension, but that throws out the baby with the bathwater, as the extension does a number of useful things beside the annoying popup.
