I have used avast safezone a really long time and i got many bookmarks i use on a daily basis.
But after the update i could not import them setting=import bookmarks=avast safezone (securecopy), and then import, but when i do it says ‘‘done’’. but i get nothing out of it. 
I don’t see a reply/solution to this issue… is there one? I am having the exact same issue a year later (vs when this question was asked). Thank you.
