Avast SafeZone 3 Browser doesn't open

Hello!
My avast browser doesn’t work at all, it doesn’t open (other browsers work). Is it possible to fix it and not to lose all the bookmarks?

What is your OS ? XP or VISTA ?
That could explain the loss of the navigator.

7 ultimate

I suppose it’s because of the recent automatic updating of Avast

Are there any ways to restore this browser to previous/default settings excluding Windows System Restore?

What browser are you talking about? Is it really SafeZone? Maybe you were upgraded to the new version and the old one was not uninstalled properly… Please can you write more details? Thanks

Yes, SafeZone was upgraded to Secure

but I uninstalled Secure browser and returned to the SafeZone Browser

Now I’m trying to restore the bookmarks ( I tried to import them in the menu of SZBrowser, but without success)

Could you, please, tell me the bookmarks’ location (W7 Ultimate)?
