My Avast Virus program wouldn't update the virus definitions. I ended up having to uninstall the program and reinstall it. The browser was working before the uninstall but not it isn't. It won't open even if I open it as an administrator. I would just remove it and reinstall it but don't want to loose my bookmarks. Is there a way to reinstall or update the browser without loosing the bookmarks? Are the bookmarks stored in a folder somewhere on the drive?
