I did in fact install v4.1 a few days ago after first following the instructions to disable protection, uninstall the previous version and then install v4.1. Then, after receiving all the updates for v4.1, it took about 30 minutes to enable all protection. (The same problem occurs on 2 separate PC's.) This seems FAR too long a delay to enable all protection. Any thoughts on what may be causing it and how to fix it?
