It's tough getting users to make backups at all, let alone adopt a strategy that's robust.
Personally, I create/update drive images every 10 days or so and keep them offline (but that's primarily the OS partition, not vital documents and files, which I image/update monthly), run continuous backups to a MyBook (which I need to start backing up to offline storage on a regular basis real soon now and otherwise keep offline most of the day), and automatically create backups of just my most critical files to my DropBox account every 6 hours. So I am not doing such a good job myself when it comes to back-up strategy.
I run CryptoPrevent, CryptoGuard and CryptoMontor (which is purported to be crypto-robust) and use Avira as my A-V but hope I never have to say I wish they did a better job of protecting me. I'm also cautiously starting to check out RogueKiller, but it has a tendency to be over-zealous with killing tools I use for computer repairs. The more I think about it, the more nervous I become and the more naked I feel.
