Among other things, I have installed Betfilter on every computer he has access to (see the discount code for GT members in the column to the right), I have a lock on our home office door where I keep valuables and anything financial (jewelry, coins, silver, my laptop and iPad and anything else that can be pawned, blank checks, car titles, etc.), I installed a locking mailbox so checks and credit cards no longer disappear, and I enrolled both of our Social Security numbers and all of our accounts with LifeLock for identity theft and credit protection.
