If running only 2 security programs real-time, what would you choose? I've been using Sandboxie and WinPatrol Plus together for quite a while, but last week I had a temporary issue with SB, so I loaded Prevex SOL with Private Firewall. I think those two made for a powerful defense. That got me wondering, which two-program combinations work well together? Edit: To be a little clearer, the question isn't so much to find programs for my own use, but more in general about how to think about security, the ways two different types of programs can be put together to provide the broadest security coverage.
