I know, we've done this before, but possibly not exactly like this. So please play along. Let's suppose you have NOD32 installed and your favorite firewall whatever that may be. Let's also suppose that for whatever reason, you can only install one more security program. This program will need to protect you from spyware, trojans, rootkits, or whatever may get past NOD + Firewall. So if you could just install one other program, what would it be and why?
