I would add SpywareBlaster which is similar to real time protection in that it protects you while you surf.
Of course use the firewall. Be sure to see "allow an app or feature to pass through Win Firewall" + adjust as necessary.
If you have a router/gateway set it to WPA -2 with a strong internal password or key.
Also, I would use MBAM or MalwareBytesAntimalware which is a good malware scanner if kept up to date.
There are many combinations but this should keep you secure if you use the web safely.
