In all honesty you are preaching to the converted, those that need the help generally don't read anything about securing their system.
As Bob3160 said you don't need to go all paranoid to protect your system, good antivirus (avast of course) good firewall with outbound protection, your browser (running as limited user or sandboxed). You can add other things anti-malware to compliment your AV.
If you spend lots of time keeping your security up to date, you become the slave to it rather than it being your slave.
A healthy dose of common sense and suspicion is very important too. But above all else (for when the dark brown stuff hits the fan) a robust backup and recovery strategy, hard disk imaging software, run regularly and you can recover form all manner of issues (not just malware related).
