Which free security software are best for Anti-Virus, Firewall, Anti-Spyware, Anti-Adware/Malware?

You may want to have a look at this thread. It is what The PCHF Security Team recommends in terms of security software:

Personally, I use Avast AV. It's registration is free. I also manually scan with hijackthis, ccleaner, and Malwarebytes anti-malware. I use firefox as a browser. From personal experience, internet explorer is just too weak when it comes to resisting browser attacks. Thats just me though.
