How many security programs should you have on your computer?

I am completely technology illiterate and I don't know the difference between firewall protection and antivirus protection and spyware protection and whatever other type of protection there is out there! If you would please explain the diferences to me and tell me the ones that I should have on my computer. Also, the security program I have on my computer is fixing to expire so if there are any good security programs I can download for free that would be greatly appreciated as well!

You need a really good anti-virus as well as an anti-spyware program if you download anything from the internet. I can highly recommend the following as I have been using them for years without a problem. Kaspersky for anti-virus and CounterSpy for the other. The standard Windows firewall is enough if you have these two.
