That's exactly what I thought. Until I gave it a try. Free spyware, antivirus, and firewall software will probably give you the same thing as the paid ones do. By getting free pc security software your only getting the "core", which means you won't get customer service, or any bonus software you might get with paid pc security software. I think, with all respect, you are wrong to believe that paid software will do a better job than free ones. I tried the mcafee software suite and it just gave me problem after problem and it wasn't doing a good job. So, I got the free AVG antivirus and it works a little better than mcafee. Guess how much I paid for AVG, NOTHING, FREE!! You can try spybot-search&destroy for spyware as well as Zonelabs for you firewall. With all three of these software I guarantee you will be virus and spyware free. I don't know if you've heard this or not, but they say "The best things in life are free." I think it's true. By going free you gain the fact that you don't have to pay. With AVG Antivirus you can only scan and get rid of the viruses. AVG also has AVG Internet Security Home Edition, this is $64.95 for a 1 year Subscription. I took the following from their website:

See what I mean with the free version you just get the antivirus, you can also download an anti spyware from avg also.
They make their money from selling software. For example AVG sells the AVG Internet Security Home Edition for $64.95. They make the free version available so you can eventually buy the Home edition. Spybot does this too and they also accept donations, Zonelabs also does this.
Their is no catch it's just like a marketing strategy to get people to eventually buy their software. But hey it's FREE, and that's good enough for me. In my opinion their is no difference between free software and paid software. If you have a very good understanding with computers and your on a tight budget then I suggest you get the free version. If you do not have a good understanding with computers and you have the money then I suggest you get the paid software because they have technical support available. I hope this helps you.
