Not only about anti virus, in any field people always look for free. If some thing is available freely than why to spend money on that thing. There are many kind of free anti virus softwares available on the Internet. Have you ever think how effective these softwares are? Are these softwares as good as paid anti virus softwares.
Of course not. If free antivirus softwares are as good as paid then nobody purchase paid anti virus softwares. Free antivirus softwares are lacking in many features. They just provide the basic protection of the systems. Free antivirus softwares are just a medium for company to promote their paid version of anti virus softwares. So definitely they are not going to provide full functionality in free version.
Free anti virus softwares are lacking in following features.
First their virus database is not as good as paid version of virus database. They just provide very basic level of virus database definition.
Free antivirus softwares are not providing real time scanning. Well some softwares of course provide real time of file scanning, but they don’t provide real time of web traffic scanning and Internet is the main source for getting your system infected with viruses.
No free antivirus software provides firewall protections. Firewall is also a main component for securing systems on the Internet.
There is no technical support available for free antivirus softwares. You need support if your data on computer is cirtical and your system is infected with virus.
No anti-spyware, anti-spam and anti-rootkit available in free version of anti virus softwares. You might need to install free version of anti-spyware and anti-spam softwares. As a result your system becomes damn slow. And that makes your system so slow that even some of viruses can’t make is so slow 
.
I highly recommend investing some money in anti virus software if you are using your system for work purpose. If you are using system just for playing games and just for entertainment purpose then free anti virus is a good choice.

Jon,
You are the first one to make a comment on my blog. I just want to say thank you for that. You can actually install firewall but it will make system performance even worse. This is just my personal opinion. I actually prefer to have one good anti virus software instead of having many single component softwares.
Enoch,
