Many people have been looking for the best anti-virus software in the world. But I have to say that nothing in this world is perfect. Well, yes we do have best software, but bear in mind it is not a perfect product. It doesn’t mean that it can detect ALL viruses.
One question though, do we actually need a anti-virus software for our computer? For some experts, they claim that they don’t need anti-virus to protect their computer. Is it a necessity to have anti-virus? I’m not so sure whether it’s a necessity or for a peace of mind.
There are few great freeware anti-virus, AVG by Grisoft, Avast! by Alwil Software (Personally used myself), AntiVir by Avira and etc.. These 3 are the most common freeware on the net, there are also free virus scanner for users like TrendMicro, Kaspersky and etc.
I would say that, the best prevention from getting infected by virus is your brain. Why I said so? Very simple, to get infected by virus, what you can do is by clicking blindly in the junk mail, or simply download a warez on the net and that way you will have a very high risk of getting infected.
