If you are wondering why you shouldbuy an antivirus program then you should probably ask another question first : what happens if you don't?
Well, a lot of that will depend on how savvy a computer user you are - I have a friend or too who claim they have never had a virus despite not having any security software installed.
(And, no, they are not Mac users before you make that suggestion!)
The average person, however, is not likely to be anywhere near as fortunate as that because there are something like 200 new threats created each and every day - viruses, worms, trojans and all sorts of other nasty surprises await the unprotected.
Would you like one of those malicious programs on your computer?
No, I didn't think so.
The answer then is to find a security product that can protect you from not only the current threats on the internet but also the new ones as they are created and released into the wild.
An antivirus program is what you need and you have two real choices here - a free antivirus program or one that you pay for.
Both options will afford you some level of protection but I would always recommend paying for your protection unless you are a very casual user of the internet.
Free antivirus programs can protect you but the paid for versions tend to offer a better level of protection in my opinion and are generally updated far more often.
Which antivirus program should you buy?
Well, theres no easy answer to that as we all have our own skill levels and needs but you should choose a reputable company in order to get a quality product and also to avoid some of the rogue security software that is being sold these days.
The latest antivirus program that I have reviewed - F-Secure Antivirus 2011 - is effective and easy to use but I would suggest checking out all my antivirus reviews through the link below.
