Computer virus are running rampant throughout the computer world with hundreds being added to the mix monthly and you need to be protected. Preferably sooner rather than later as an ounce of prevention is worth a pound of cure. Preventing a virus is easier than removing one. Everyone wants FREE, but when it comes to virus protection you get what you pay for - or don't pay for. Sure, for a free anti-virus program, AVG is OK but they are not as effective as some of the paid counterparts. The product that I have recommendend to all my clients over the last 5 years is ESET's NOD32 Anti-virus and Smart Security. They have 2  different products that you can purchase at very reasonable and affordable prices. Below are some of the reasons that I give NOD32 a high recommendation:

ESET protects you better against unknown threats
