There are several very good anti-virus programs available right now, and Norton AntiVirus is one of the best. A Mac version is also available. Symantec, the manufacturer of the Norton products , has always been a leader in the virus protection business. They recently formed an alliance with IBM that also puts the powerful Thomas Watson Research Center in their research corner. Norton AntiVirus has the ease of use that I look for in a software product.
Installation is quick and easy.
During installation you are asked to make a set of emergency rescue disks, which will help you to recover from a virus that may leave your computer incapacitated. After the program is installed, you are prompted to immediately update your protection. The heart of the Norton AntiVirus program is its scanner software. The scanner searches your computer files for various types of viruses, which can be identified by behavior. It also protects the computer against the viruses that are in its virus definitions, which include all the currently known viruses.
