"Antivirus protection is very important, and should not be taken lightly. Here are some of the pros to both the Avast antivirus, and Norton antivirus.Avast - provides advanced features, such as anti-spyware, anti-rootkit, and self-protection to prevent malware from turning off the Avast security. Avast has received 100VB awards for catching 100 percent of the viruses sent to attack a computer.
. Avast also has an advanced feature, that protects you from peer to peer (instant message protection), so you won't accidentally download a link to a virus. There are a lot of advance features, but may be more difficult to download and understand due to all of the features.Norton - is the most commonly used, and they have improved the Norton 2009. Before, the Norton antivirus was large, and slowed down your computer, but the 2009 version has been ""lightened"" up to prevent this problem. Norton is rated higher in the malware protection, but also provides the IM protection, but is rated a little lower (by 98 percent) for these protections"
