A high anti detection rate is perhaps the best quality that an anti virus program should have. It is absolutely necessary as it keeps the terrible viruses far away from you computer and files as well as getting rid of them immediately.

ESET NOD32 Antivirus 4 is the highest rated in the world of anti virus programs. Both Norton programs are well reviewed, and in some cases exceed the ESET NOD32 Antivirus 4. Although prevention is standard on the ESET, there is no firewall included. It does work well because the prevention rate exceeds all other programs. Although it has a high prevention rate, both Norton programs boast a high detection rate, higher than ESET. There is not a large difference between the programs, so key decision cannot be based on this criteria alone.

Another important thing to make sure your software has is compatibility with your system.The last thing any one wants is to pay for a program that keeps deciding parts of your Windows XP are life threatening viruses, or worse, shutting down files or desktops. ESET NOD32 Antivirus 4 is the best choice in this category, since it has absolutely no software conflicts. Norton Antivirus 2009 is the worst in this category, having multiple conflicts with Windows XP, a heavily used system. Norton Internet Security falls in between the two, but it does have a plus in that it does not conflict with any other protection software you may have installed.

Other factors to include are ease of use and speed. All of the programs boast high ratings and good reviews in both of those categories.

Today, a lot of people are forced to factor the price of their purchase into their decision. Norton Antivirus 2009 is the best of the lot, starting at a low twenty dollars. ESET NOD32 Antivirus 4 is more expensive at thirty-five dollars, although it comes in a little lower than Norton Internet Security’s forty-five dollars.

Comparing the leftover negatives of the software can be a big help to the undecided. Although Norton Internet Security is priced high, it doe not have the spam protection and technical support that one would expect. Norton Antivirus 2009 fares the same, suffering from a lack of good tech support.

While looking at a comparison of the top three anti virus firewall software programs, the most important thing is to know that every one has different needs and requirements from their anti virus software.
