Norton AntiVirus 2010 is the best-selling security solution with a complete set of features the mordern antivirus is supposed to have.

Kaspersky Antivirus 2009 provides comprehensive security and some new features. Kaspersky is one of a number of brands in the Anti-Virus and online security market that is growing in stature due to product improvements.

On the other hand, if you’re unlucky, then it can easily mean the freezing of software, an increased number of errors and, eventually, fatal errors that lead to the crashing of your computer. Unfortunately with some anti-virus applications it may not be your fault that your virus definitions do not cover the latest threats.
