Antivirus softwares?

is it about all paid anti-virus softwares ( kaspersky, Nod32, F-secure, etc) are for one year only? so is it means if i paid let say $20 to purchased the kaspersky 6.0, then after one year of using it, i have again pay some amount to Renew it? so in this way, we are paying for our anti-virus software every year!!?? not that good. And by the way, i saw that CA eTrust antivirus is providing a free trail of one full year, is this software good enough? thank you

What you are paying for is a year of virus signature definition updates.

New virues are created by the "blackhats" every hour of every day of every week. The anti-virus software vendors must issue new definitions several times per day in order for their programs to catch these nasties.

However, there is some decent 100% free anti-virus apps.

I use AOL AntiVirusShield. Don't let the name AOL fool you. AntiVirusShield is made by Kaspersky which is one of top-rated anti-virus vendors in the world.

In recent tests, the most popular free anti-virus, AVG, was only able to detect about 82% of a very large sample of viruses. On the other hand, AntiVirusShield was able to detect better than 99% in the same test.
