People often ask me what kind of antivirus protection and firewall protection I use and recommend. Currently its Norton Internet Security 2010. Of all the popular ones available out there for individual consumers to use, it provides the best balance of features, stability, protection and just as important - it doesn't bog your system down.

Also even for the one user license version, they give you three activations. All expire at the same time, but that's three times the protection for the price for you people that have more than one computer system on the internet.

If you have more than three computers that need protection, they also have a 3 user license version as well.

Also, I recommend that you not do the yearly additional updates. Buy a completely new updated version and uninstall the old version before you install the new version. For example, if you have Norton Internet Security 2009 - uninstall that first. Then buy and install Norton Internet Security 2010.

Corporate customers should look elsewhere though. Their corporate network wide protection / antivirus just isn't as up to date as their consumer software.
