Hi Cheater
This is copied from Zone Alarm help manual

Upgrading from a previous version
Zone Labs security software is designed for easy upgrade from version to version. In most cases, you do not need to uninstall your existing version before upgrading to version 6.0. However, if you are using any version of Integrity Client (for enterprise use only), you should first uninstall that product before upgrading.

also taken from how to install
If you have a previous version of Zone Labs security software installed, you may receive a security warning during installation. Click OK to dismiss these warnings before proceeding with installation.

 

if i have mine automaticly update does it update to the newest version?

 

I believe it only updates the signatures automatically
and if a newer version becomes available it informs you and provided you have a paid up subscription you can upgrade it free.

 

i have the free version

 

Well you should have no problem upgrading for free
