I had already ZoneAlarm free firewall and Avast 6, but when i uninstalled firewall, and try to reinstall it won´t let me.
Here is the message:
ZoneAlarm cannot be installed on system already has AVAST Antivirus installed.
Before it worked very well together.. What is the problem now..?
This sounds strange, uninstall both ZA and avast 6. Make sure there are no other software firewall or antivirus are on your computer.
Reinstall ZA, restart your computer.
Reinstall avast, restart your computer. I'm assuming your using avast 6 Free Edition.
Oops! I should've told you to download the avast! uninstall tool and run it.

My fellow avast! Evangelists should've reminded me.
http://www.avast.com/uninstall-utilityZA has a built-in uninstall tool that runs automatically whenever ZA is uninstalled.

Sometimes software becomes corrupt, it can happen to any software.
It's good to run a software's uninstall tool (if there is one) whenever you uninstall or re-install software.
Doing so can reduce problems.
I think it would be a good idea if avast! would follow ZA's lead in including a built-in uninstaller that runs automatically on uninstall.
