Does anyone know how to uninstall Zone Alarm free from Vista Home Premium?

I had problems installling it with messages from True Vector or something, but it finally manaaged to install - now I want to put Comodo Firewall on - i'm a bit concerned next time Zone Alarm wants to update new version, I will have problems.

Hi Paulrenno,

Do NOT remove from Add/Remove programs as it will not uninstall properly.

Make sure you have Administrative rights. You may have to confirm through UAC.

Go to Start, Programs and then Zonealarm.
Find the entry for "Uninstall" and RIGHT CLICK it.
Select Properties.

In the path go to the end of the line and add this: /clean (make sure there is a space between the last character and /clean)
For example you might have:
C:\Program Files\ZoneAlarm\Uninstall.exe

Change it to this:
C:\Program Files\ZoneAlarm\Uninstall.exe /clean

If you want to remove your license information as well then use this switch:
C:\Program Files\ZoneAlarm\Uninstall.exe /clean /rmlicense

Note that the line may not show exactly, but it will be similar.

Now Click, Apply and OK.

Finally, Go to Start, Programs, Zonealarm and select the uninstall option to completely remove Zonealarm.
**Important** REBOOT the System.

Delete the following Folders if they still exist:

C:\Program Files\Zonalarm (folder)
C:\Windows\Zonealarm (Folder)
C:\Windows\Internet Logs (folder)

Empty your recycle bin.

That's it!

Thats great .. thanks a lot for your help.
