The Clean utility comes in form a small portable program called Clean.exe. It can also be used when the regular uninstallation goes through okay but still leaves behind some files and registry entries. It should be used only when the regular uninstaller fails. However, this utility should not be used as a replacement for the regular uninstaller. Using this Clean utility, we can completely remove all the ZoneAlarm products installed from a PC. But because of some left over entries the installer got stuck in the middle.įor situations like this ZonaAlarm offers an uninstaller utility called ZonaAlarm Clean. So I first uninstalled the product, rebooted the computer and then tried to install the new software. When I upgraded from the free version of ZoneAlarm Firewall and Antivirus to the paid subscription version of ZoneAlarm Security, I wanted to make it work right. And when they offers free antivirus with ZoneAlarm Firewall, I upgraded to their ZoneAlarm Security to enhance the overall protection against all kinds of online threats whether it is malware infection or intrusion into the system. Personally, I have been using ZoneAlarm Firewall for more than 10 years on my Windows computers. ZoneAlarm has been offering great security software for more than a decade.
