I have tried to install ZoneAlarm firewall and never managed to. I ended up with a downloaded file without any extension, and Windows did not know what program to open it with.
So I set my choice on Comodo firewall, and installed it successfully.
However now "ZoneAlarm Free" appears in my list of Add / Remove Programs, and it says it occupies 60.0 MB. If I click on it to remove it, I get the error message
ZoneAlarm cannot be installed on a system already has COMODO Internet Security installed.
Your system doesn't meet the installation requirement.
That message also appears at each restart.
There is no trace of ZoneAlarm or "Check Point" under Program Files, and it is nowhere to be found on the C drive. I have used 2 search programs and searched for file names and folder names.
I have used CCleaner to rename the ZoneAlarm entry in the list of Add / Remove Programs, but that hasn't changed the situation.
I COULD use CCleaner to delete that entry from the Add / Remove Programs list, but I am reluctant to do so, because there is obviously more than just the actual entry.
What would be your advice?
