My system told me that I had a firewall but I don't know what firewall it is?Can anybody teach me how to detect the firewall and delete it because certain programs
I can't open as the firewall is blocking it. Are you the only user of this computer?
If not, ask the other user(s) about what firewall is INSTALLED.
If you're the only user, then it's unlikely that you have installed a firewall without knowing it.

What OS do you have? Windows XP? If so, and you have Service Pack 2 installed, then you would have Windows Firewall on your computer.

It's never a good idea to get rid of a firewall because it helps keep you protected.

What programs are being blocked? With a little more info, perhaps we can help you understand how to use the firewall so you can allow certain programs to run.I think I installed the Symantec firewall recently and sometime I disable it when it startup.But it still does not work I am using Win Xp home but EVERYTIME I try to execute the program it does not work it tell me to send the report to microsoft and I tried to remove it out of my system but to no avail.I also disable the windows firewall but still they told me that other firewall is still on.So the symantec firewall I deleted everything from its file so what is wrong?Let me get this straight...do you mean you are getting error MESSAGES like the one in the attached image?

[cleaning up - attachment deleted by admin]No.But what is wrong?I know a firewall is used to block unnessary stuff but I was just planning to use windows firewall after deleting the it as some of the programs I am trying to use cannot connect to its server.
Go to the Control Panel

There you will find "windows firewall".

Open it, what does it say.It is currently off.But the idicator is still saying that I got some kind of firewall use.Which indicatorThe Windows Firewall indicator it says that Windows detected one or more firewall running but I already close the Windows firewall already!And you don't know what other firewall(s) you have active? You can post a HijackThis log, which would show us any active firewalls (besides Windows Firewall). There are other methods, of course, but this is my preference.
