CA Internet Security 2007 (Firewall Issues)

Well, im having a huge problem with my computer and my internet.
Its going to be hard to explain whats happening, so first, i will say what was going on before I removed my CA Firewall.

(*) -Everytime I went to the internet, most of the websites images didnt open, it was that little paper with a red X in it.
(*) -Everytime I tried to go to IRC, update another software, it wasnt connecting, same thing with Online Games.

Altough, when I turned the CA Firewall OFF, all of those issues were gone.

Now, about 3 days ago, I removed it, but since then, all of those problems (*) continue just if the Firewall is ON, and my computer is mostly unusable.

I have tried everything i know, delete every file related to CA, clean the registry, antivirus/anti-malware diagnostics, went to safe mode, and did every diagnostic again and nothing, but those problems are still going on.

At this moment, im trying to reinstall CA Firewall, but, for some alien reason, i cant reinstall it, I have the CD and everything, but when I try to install it, there is a message (Warning W9011) saying that the current profile doesnt have enough privileges to update a key in the registry called .efw and telling me to log in as administrator, but im already in an administrator profile.

I cant stand these problems anymore, so I think the best way is to keep the CA Firewall, if you guys could help me install it, I think its enough.

Thanks alot, and I will be here waiting for your answers! ;)

Thanks for not answering. Help next time k?

1: Run CA Firewall again and write in a paper the exact location of the warning. (Something like HKEY_LOCAL_MACHINE\SOFTWARE\Classes\*.*\*.efw).
2: Close the program CA Firewall.
3: Run regedit
4: Found the location, right click and select permissions.
5: Included your user with Full Control.
6: Select Apply.
7: Try Again to install the program.
