Firewall blocked most of my ports?

Hi.

I just installed COMODO firewall yesterday, and since it started work strangely like blocking my applications and ports which is already in my trusted list, after a while I decided to uninstall it.

Then after I uninstalled it and restarted my computer, then I just noticed that most of my ports are still blocked, because my YahooMessenger can’t connect without HTTP proxy, and I can’t start my TeamViewer and other programs which need to use ports, but I can still browse webs and use FTP.

I was installed firewall and just keep Next and Next, I dont know what I done wrong with using it.

Please help me if anyone know about this…
