Yes avibky, what Alpha say is true. Go with Comodo Firewall, its the best firewall out there with minimum memory usage. It won't slow down your uncle's pc. But, be aware that Comodo Firewall is not available as a separate component. So, you have to download Comodo Internet Security and then install it. While installing it asks you if you want only Firewall or Internet Security or Antivirus. Choose Firewall and you are done. Have great time with Comodo By the way, set Comodo to Training mode for first week, so that your uncle won't be confused by the alerts it give...
