I am just curious… what can you say on the quote below: “@John: a good firewall makes a system perfect? oh dear.. I dont run a firewall, and never have done.. I kinda got a bit of a mental block about the whole process of opening up a dangerous port then having firewall software pester my cpu and have it look at every packet that comes through.. better to just close the port.. prevention, not cure ” It sounds interesting, isn’t it? Is it really possible to be safe without using a firewall? Of course there’s no reason not to use one coz there are lots of available free programs out there and topics and forums that talks bout firewalls. But… how about if one chooses not to use a firewall? What’s the best alternative that you can suggest… and how can we close all those vulnerable open ports? Can we considers Windows Worms Doors Cleaner (WWDC) of gkweb just enough to close those ports?
