I know there was a recent thread along these lines but as a newbie to firewalls I was not sure what the final conclusions were as replies were rather mixed. I hope the questions I list below are not simply repeating the previous post! I have recently moved house to the 'sticks' so I have only a slow dial-up connection. However, I should be connected to broadband/cable in a couple of months. Further, although I have 2 computers, one of which is a laptop, these are not networked together (I will get round to this!!!). Overall, I have been led to believe that a software firewall is only of use if you are on a cable connection and your computer(s) is on a network. My major concern is keeping my personal details such as credit card numbers safe from potential hackers, particularly as here in the UK, some banks and credit card companies are now telling clients they must use a firewall as part of any new contract. Therefore, 1. Is a software firewall of any use on a dial-up connection? i.e. do I need to use one at the present time? 2. Even when I switch to the faster cable do I need a firewall if none of my computers are networked? 3. I have a couple of AV programs; do I need a separate AT program to take care of possible trojan attacks or will the software firewall take care of this area of defence? 4. Would I be better looking at a hardware firewall rather than a software firewall?
