I just want to know if I can install the latest version with Windows XP without any serious problems. The reviews at download.com were mixed wth some people saying not to install it. I'll be using it with a dial-up connection. I don't know if that matters. The description at downloads.com said it's a firewall for high-speed connections or something to that effect. I use an old version and don't have any experience with the newer versions. Thanks.
