Hi, I am a long time ZA free user but I am using it on Windows XP. I have never had a problem and really love ZA free and hope to continue using it. But I am considering getting a new pc and so will have Windows & 64 bit and I was not sure if the older versions that work with XP will work with Windows 7 64 bit. I did not think they did and if so what would be a good version to use with Windows 7 64 bit? I want the free firewall only and not any anti-virus or anything else. Is that still possible? As it looked like the current version included anti-virus but I thought an older version may not? Also does ZA free for Windows 7 64 bit still work and look similar to the older versions for XP? I hope so or similar as I always felt it was so clear and easy to use. Thanks in advance for any help.
