Like the previous poster, I don't write many reviews. But I just got my first email notifications from rsFirewall. What a great feeling it was knowing the it was doing it's job. All I can say is. Wow. The firewall is great. And the System Check is the best I've ever seen. What a great tool. My only suggestion is, be sure to turn on captcha and auto-blacklisting if you're using the email notification feature. Your email provider might not be so happy with you if you don't. Fortunately I was at the computer and quickly got it turned on when the phone started screaming. Lesson learned. Thanks again for a great product.
