How well will this work? Some people say it doesn't work at all, while others swear by it. I dont know much about ips and protocools and stuff, so your feedback would be great. I currently am using it, but only when downloading. Should I only run it when downloading, or constantly? It blocks quite a few websites when I am surfing (while not DLing), so I usually shut it off. What do you guys think about the program?
