Tried the Comodo Free Firewall software on my laptop after reading great reviews on it today, and 2 thing stuck out right away. One, it seemed to add 3 or 4 extra icons or actual extensions of the program on my desktop, some virtual search function, another was a test of files(?), and it also had a small window in the upper right hand of the desktop screen with a status of the program that only went away if I opened a web page. Is all of this "normal?"
Second, during the install process it asked me to allow it to make changes to DNS servers, which is a bit beyond what I know. I did read the link that said what is this? And it seemed legit, so I allowed it. Soon thereafter my son tried to use our XBox that uses our home network to connect to. He was unable to connect to the network or internet, and I believe that this in some way was related to the DNS change that Comodo asked me to change. I could be wrong, but I think it's all related. Is what I described the normal process/end result of using Comodo Firewall? I went and uninstalled it once the XBox issue became known.
