For a few months, I have had the problem of not being able to disable my Comodo Firewall at all when I want to download a programme that it might prevent installation of. I can click on the dashboard and select it to disable, but it has a rather strange looking reaction when I do that, hard to describe, just sort of blacking out part of the dashboard temporarily and then it gives a popup asking how long I want to disable it. When I attempt to select one of the options, or even just click the button to go ahead with the default option, it will do nothing at all. Is there a way around this other than to remove it altogether and start with a new download of the firewall? I don't even know if that would work since it won't shut down at all and always comes on when I start windows 7.Please note, I am not extremely tech-minded, so would appreciate it if any explanation were simple and stepwise. I would really appreciate some help with this. Thanks.
