I am very disgusted with my knowledge level. I have tried many firewalls and have learned that they all get turned off. The latest was Comodo with the message click to fix me, but no explanation as to why or how to prevent it again. Is a firewall even needed, especially since I haven’t found one that consistently works? Also is it normal for Avast to now report that the files that it put into its virus chest are now without virus? Thanks. (Sorry, I do not know if it is Avast, or for that mater what is causing all the cameras to not display and for that mater, even the expert after 8 hours of trying. Just expressing some of my frustration. Avast and all firewalls never blocked the cameras before.)
