Firewall Strength

Hi, Can someone please advise why the strength on my Comodo Firewall has suddenly gone to ‘Bad’ and all options on the main window are showing as ‘Off’ & won’t let me turn them back to ‘On’ and how I can get it set back to ‘Full strength’ so that I can access Internet explorer again?

Thanks

Mark

It is possible some files may have become corrupt. I have had this issue before in the past and uninstalling then re-installing fixed the problem.
