I use the Windows Firewall on my W7 system. I have never set up any of my own rules; nor have I added any product that creates them.
Recently I installed the latest version of CCleaner. In the attached picture you can see that CCleaner flags 12 invalid rules.
I haven't proceeded with letting CCleaner delete these items; and I was wondering if other CCleaner users have seen the same things. If not, does anyone have any idea what would cause such rule changes? Also, how would I go about re-installing a fresh copy of the W7 Firewall?
Thanks for any help offered.
