I just updated to the latest version of Comodo, and when it asked me if I wanted to use Comodo Secure DNS Servers, it sounded like a good thing so I checked it and now, once it reconfigured my home network settings, it is telling me that Comodo Application Agent isn’t running. I have clicked on the diagnostic button twice and it says the installation was successful, so now what do I do to get the application agent running? ARRRGGGH!
From what version did you update? How did you update? Using the program updater from within CIS or run an installer?
Do you have other security programs running in the background? Try disabling them reboot and see if that helps or not.
What OS are you on? Are you running as administrator or limited user?
