I assume you have the firewall set to “safe mode.”
First, it’s up to you to determine if Nextprv is really a “safe” application. Comodo keeps blocking it because it doesn’t consider it safe. If you feel it’s “safe”, delete the blocked rule Comodo created and manually add C:\Program Files\NPVR\NextPVR.exe as a trusted application.
The firewall doesn’t automatically block applications, it will prompt the user to allow or deny access, even if the application is unknown/untrusted. If something is unknown, the sandbox, if used, will intercept the application/process.
The funny thing is that Nextpvr.exe is added as a save application with allowing all questions and still this is blocked.
Post a screen shot of your Application rules.
There are also two network zones created:
loop back zone 127.0.0.1/255.0.0.0
And the network zone:
127.0.0.1 is loopback and 192.168.1.10 is your LAN. An entry in Network zones means nothing unless it’s actively used in a firewall rule. Other than that these entries are just informational.
In a default installation of CIS with the firewall and D+ in safe mode, get two firewall prompts and several D+ alerts. If allowed, two generic rules are created (see images) when you receive a prompt are you allowing or denying?
Many thanks for all the replies. I discovered the problem and solved the problem . The problem was not Comodo firewall but the service of Next-PVR was not up and running. I was pushed in the wrong direction by the log of Commodo which told me that the NextPVR.exe program was blocked with source IP 0.0.0.0:3640 and destination Ip 127.0.0.1:8968.
After starting the service of NextPVR.exe the program worked fine.
