Some advice please on windows being blocked.

HI,
I have noticed in my firewall logs that windows operating system is being blocked from receiving an inbound echo request connection.
Does anyone have any ideas what this is and should it be allowed.?
Comodo firewall was blocking this at installation.The picture below may help.
Thank You.

 

Have you tried using a search engine?

Yes i have used a search engine thank you and no clear answer seems forthcoming.
I do not use torrenting software of any kind and all file sharing is turned off.
I would like to know why the operating system is requesting an inbound connection.
The BITS service is running even though i should turn it off.Ive browsed the comodo forum and it seems a common occurance so i am going to leave it as it is.
There was a request from port 445 from MS-DOS when i first installed comodo but i blocked this.
Thanks.

 

Normally echo request ICMP's are blocked, especially if you don't run a server or share files. Echo replies inbound you can allow as well as echo request outbound ICMP protocol.

 

Thank you for the reply.Much appreciated.

 

You're welcome
