What do you mean by Firefox TCP ports. Also, where are you getting this info from?

I run netstat to a file before and after starting firefox and the following shows up.

TCP    Slowpoke2:4749         www-10-05-prn1.facebook.com:http  ESTABLISHED     1432    [ekrn.exe]

Should be fine. Just the facebook server connected to your computer

It is NOT fine, I do NOT want the facebook server connecting to my PC with out my permission.

I can assure you this is NOT a security issue unless you make it one. Do you have any third party Facebook software installed on your computer that checks your status etc? If so, and you are worried, remove it. If you are really that bothered about this, you can block the port in your router, if you have one, but that would mean you can't use facebook. If it causing you problems, you should do a scan for malware using a trusted piece of software. We recommend malwarebytes. If you want to know how trusted your anti-virus is, tell me the name of it.

Well you posted what your problem is... you are using ESET that is connecting to facebook... that's ekrn.exe! just uninstall (NOD?) or other ESET software...

dcbohn, Remove ESET. Then you have no problem.

Thank you for contacting ESET Customer Care.


This is basically how our web access protection works: ekrn.exe scans all IN/OUT traffic. The communication was started by other application and routed via ekrn.exe to scan for threats. This makes it looks like ekrn.exe was trying to access to facebook (or any other IP address) when in reality is another application. Unfortunately, it is not possible to figure out what application actually downloaded it. The only way would be by disabling Web access protection and see what app starts this communication.
