A Firewall Question
 

Type the "remote host" values into your browser and see where they take you. Most likely something you have installed is trying to update itself.

I randomly checked a few of the remote hosts and they all lead to an identical page titles "Apache 2 Test Page
powered by CentOS"

ntoskrnl.exe does not appear in the process list though.

Another strange thing that I noticed, is that the firewall sometimes tells me that my Firefox has changed, even when I haven't updated any new extensions. http://www.discussworldissues.com/fo...smilies/hm.gif

Another question, is why programs have lots of line?

Go to Log Viewer, Security Log.
Click on a line and run Back Trace Whois.

Is this your ISP? Tecnicos Telefonica de Espana.
If you don't recognize, maybe you should utilize that abuse mailbox. Or do a Google and then report, or not.
