Hello,

I keep getting these pop-ups:

Code: [Select]

Why is IE doing this ("trying to listen for connections from my PC", "trying to connect inside my PC")?
What are the port numbers needed for?
Thanks,

Do you have Spybot S&D?

Hi,

Thanks for the answer.
I've read the link, and i do have Spybot, which explains the www,007guard,com reference. Now I've changed my first line in my hosts file to be

Code: [Select]

127.0.0.1       localhost
. As a result, the messages i get look nicer:

Code: [Select]

...
Local Address: localhost 57397
Remote Address: localhost 0
...I still wonder, though, and pardon if it might be a noobish question, what is IE (and any other program) using the loopback mechanism for?
Thanks again,
amba

K. what I've found so far:
the loopback mechanism is normally used by software. the software is "talking to itself".
these connections (127.0.0.1) cannot be reached from outside the computer. (source http://forums.mozillazine.org/viewtopic.php?p=3222661 )
On Firefox, for example, the loopback mechanism is used to set up an SSL connection.
I wonder if this have to do with the "client-server model" application architecture.
Have a nice day,
