I recommend an interesting program named Peer Guardian
especially if you are doing any P@P downloading and sharing.
I installed this last evening and have been running it.
It has shown me, and blocked access to my computer downloads, by a most interesting group
of organizations. I was really surprised who was curious about my internet activity.
The program is free and doesn’t seem to use much in the way of resources.
Once you install it, look at the “Log check” section and click on the “Blocked tab.”
This will show you who has been trying to see what you’re dl’ing.
Also, be sure to do an “update” several times. It sometimes takes more than 1 try.
I set mine to update everyday - but I still do it manually just out of curiosity.
