It may have undesired effects but if you block login.passport.net you may have good luck.

I can send a message from uscellular.com if I enter my cell phone number and the number of the phone I want to send to. If you can find out the web site(s) they are sending from, you can probably add the site(s) to your firewall. I assume you are not talking about Instant Messaging like MSN Messenger, Yahoo Messenger, or AOL Instant Messenger. I have those sites blocked with my firewall already. There are probably others, but I have not found any that install on the local machines. Brian Ney N.

Any suggestions on how to block this little activity. Thanks, Linda Linda Huseman Technology Coordinator Alta Community School
