A co-worker was surfing the web, and it installed a Trojan that send thousands of emails within a short period of time. Needless to say, our IP address is blacklisted by:
Connection refused due to abuse. Please see http://mailspike.org/anubis/lookup.html
My question is, what do I need to do, at each computer, to prevent it from sending mass e-mail messages? Currently Symantec EndPoint Protection is running on all computers, and the co-worker did receive a "warning" from Symantec that a trojan may be running and sending out e-mails on a proxy server.
By the way, I have submitted a request (at least 8 times) to mailspike to delist my IP address.
Thanks for your help!
