Spam Bot

I am the LAN Admin for a health imaging center.

Over the last week our public IP address was blocked twice by CBL. This pass Saturday I came in to the office to run Spybot S&D, Malwarebytes and to updated my AV on all machines. I also removed any unnecessary software from the machines. Needless to say that today in the morning I came to find out that once again our IP address had been blocked.

Is there anything that I could’ve missed? Any tools that the Tech Republic Community may recomend? What else can I do?

Thank you,
Dalton
