New! Security Center

Our Security Center page includes links to various resources that we have found helpful. These sites can help you learn about how to avoid security threats such as "phishing" and "spoof" attacks, viruses, worms, fraud, etc.

Note About Email Attachments

Colorado Information Technologies, Inc. technical support will never send you an attachment unless we have previously coordinated with you to expect it. Some recent viruses or worms are masquerading as an attachment from technical support or administration. You should delete any email containing an attachment unless you are expecting it. Also we usually use better grammar than the virus/worm writers do!
