In July 2002, IET added email anti-virus services to the campus central email servers. The servers are now filtering between 15 million and 20 million email messages per month for known computer viruses and identifying approximately 200,000 virus attachments per month. This filtering has resulted in a decreased loss of data along with productivity gains as faculty, students and staff devote less time to virus removal and restoring computer systems. For more information on this anti-virus email filtering service and other virus-related topics, see the Security Web site at http://security.ucdavis.edu/
