In July, the campus implemented anti-virus filtering for all email processed by the campus central email servers. Under this new program, about 20 million email messages are inspected each month. Those messages with virus attachments are identified and deleted, and a deletion notification is returned to the apparent email originator. This notification is accompanied by a suggestion that the source computer be inspected to ensure it has not been infected by a computer virus. Initial virus statistics revealed over 50,000 virus-infected emails identified during the implementation month of July and over 130,000 in August. Starting in late August, IET extended email anti-virus services and software to campus units that operate independentemail servers. Campus units may also choose to independently acquire and install anti-virus software for unit email servers. Several campus units have taken this approach for some time.
