Because we have had significantly fewer problems with Macs, we do not have a site license for any antivirus software for the Macintosh. We do have several copies of Norton AntiVirus 7.0 available for use by staff members upon request. We do not provide copies of antivirus for student-owned machines. Students who feel they need virus protection beyond the precautions listed above should purchase antivirus software. Norton, Sophos and McAfee maintain antivirus software.
