Install and Use McAfee VirusScan on a Mac OS Computer


The University uses a licensed copy of McAfee VirusScan customized for employee-, student-, and University-owned computers. Some programs conflict with McAfee VirusScan. If your computer has other anti-virus software installed, you must uninstall the programs before installing McAfee VirusScan. Common anti-virus programs for Mac include—but are not limited to—the following:

  • Any pre-installed McAfee product (NOTE: You should remove McAfee copies that are from sources other than the University of Delaware. For example, a promotional copy that came with your computer, a copy that you purchased with a retail license, or a copy from a previous school or employer.)
  • avast!
  • Bitdefender
  • ClamXav
  • ESET Cyber Security
  • F-Secure
  • Intego
  • Kaspersky Internet Security
  • Panda Antivirus
  • Trend Micro
