Install antivirus software

ESET Antivirus

The Antivirus solution provided for Mac users at CERN is ESET Antivirus. It is available from the Mac Self-Service. You can install it over Microsoft SCEP, the ESET installer will remove MS SCEP if it is installed.

ESET Antivirus is for Macs that are predominantly at CERN. For Macs that spent a significant time of the year at your home institute please use an anti-malware solution provided by your home institute.

For your Mac at home we recommend one of the free AV products. Please note that the licenses for most of the "free for home use" products don't allow the usage of the product in a profesional context. So if you use your private Mac at work these products are not covered by a "free for home use" license!

Instructions how to exclude TimeMachine backups disks from the ESET scans can be found on

The ESET installer will not remove any version of Symantec Endpoint Protection or Symantec AntiVirus. If you still have any version of these installed you need to remove them before installing ESET Antivirus by following the instructions below.

Microsoft System Center Endpoint Protection (SCEP)

Microsoft has stopped the support for SCEP for Mac at the end of 2018. SCEP for Mac is not compatible with macOS 10.14 or newer. If you have not yet upgraded to macOS 10.15 Catalina you can use the uninstaller provided by SCEP under

/Applications/System\ Center \ Endpoint \

or for friends of the command line

/Applications/System\ Center \ Endpoint \ .

This does not work anymore on macOS 10.15 or newer.

Symantec Antivirus

Symantec Endpoint Protection for Mac was decommissioned in February 2016.

The versions of Symantec Endpoint Protection, Symantec Antivirus and Norton Antivirus previously provided by CERN contain critical vulnerabilities and should be uninstalled immediately.

Free Antivirus Solutions

Many vendors offer 'free' versions of antivirus software for 'personal use'. Please note that using your private device at CERN is NOT considered 'personal use'. Do not use these 'free' products on site. Carefully read the license conditions before using such products on your device at home.
