These files are Windows-only. We currently do not have a version of McAfee for Macs that does not significantly impair system performance.

McAfee Anti-Virus (usually just referred to as McAfee, the name of the company) is a commercial virus scanner that Carleton provides for all students, staff, and faculty. Carleton currently distributes version 8.8


Uninstall Other Anti-Virus Programs

It is important that you first uninstall any existing anti-virus software. In particular, many students each year try to install McAfee Anti-Virus without removing the Anti-Virus software that comes bundled with many computers. Symantec, Norton, and McAfee do not tolerate each other; if any two are installed, the computer will freeze on start-up, and will have to be dropped off.

NOTE: If you have a current, active, paid subscription to Norton or a personal version of McAfee, you are welcome to keep that subscription and install Carleton-provided anti-virus when that subscription ends or continue to use your personal paid service as long as you keep the subscription active.


To completely and cleanly remove Norton from your computer:

    1. Download the Norton Removal Tool (If the link is broken, search "Norton Removal Tool" and use the Symantec website link.)
      1. IGNORE the NORTON INSTRUCTIONS—There is a large list of Norton versions. This is to provide reinstall information, which is unnecessary.
      2. Go to Step 3: Download and run the Norton Removal Tool.
      3. Download the appropriate tool for your version of Windows and save it to the Desktop.
    2. Close the web browser and any other open programs.
    3. Double-click on the Norton Removal Tool on your desktop and run through the process as described.


Similarly, old versions of McAfee or free installations that come with a machine should be uninstalled. McAfee's removal instructions can be found here or by searching "McAfee Removal Tool".

Installation Files

You can download McAfee HERE (NetID required). You should download this version even if you already have anti-virus software installed, as it is specially configured for the Carleton network. After running the installation program, wait two minutes; this installer has a quirk that causes it to appear finished even when it is actually continuing to install. Then, reboot and check to make sure that the McAfee icon (a V in a shield) is among the icons in the lower-right corner of the screen. (You may have to click the "expand" arrow to see all icons.) If it is not there, try installing McAfee again.


To update McAfee, right-click on the shield icon and select Update now. If you are connected to either the Carleton network or the internet, the update should succeed. It is recommended that you update McAfee on a weekly basis. McAfee can also be set to update automatically.

If you wish to upgrade to a newer version of McAfee (from 8.5 to 8.8, for example), you should uninstall the old version first. Follow the instructions here.


To run a full system scan, right-click on the shield icon and select On-Demand Scan. When the options window pops up, click on the Scan Now button. This will take 15–45 minutes.

After the scan has completed, if any malware has been found, right-click on one of the items and choose Select All. Then right-click any of the items and choose Delete File. If any items could not be deleted, run the scan again in Safe Mode.
