Uninstalling Anti-Virus Software

If you are installing a new anti-virus product, you will need to uninstall your old program first. For many products, you can simply uninstall the old program, but McAfee, Norton, and Sophos products may require special steps for proper removal.


McAfee can be removed with the McAfee Removal Tool. You may then proceed to install your new anti-virus software. 


Norton can be removed with the Norton Removal Tool. You may then proceed to install your new anti-virus software.


Sophos free version antivirus software installed on unmanaged personal student computers is not recommended. Students with Mac O/S are advised to uninstall Sophos and install recommended supported antivirus programs for Mac O/S listed above.
