Sophos Anti-Virus - Uninstall & Removal Instructions

At the end of May 2013, LIS will no longer provide or support Sophos Anti-Virus on personally owned computers.

This means that faculty, staff, and students will have to remove Sophos and acquire their own anti-virus software to protect their computers. A list of alternative options, including free anti-virus products, is available at the Anti-Virus Software page. Technology Help Desk staff are available to assist with the transition away from Sophos.

This change is being made for a variety of technical reasons and to ease some of the troubles involved in updating Norse Keys, which could lead to a computer being vulnerable to viruses.

Sophos will remain on Luther owned workstations.
