New Antivirus client for Macintosh systems

You are receiving this email as our records indicate that you have installed at least one copy of Sophos Antivirus on a University owned Macintosh computer.  Our contract with Sophos expires on August 31, 2010 so you must remove the software from your machine(s) prior to that date.  Our contract with Sophos also covered a copy of the software for one home Macintosh system so you will need to remove any copies installed on your home systems as well.

UWO has negotiated a new contract with Trend Micro Inc. for antivirus software.   The use of Trend Micro software on Western faculty/departmental computer systems is purchased and maintained by Western’s central administration. For information regarding costing for use on Affiliate or Ancillary unit computers, please refer to the ITS Services document @  (this document will be updated on or about July 2nd).

Unlike our previous agreement with Sophos, this new agreement does not cover home computers.  Trend Micro’s  Officescan for the Mac is available from the University Computer store at a cost of $20.00 (taxes incl) for your home computers.

Uninstall Procedure for Sophos Antivirus.

If you still have the disk image you used to install the application on your Macintosh system then you should have a copy of the uninstaller. If you no longer have a copy of the disk image you can go to  and download the disk image again.

You will need to ensure that you run the correct uninstaller for the version of Sophos that you have installed. To find out the version you are currently running you will need to click on the Sophos icon located at the top right of your monitor near the date and time and choose “About Sophos Antivirus” from the drop-down menu. If you are running version 4.x then you will need to run the “Double-click-to-Remove-older-4.9-Sophos-Anti-Virus.pkg” to uninstall the software.

If you are running version 7.x then you will need to run the “Double-click-to-Remove-Sophos-Anti-Virus.pkg” to uninstall the software.

Once you have removed the software you will need to reboot your system before installing the new Trend Micro Security software.

Installation procedure for Trend Micro Security for the Mac

Use your favorite web browser to go to and download the file entitled “tmsminstall.mpkg”. Locate and double-click on the file to start the installation process. Follow the prompts and upon completion the program will update itself to the latest pattern files.
