HSU provides you with a free license for Sophos Anti-Virus to help protect your computer against viruses and other malware. It's installed automatically on all HSU-owned computers, and is free to download onto personally-owned computers by anyone with a valid HSU User Name and Password. A number of other antivirus programs are also acceptable; up-to-date virus protection is a precondition for connecting to any HSU network.

In the pre-web days, you'd know that your computer was infected because threatening messages appeared on your screen, or applications stopped working. Today's malware aims to get onto your machine and steal valuable information, not show off programming tricks. They wrap themselves in a cloak of pseudo-legitimacy, appearing as a message or request for information from an official source, such as your bank, eBay, even the HSU support team.

If you receive a message asking for confidential information such as your social security number, HSU or online banking passwords, or with an attachment you didn't request, contact the sender by phone to check the legitimacy of the request. Do not click on any links or open any attachments without checking first.

Who's it for?

System Configuration

Sophos Anti-Virus runs on Windows and Macintosh computers. You'll need one of the following operating systems to install it:

  • Windows 2000 Pro SP3+, XP Home/Pro, Vista, 7
  • Mac OS X (10.4/10.5/10.6)

Additional Information

Because certain types of file are commonly used to transmit malware, those types of file may not be sent over the HSU email system as an attachment to a message. Follow these instructions to transfer files safely. Emails with unsafe attachment types will be blocked and the sender will see an error message.

You must have Sophos or another HSU-approved antivirus program installed in order to connect to the HSU wireless and ResNet networks.

More information on the Sophos Anti-Virus software itself can be found on the Sophos website.
