1. Installing and Updating Sophos
These instructions are primarily for people who want to install Sophos Anti-Virus onto their personal laptop and/or desktop. Please check with your local IT Support Staff about antivirus protection for college and departmental systems as local arrangements often apply, and installing the version intended for personal systems may cause problems.
This guide outlines the steps required to install the Sophos anti-virus software on Apple Mac computers. Although currently relatively little malware targets OS X systems, it is in on the increase. Some malware can compromise the security of your system, and may capture information you use to connect to other systems such as over the Internet, so we do recommend that Mac users install anti-malware software such as Sophos as a precaution.
For comprehensive instructions on installing and configuring the Sophos software refer to the appropriate Sophos installation guide from the Sophos Documentation pages. The following is a brief outline of the first-time installation of Sophos on an Apple Mac.
The file you download from our website (which will be named something like
sophos8osx2013.dmg) is a special type of file called a disk
image. Depending on the method you use to download the file, it may automatically
mount a disk image called
Sophos 8.x for OS X 10.4+ or similar on
your Mac desktop and open it automatically.
However it is likely that the disk image won't mount automatically, in which case you
will need to select it from the list of downloads, or find it (most likely in your
Downloads) folder and double-click on it to mount the image.
Once you can see the installer, double-click on it to start the Sophos installation. The installer windows that you see may look a little different to those shown below. If so, youd generally just need to accept the default settings to install Sophos.
Close to close the installation window. If Sophos wasn't
installed before you should now see a shield in the menu bar (top right of the screen).
The shield may initially be grey but after just a few moments should turn black to
indicate that Sophos is now protecting your computer.
The version of Sophos you have installed now needs to be updated so that it can detect
recent malware. To do this make sure that you are connected to the Internet and then
click on the shield to bring up the menu shown and select
Sophos Anti-Virus uses a username and password to automatically download updates. These credentials are valid for around 14 months and expire around the start of November each year. Once they have expired, Sophos will no longer be updated, and your computer will be more vulnerable to new viruses and other malware etc.
This normally only applies to Sophos installed onto personal laptops and desktops. On college or departmental systems, Sophos (or other antivirus software) is often managed by your local IT Support staff and you should check with them before making any changes.
To make sure that you keep your computer(s) up to date, you will need to download and install a new Sophos package in October each year. Please see the FAQ for more details on how to check when your installation(s) of Sophos will stop updating.
So long as the updating credentials are current, Sophos Anti-Virus is configured to automatically download and install updates to keep your defences against viruses, trojans and worms as up-to-date as possible. On networked computers, this occurs once an hour.
You can also update Sophos manually at any time by clicking on the
on the menu bar and choosing
[Update Now]. You will see a window showing the
progress of the update. The progress window is not displayed when Sophos updates
Your computer does need to be connected to the Internet in order to download updates so if you see this icon when you are not connected this is normal and nothing to be concerned about. When you reconnect to the Internet it may take up to an hour before Sophos tries to update again and the shield returns to normal.
