How can I protect my computer from viruses?

• Install anti-virus software and keep it up to date.
• Configure the anti-virus software for increased protection.
  There are links on the Virus protection page to guides that explain how to obtain, install and configure VirusScan anti-virus software. For information on how to protect your Mac see Sophos Anti-Virus software for the Mac.
• Back up your data on a regular basis
• Don't open or preview mail from unknown sources.
• Be very wary of any email attachments you receive. If you do not know who it is from, delete the message. Otherwise first save the attachment to disk before opening it.
• Don't download files from sources you don't trust.
• Keep your operating system up to date.
