All computers connecting to the University network are required to have anti-virus software installed. While Windows 8 and 10 come with Windows Defender, other operating systems such as macOS and Linux will need to have a separate anti-virus installed.
You should only use one anti-virus software application on your computer. Using multiple anti-virus software will not increase security and can reduce your computer's performance significantly due to conflicts.
If you need any assistance installing or removing an anti-virus program, or if you are worried about malware on your computer, contact AskOtago.
