Within the email, there is an infected MS Office file, or a link which opens the exploit landing page.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Avoiding it looks fairly uncomplicated, but still requires a lot of focus. Malware can hide in different spots, and it is far better to stop it even before it goes into your system than to trust in an anti-malware program.
