Help Article - email links
One method commonly used to infect a computer with a virus is through a link within an email. One example is shown here in an article by the ABC. An attacker can send an email disguised as a banking email or some other legitimate looking sender. These attacks can be sophisticated (social engineering attacks) and can do as much as render a computer completely useless.
Best practices for email links are to not to click on any email links, although for many people this isn’t practical. One phrase used by IT security experts is don’t click on it if you didn’t go looking for it - If you asked to be emailed, then it’s much more likely to be legitimate. Knowing about this method of attack in the first place is a good start in being aware of possible malicious emails.
Note that a known email sender isn’t a sign of legitimacy, they could possibly have had their email account compromised.
Webmail products such as Gmail also serve to help protect with inbuilt spam filtering.
Avoiding webpage links that navigate to malicious websites can be helped with good browsing practices.
