Defensive users think critically about the information they can access, to reduce their chances of downloading and spreading malicious software. Strategies include scanning email [[email attachments]] prior to opening them and manually filtering suspicious emails from inboxes.

Skepticism can also be applied to the websites visited by users. As with emails, users can be lead to false advertisements. Also, malicious software can unknowingly be downloaded and infect a computer, just by visiting a certain website.
