Which action is a recommended strategy to prevent malware?

• A. Create strong passwords
• B. Do not open emails from anyone you don't know
• C. Make sure your electronic devices are up to date
• D. Do not click on unknown links

Answer: (A)

Strong passwords act as a frontline defense because malware and cybercriminals often gain access through stolen or guessed login credentials. If an attacker can log into an account with weak or reused passwords, they may install malicious software, access personal data, or spread malware from that trusted foothold. A password that is long, complex, and unique for each site makes it much harder for automated attacks or credential theft to succeed, limiting the attacker’s ability to reach sensitive systems. While keeping devices updated and avoiding unknown links are important overall safety measures, this action most directly reduces the risk of malware by preventing unauthorized access that could enable its installation or spread.
