To lower the risk of virus infections via email, which two actions should be taken?

Running antivirus software on the client is a crucial step in lowering the risk of virus infections via email. Antivirus software actively scans incoming emails and attachments for known malware and viruses, providing a layer of protection that can identify and potentially remove harmful content before it can infect the system. This software stays updated with the latest virus definitions, ensuring that it can combat new threats effectively. By having this software installed and regularly updated, users significantly enhance their email security.

Additionally, opening only attachments received from trusted sources is equally important. This practice minimizes the risk of inadvertently downloading malware, as emails from unknown or untrusted sources can often carry malicious attachments designed to compromise security. By being cautious and verifying the legitimacy of the sender before opening any attachments, users further protect themselves from potential virus infections.

Together, these actions create a robust defense against email-based threats, making it less likely for viruses to infiltrate devices through email communications.
