A warning message in the user’s browser stating the site’s certificate cannot be verified indicates that the site may be insecure, fraudulent, or malicious. This could be a sign of a phishing attempt, where the sender of the email tries to trick the user into clicking a link that leads to a fake website that mimics a legitimate one, in order to steal the user’s personal or financial information. The most appropriate action for a technician to take in this situation is to close the browser window and report the email to IT security, who can investigate the source and content of the email, and take the necessary steps to protect the user and the network from potential harm. Clicking proceed could expose the user to malware, identity theft, or data breach. Reporting the employee to the human resources department for violating company policy is unnecessary and harsh, as the user may not have been aware of the phishing attempt or the company policy. Restoring the computer from the last known backup is premature and ineffective, as the user may not have been infected by anything, and the backup may not remove the email or the link from the user’s inbox
