Complete all available updates for your computers, operating systems and browsers. Use antivirus programs to detect malicious software and prevent damage to files or devices. Never open emails or attachments from someone you don’t know or aren’t expecting, and be especially cautious of forwarded attachments. Do not click on online advertisements, as these can be scams to gather your personal information. Recognize signs of email scams, such as a generic greeting, a notice that your account is on hold due to a billing problem or an invitation to click a link to update information. Legitimate companies will not email or text a link requesting payment information or demand specific payment forms, such as gift cards.
