About Malware and Viruses


Cox Communications is dedicated to protecting the internet experience of our customers. When Cox detects that one or more of your devices or computers is infected with malicious software, also known as malware or viruses, we send you an email to your preferred email address as well as any Cox Email addresses on your account.

Handling Viruses and Malware

Cox recommends several actions to help you resolve virus or malware infections.

  • Check to make sure you have installed Cox Security Suite Plus powered by McAfee® to help keep your devices protected from online threats. Cox Security Suite Plus is offered at no additional charge to Cox Internet customers. To download the software for free, visit www.cox.com/securitysuite to sign in to My Account with your primary User ID and Password.
  • Be sure to scan for viruses on all devices connected to your Cox Internet service. The computer or device that received the email notification may not be the infected device or computer.

Because no single security software is 100 percent effective, Cox recommends that you run additional software in addition to Cox Security Suite Plus. There are many anti-virus programs available, both free and for purchase. The following are a few examples of additional software that can remove infections.

  • Microsoft Safety Scanner - Microsoft Safety Scanner is a scan tool designed to find and remove malware from Windows computers.
  • Norton Power Eraser - This tool is useful if your computer has become a victim of crimeware that regular virus scans cannot detect.

While this software may be helpful to you, Cox provides support only for Cox Security Suite Plus. Contact the software manufacturer for assistance.

If you need some extra help, Cox offers premium technical support. Visit www.cox.com/completecare to reach Cox Complete Care or call 877-COX-ASST (269-2778).
