Learn about Cox Anti-Virus Protection.




Need to learn more about the Cox network-based anti-virus service? It's designed to further combat the spread of viruses through email. This service is free to all Cox High-speed Internet customers, and is automatically activated. Anti-Virus Protection will scan all inbound and outbound email messages, and no customer configuration is necessary.

Anti-Virus Protection scans all incoming and outgoing email and is compatible with any email software, as well as both Windows and Mac operating systems. 

The following frequently-asked questions will assist in answering some of the most common questions.

How does anti-virus protection work?

  • All messages sent to Cox customer email accounts on the cox.net domain, meaning email addresses ending in @cox.net, are checked for viruses before being delivered to the customer inbox or WebMail.
  • If a known virus is detected within an email, the service removes the infected attachment. The rest of the message is then delivered along with a notification stating the infected attachment was removed.
  • If an infected attachment is detected but cannot be removed, the service deletes the entire email message and sends a notification explaining the email was removed. The email notification message is sent from the Cox Virus Monitor.
  • If an outgoing email message contains a virus-infected attachment, the message will not be delivered. This will help prevent spreading the virus to friends and family. The customer is notified that the email message was not sent to its destination.

Cox does not read customer email messages. This automated solution only detects known viruses.

Although the new Cox Anti-Virus Protection provides protection against viruses transmitted by email, we still recommend the use of anti-virus software on customer computers. This will protect them from viruses transmitted through Internet sites, Internet downloads, discs, portable drives, and other mechanisms through which viruses spread. 

Note: Anti-Virus Protection does not prevent downloading of virus-infected files, nor will it remove viruses already present on a customer computer.


How do I control viruses?

Visit the Anti-Virus Resource Center. This support page provides additional, detailed information on Anti-Virus Protection and tips for minimizing viruses on customer computers.

Viruses are not only designed to infect a computer, but to spread to other computers. Some viruses read customer email address books and email the virus to everyone in the address book. Other viruses attach to every outgoing email. To help avoid receiving a virus, note the following:

  • Do not open any email attachment if the sender is unknown, or if the message text or attachment name seems odd.
  • Scan all attachments and files received using an anti-virus program which has been updated with current virus definitions.
  • Do not download from unfamiliar sites or sites which may be questionable.

Customers should consider Cox Anti-Virus Protection a complimentary service to their existing PC-based anti-virus solution.

How does Cox combat viruses?

Cox has taken steps to address the issue of spam and how to prevent it through the following measures:

  • Protecting privacy - Cox does not sell customer email addresses. We value our customers, and their privacy is important to us.
  • Blocking known viruses - The Atlanta Abuse Team monitors the network daily for any signs of viruses. When a new virus is detected, the Abuse Team immediately looks at implementing filters on our servers to prevent the spread of the virus.
  • Monitoring the network - If a virus is detected within the high-speed Internet network, the Atlanta Abuse Team scans the network for customers that are possibly infected. If an infected customer is identified, the Abuse Team temporarily suspends the customer to prevent further spread of the virus, and to protect the customer from becoming a victim of the virus creator.
  • Blocking commonly used ports - Filtering port 25 drastically reduces the number of infected emails from customer computers. Cox took this action to ensure that a few bulk emailers, or virus disseminators, did not result in the entire Cox.net domain being blacklisted by other Internet Service Providers (ISP).

Note: The Cox Email Anti-virus Protection is not a replacement for the customer's current anti-virus solution, but is an additional layer of protection.

How do I react if I receive a virus?

Do as little as possible with the computer, because every action could spread the virus. Immediately update the anti-virus software and run a full virus scan on the computer. Properly updated anti-virus software should remove the infected files.

If you receive an infected email, send it to Cox for review. We will work with our partners to ensure that this type of virus is detected in the future.

To submit an email, forward the email virus to virusreport@cox.net.

Note: All suspect emails must be forwarded as an attachment.

How am I notified of an infected email?

If you send or receive email that contains an attachment with a detected virus, you will receive a specific message from Anti-Virus Protection similar to the sample:

(Customer receives an email with an infected attachment):

From: Cox Communications

To: janedoe@cox.net
Subject Line: Email Virus Notification

An email was sent to you that we have identified as containing a virus. Below find the details of the infected message:
