  • Proactive Bot Notification: As a new feature of the Constant Guard service, we may email a "Service Notice" to your Comcast email address if we believe one or more of your computers may be infected with a type of virus called a Bot. A Bot is a malicious form of software that could use your computer to send spam, host a phishing site, or steal your identity by monitoring your keystrokes.

A Bot is a malicious form of software that could use your computer to send spam, host a phishing site, or steal your identity by monitoring your keystrokes.

Look for the following symptoms:

• Numerous undelivered e-mail notifications in your inbox to unknown e-mail addresses. Bots will frequently use e-mail accounts to send out spam. Spam to unknown e-mail addresses will result in a "failure to deliver" notification in your inbox. Please click here to sign into your comcast e-mail.
  
• Suspicious e-mail account activity. Bots create multiple e-mail addresses in your e-mail account. If you notice additional e-mail addresses in your account that you did not create you may have an infected computer. Please click here to sign into the My Account section of your comcast.net account.
  
• Multiple toolbars on your Internet Web browser. Bots will frequently install various toolbars to help collect search information from your Web browser.
  
• Unusual error messages. Error messages that suggest applications cannot run or drives cannot be accessed can be indications of a bot infection.

We identify infected computers in several ways. First, we get data from reputable Internet research groups that specialize in bot identification. The data we get includes a list of Internet Protocol (IP) addresses that are infected and those that belong to bot command and control channels. Second, we look for malicious behavior exhibited by bots such as spam, distributed denial of service attacks and repeated connections requests to known command and control channels. We then aggregate this data to confirm whether one or more of your computers has been infected.

A Comcast "Service Notice" can be issued in the following ways:

• An in-browser web notification that appears as a transparent message during browsing and an e-mail to your primary comcast.net e-mail address.
• An email notification to your primary comcast.net email address.

Below is a sample of the email sent to your primary comcast.net email account.
