Subject: Constant Guard Security Notice
Constant Guard has identified that one or more of your computers may be infected by a computer virus known as a bot.
A bot is a form of virus that is used to gain control over a computer, typically without the owner's knowledge. Online criminals can use bots to collect personal and private data such as Social Security numbers, bank account information, and/or credit card numbers. This can also lead to identify theft.
We recommend that you take a few minutes to visit the Constant Guard Center for instructions to assist you in removing the virus from your computer. To help stay protected, we strongly advise you to perform regular Operating System and anti-virus software updates.
Comcast also makes extensive information available about the latest security alerts on the Comcast.net website. To view this information we urge customers to visit the www.comcast.net/security.
Thank you for choosing Comcast!
