Cox Customer Safety email

I received an email titled Compromised Computer Notification from Cox Communications.  Wondering if this is valid or a fake. Any ideas??? Seems strange   

Cox has identified that one or more computers/ devices behind your cable modem may be infected with the FakeSecSen or "Spy Sheriff" Virus. A device behind your cable modem appears to have connected to a command and control server affiliated with this malware.

Viruses can take control of your PC and gather your personal information such as passwords and credit card numbers, putting your data at risk

The following FREE security tools could help you detect and remove infections from your systems:
