VIRUS SECURITY ALERT!

Security Alert.

Yesterday, a client dropped off his PC. He explained that all he did was open an official looking email in reference to suspicious activity on his Internet usage. So he opened it.
After rebooting, a message popped up. The accompanying pictures explain the rest. Please, do not open anything that looks intriguing or that you have not inquired. My client's PC is rendered useless. 
Be careful and stay safe.
