Attached is a file VoiceATT0685424.zip which in turn contains a malicious executable VoiceMessageTT.exe with an icon to make it look like an audio file.

VirusTotal. Automated analysis    shows a connection to a domain called adamdevarney.com on 126.96.36.199 (Westhost, US) which has been seen twice before. This means that there are potentially hundreds of compromised domains on the same server, blocking traffic to the IP address will be the most effective way of giving yourself some protection.
