People are being warned to watch out for a scam doing the rounds on WhatsApp. 

It's an email with a subject line which reads 'Missed Voicemail'.

The content of the mail reads 'New Voice Message'. 

There's also a 'Play' button in the email and if you click on that it will download this trojan virus.

People are being advised to log in to their WhatsApp account the normal way and check for any messages there. 

If people hit the 'Play' link it could expose their computer to ransomware which ends up locking your files and demands a ransom of several hundred euros.
