I couldn,t tell you why, but not something I have come across with the iPhone.

"Smartphones running Google's Android software have been hijacked by an illegal botnet, according to a Microsoft researcher.

Botnets are large illegal networks of infected machines - usually desktop or laptop computers - typically used to send out masses of spam email.

Researcher Terry Zink said there was evidence of spam being sent from Yahoo mail servers by Android devices.

Microsoft's own platform, Windows Phone, is a key competitor to Android.

The Google platform has suffered from several high-profile issues with malware affected apps in recent months.

The official store - Google Play - has had issues with fake apps, often pirated free versions of popular paid products like Angry Birds Space or Fruit Ninja.

This latest discovery has been seen as a change of direction for attackers.

"We've all heard the rumours," Mr Zink wrote in a blog post.

"But this is the first time I have seen it - a spammer has control of a botnet that lives on Android devices.

"These devices login to the user's Yahoo Mail account and send spam."
