Well my daughter is none too happy with her Android. She switched from a Blackberry to a Motorola with Android. Some how she mus downloaded an app with a virus. The virus sent emails from her contacts list.
Does she sync her contact list with her laptop or computer? There have been trojans going around on computers that will spew out your contact lists...
Lots of the Apple Fans love to talk about viruses and malware on Android, but are amazingly silent when asked to provide proof. The fact is that there have been about as many problems in the Android Market as there have been in Apple's App Store - and that number for both is rather small.
