Well it seems like Android is becoming a PC, as security firm Kaspersky detected a trojan going by the name of "Trojan-SMS.AndroidOS.FakePlayer.a”. This trojan is downloaded  as an Android app and according to  Kaspersky it is the first known Android targeted trojan.

The trojan poses as a media player app but when the app is installed, it starts sending SMS's to premium rate numbers without telling the user. As the creators of the trojan usually set up the numbers, they benefit from this scam. These types of trojans have been on mobile phones for years, but as far as I am aware, this is the first time it has been put on an Android device.

Kaspersky Lab is supposedly working on Android-specific antivirus software and plans to release it early next year. Even though there are antivirus apps already available in the Android Market, it was supposed to be unnecessary. But I guess it is only a matter of time before we see the 1990s war between the Mac and PC start all over again.
