Ad lures victims to fake anti-virus app

Using on-device ads, a trojan has emerged targetting Android users which is known as "Android.Fakealert.4.origin". 

Windows users are well aware of this trick which has proved very effective over the years, but it's the first time a widespread attack like this has been reported on Android.

Unlike screening malware apps from the Google Play store, ads are a different beast altogether since almost all the free apps available show them as their primary revenue stream. In other words, the "delivery" mechanism itself is nearly impossible to remove.

Initially reported by Antivirus firm Dr Web, it is pointed out it is the advertisements that prompt users to scan their mobile devices for viruses and then lure them into downloading a fake anti-virus for Android - the ads themselves cannot carry the virus automatically into the handset.
