Beware the malware lurking on Android Market...
Android's openness is also its weakness when it comes to malware. But some simple user education can reduce the risk, says KPMG security expert Malcolm Marshall.
The massive adoption of smartphones and tablets in 2011 was accentuated by the Christmas period sales figures. According to mobile analytics firm Flurry, close to seven million new smartphones were activated globally on Christmas Day.

Such a large market is immensely attractive to those looking to profit illegally from the boom. Using apps to deliver malicious payloads is not new but there has been a marked increase in the number of bad apps detected over the past two years.
The targeting of Android-based devices during 2011 experienced an exponential growth. Some forecasts for 2012 predict an increase in bad applications of a staggering 6,000 per cent. These include a mix of malicious applications as well as apps that breach users' privacy.
In December a number of media outlets reported that several fake versions of popular applications were removed from Android Market. A similar attack was detected in the first week of January, again affecting Android Market.
