A few problems with all this.
Of the 43,000 bits of software attacking Android, how many of them are in the unregulated Chinese markets, over which Google has no control, and which the majority of non-Chinese users will never go to?
The assertion that iOS is practically invulnerable. Wasn't it last year that an app was approved by Apple and quietly sat slurping user data and sending it back to the developers server, and which was only closed down because the developer in question was a security-related bod, who was proving that iOS can be breached? Can anyone, hands on heart, say that this was truly a one-off and not one of the hundreds of thousands of apps in the AppStore do not do something very similar? Just because you don't have the tools to find a problem, doesn't mean it doesn't exist.
Finally... research by Kaspersky? Hmm, is that the same Kaspersky who charge £8.95 for phone security software and £11.95 for tablet security? Nothing to gain from scare-mongering, then?
Android isn't perfect, no software is, but let's not get carried away with such dodgy "research".
