According to Norton, the increasing malware problem on the Android OS is only going to get worse. They explain that Android has three key features that make it a target: it's an open platform, it's monetizable, and it is increasingly ubiquitous.
What's more, it's scarily easy to make an Android app into a Trojan horse. So it doesn't take a technical mastermind to make spyware, adware, and other malicious apps. And, while we're not blaming Google, the Android Market isn't exactly Fort Knox. Google will remove apps if they are reported, but they don't vet them in the same way that Apple does.
And we're really not blaming Google. The problem with fame and success, as any pro athlete will tell you, is that the world will come after you for all you've got. The real problem is that mobile malware is a young threat, so we haven't fully built solutions to combat it, as we have with traditional computers. Not to freak you out too much, but we imagine hackers are drooling over the potential for an NFC revolution, which would put more than our Facebook passwords at risk. Yay, fear-mongering!
