5 free Android security apps: Keep your smartphone safe

There's been much controversy over mobile OS security, especially where Android is concerned. With 47% of the smartphone market in Q4 of 2011, according to ABI Research, it's no wonder that Android is getting attention.

Its openness fuels adoption by smartphone manufacturers and wireless carriers, aids in mobile innovation, and helps bring more free apps. But some, like those who develop security apps, think its openness also makes it an easier target for malware writers and cybercriminals.

Depending on where you go, you'll find varying stats on the amount of Android malware we've seen thus far. This is complicated by the fact that most of the information available about malware comes from security vendors, who obviously have a pony in the anti-malware race.
