Avoid Android Viruses on Your Droid Bionic
How can you tell which apps for the Droid Bionic are legitimate and which might be viruses or evil apps that do odd things to your phone? Well, you can’t. In fact, most people can’t, because most evil apps don’t advertise themselves as such.
The key to knowing whether an app is evil is to look at what it does. If a simple grocery-list app uses the phone’s text messaging service and the app doesn’t need to send text messages, it’s suspect.
In the history of the Android operating system, only a handful of malicious apps have been distributed, and most of them were found in Asia. Google routinely removes these apps from the Android Market, and a feature of the Android operating system even lets Google remove apps from your phone. So, you’re pretty safe.
Generally speaking, avoid hacker apps, and porn, and apps that use social engineering to make you do things on your phone that you wouldn’t otherwise do, such as text an overseas number to see racy pictures of politicians or celebrities.
Also, it's highly recommended that you abstain from obtaining apps from anything but the official Android Market. The Amazon Market is okay, but some other markets are basically distribution points for illegal or infected software. Avoid them.
