While some of these apps would look suspicious, others named things like "Quick Notes" or "Chess" seem innocent enough and you might not think twice about downloading them.

Tips for a Malware-Free Smartphone

Here are five quick tips to help keep your Android phone malware free:

1. Always research the publisher of the app. What other apps are they offering? Do any of them look a bit shady? If so, you should probably stay away.

2. Read online reviews. Android Market reviews may not always be truthful. Check around to see what reputable websites are saying about the app before you hit that download button.
