The Bad It only scans apps; it needs a deep scan feature to check media files and more.
The Bottom Line TrustGo is one of the most robust Android security apps we've seen, and it's completely free.
TrustGo Antivirus & Mobile Security
TrustGo's main dashboard is sleek, especially considering the number of features waiting behind each of its buttons and tabs. The Security tab gives you access to the program's Security Scanner, System Manager, Privacy Guard, and Data Backup features. There are also sliders to toggle Secure Web Browsing and Device Protection functions. Meanwhile, the Apps Manager tab gives you a convenient hub to see all of your installed apps and the memory they take up. You can also uninstall or update them right from this screen.
As for security features, TrustGo offers many, the most important of which is probably the Security Scanner. On an as-needed basis, you can fire up the Security Scanner to sweep your locally installed apps as well as those saved on your SD card for any potential security risks. Additionally, you can set this to run on a weekly or monthly basis, as well as any time you install a new app. While this feature does work well, one thing it's missing is a deep scan that sweeps system files and even media files. Such a feature would eliminate a lot of other potential threats. Meanwhile, there is a Secure Web Browsing feature, which notifies you if you navigate to a site that is known to be malicious. It only works on the stock Android browser and Dolphin browser for now, but it helps.
The System Manager is more of a quick overview tool. It keeps track of your data usage, battery life, and memory usage. If you have a limited data plan, you can enter your limit, and have TrustGo notify you when you reach 90 percent of it. This is a pretty convenient tool, as you can set it to automatically refresh its readings at the end of your billing cycle, so you always know when you need to reduce your usage.
