Bad app: The TrustGo mobile-security app can scan the apps on your Android smart phone and let you know which ones might pose a security threat. It can also warn you about the potential dangers of apps before you download them.
Long gone are the days when the only computer viruses you had to worry about were those that would harm your desktop or laptop machine.
The rapid rise of smart phones and tablets—along with third-party apps that do everything from looking up restaurants to hailing cabs—presents all-new security threats, with the potential to give a handheld device a lot more than a case of e-sniffles. And even if an app isn’t doing anything that’s clearly malicious, like forwarding your usernames and passwords to hackers, it might be collecting more information than it needs.
With this in mind, a startup called TrustGo Mobile Security has released a free app called TrustGo Antivirus & Mobile Security, for phones running Google’s Android software (the most popular smart-phone operating system, with 51 percent of the market at the end of 2011, according to Gartner—and one that is increasingly the target of malware disseminators).
TrustGo scans the apps on a phone and compares them to thousands of apps that the company has already scanned across 200 different Android app marketplaces. The TrustGo app allows you to search for safe versions of an app—which may not always be hosted on the official Google Play Android app store. The TrustGo app also offers cloud-based data backup, a service to help you locate a lost or stolen phone, and safe Web browsing.
Mobile malware is increasingly common, and a number of services aim to counter the threat on Android devices. In February, Google itself introduced a service called Bouncer that automatically scans apps uploaded to Google Play in an effort to root out bad ones. Apple has always manually inspected submissions to its App Store—although that has not entirely prevented questionable app behavior.
There are also other mobile-security apps, such as Lookout and avast! Mobile Security. Yet TrustGo, which announced its app last week at the Demo technology conference in Santa Clara, California, believes its offering is more comprehensive, looking more closely at the permissions that apps require, and scanning apps so it can warn you of those that are potentially threatening before you download them.
