Trojans, Android devices and WiFi networks

Asked By Bruce P Sharp 5 points N/A Posted on - 09/25/2014

My Android tablet caught a Trojan, so the first thing I did was resetting its factory settings, in the hope that it would be deleted. How can I know for sure that the Trojan is gone? Now I am concerned about my other devices attached to the same WiFi network as the Android tablet. Are they at risk? Do I need to change the password and/or other things?

Trojans, Android devices and WiFi networks

Hello Bruce

First, if you have already detected the Trojan, then first search for its characteristics on the web.

Secondly scan all your  devices with an updated Anti virus solution. 

Next change all your passwords to all the sites you would have browsed from your tab.

From now on keep your Anti Virus and Operating System up to date.

Hopefully all should be well after this.

Yes, doing a factory reset on your handset will remove all traces of Trojan infections. But before doing a factory reset, remember to backup your important data because resetting the phone to factory default will erase all saved data from the device. Updating your phone’s firmware also helps in preventing a virus infection.

Back in 2013, a “Master Key” vulnerability was discovered by experts at Bluebox Security in the Android operating system that existed since Android 1.6. The uncovered security flaw lets a hacker convert an apparently legit application into a Trojan. After this vulnerability was discovered, Google patched it in a February 2013 update.

To check for updates on your Android device, navigate to System Settings, About Phone, and then System Updates. Installing malware apps or mobile security applications will also help prevent a Trojan from entering your device. You can find free mobile security apps on Google Play. Download a mobile security app so your device will have a protection.
