This review is for those of you having an android device and don’t get concerned about the data and security of your device. For many of us myth exists that android does not get attacked by viruses and malwares.  This has been proven wrong by many surveys and reports by antivirus companies. As  a matter of fact the number of malware and virus attacks on android has increased much more than any other mobile OS. Now increase with people holding droid in their hands have provided ample opportunity to hackers and phishers to steal data from the device. Android being open source is a root cause to this.  Almost all of us agree that the rate at which mobile devices are becoming our substitutes to surf net and do online shopping which was done some years ago by laptops, desktops, our mobile devices are more vulnerable to security threats.  Be it an identity theft, malware attack, phishing or any other security breach, it becomes our responsibility to keep our devices safe. A lot of antivirus, anti-malware, antitheft software are available in the market, but at paid expense.  You are having an android device and don’t want to pay 20-30 $ each year, then have a look at some completely free apps which are one stop solution to all your fears.

TRUST GO antivirus and Mobile security

TRUST GO antivirus and Mobile security

Trust go has been one of the most active companies in providing you completely free app, not even a single buck to pay for using its advanced features with over 1 million downloads and 4.5 average rating , no lite, no trial , completely free.

You can understand this by an example about the news that exynos processors of Samsung are vulnerable to hacking where an app can root the device without your permission and can do whatever it wants with your device. Trustgo has released a patch ( i.e. an app that will prevent this) and is available at no cost at their home page http://www.trustgo.com/en/

App features
The UI of app is pretty simple and easy to use

  1. Security scanner: It scans the apps installed and has option to scan sd card also. Needs data connection because it doesn’t store any virus definition in app, all it does it online so don’t need to update any virus definition as simple as that.
  2.  System manager: You can set data limit , have look on active apps, memory usages, battery usage by apps and a lot more
  3.  Privacy guard: It notifies you which app is using your contacts, which can access your identity, messages etc.
  4.  Data backup: You can backup all your contacts, messages and call history on cloud which can be retrieved back when needed, personally the most useful for me
  5. App manager: It shows a list of new apps in Google play
  6. Settings : You can customize the real-time protection, SD card scan , update and data usage schedule , simple to use
  7. Antitheft: Needs your gps to be enabled. Sorry no sms lock feature, biggest disadvantage.

It’s too simple to use

  1. Find my phone- Just click the link and it will show you the map with your droid location. Do Note that gps option in settings should be on and app should be running in background and most important data connection must be on otherwise app shows you phone in offline mode. You can lock, wipe, alarm and show some text on display screen.
  2.  Backup: Remotely get contacts, messages and call history out of your device.
  3. Control panel: You can change password or device name add or remove it etc.

Pros: don’t use much ram just 5-10 mb in background, easy to use easy setup, backup feature
Cons: doesn’t have sms lock feature so if no data connection or gps off, you have lost your device.
