User Interface Use Avast Mobile Security even on your Android tablets, as the UI has been optimized for tablet display.
Performs on-demand scans of all installed apps and memory card content, as well as on-access scans of apps upon first execution. Options for scheduling scans, virus definition updates, uninstalling apps, deleting files, or reporting a false-positive to our virus lab.
Scans and displays (grid) access rights and intents of installed apps, identifying potential privacy risks, so you know how much info you are really providing to each app.

Part of the Avast WebRep™ cloud, the Avast Web Shield for Android scans each URL that loads and warns you if the browser loads a malware-infected URL.
Add a firewall to stop hackers. Disable an app's internet access when on Wi-Fi and 3G and roaming mobile networks. (Works only on rooted phones.)
After downloading Avast Anti-Theft, user can choose a custom name that disguises the app (e.g. call it "Pinocchio game") so that it is even harder for thieves to find and remove.
Once anti-theft is enabled, the app icon is hidden in the app tray, leaving no audio or other trace on the target phone – the app is 'invisible', making it difficult for thieves to detect or remove.
Establish a 'white list' of approved SIM cards that can be used in the phone without triggering a theft alert. You can also easily clear the trusted SIM cards list, to leave the one present in the phone as the only trusted one.
Anti-Theft only launches itself and runs when it needs to perform tasks. This preserves battery life and makes it very difficult for thieves to shut it down.
If stolen and a different (unauthorized) SIM card inserted, the phone can lock, activate siren, and send you notification (to remote device) of the phone's new number and geo-location.
Extremely difficult for thieves to remove (especially on rooted phones), Anti-Theft protects itself from uninstall by disguising its components with various self-preservation techniques. On rooted phones it is able to survive hard-resets and can even disable the phone's USB port.
A setup wizard guides the user through the installation process on rooted phones by either writing directly or by generating an update file. No command-line knowledge is necessary to install Anti-Theft rooted. Also supports upgrading the app.
Option to sound a loud siren, which returns always to maximum volume if thieves try to silence. This siren sound can also be customized (e.g. record own siren sound or select siren sound from file).
To protect your data, phone can be locked remotely and then cannot be accessed again without entering the password specified by the user.
Enables remote locking of the phone's App Manager and/or phone settings.
Remotely send a customized message to locked or non-locked phone display (e.g. with a reward for its return).
Remotely locate phone via GPS, Wi-Fi, or mobile network – for maximum accuracy. Can locate either once or continuously (GPS can be auto-enabled on all rooted phones or non-rooted phones from Android 1.6 to 2.2).
Remotely trigger a full, permanent wipe of all phone data (e.g. contacts, call log, SMS/MMS, browser history, apps, email accounts), including reliable, physical wipe of all memory cards from Android 2.2 on (limited functionality on older versions).
Remotely have the phone call you elsewhere with screen blackened, so that thieves cannot see it. This way you can listen to the phone's surroundings.
Remotely activate/deactivate option to forward or copy call data and/or SMS messages to another device. Call data goes to remote device, but not the call itself. SMS messages, however, are forwarded in their entirety ("CC" copies also to original device).
Remotely send a "Lost" command to trigger same actions as SIM card change (e.g. phone lock, siren, or USB lock). "Found" command deactivates "Lost" command.
Query the call log, contacts, and SMS messages remotely (with each forwarded as a separate SMS message, but able to be filtered).
Remotely trigger phone to send an SMS to another phone. That way, if you forget the phone somewhere, you can reply nonetheless to incoming calls or SMS messages.
Reboot the phone by SMS command, which will lock the phone by asking for the SIM's PIN code. (Works only on rooted phones.)
Phone is able to send low battery notification to a secondary device.
All of the Anti-Theft settings can be changed remotely.
We now offer a premium pack that includes more security features!
Your phone will execute specified actions, such as lock, siren, and send location, when it leaves a set perimeter.
Prevents access to and takes a picture of anybody attempting to unlock your device after three tries.

See the two ways you can control an Avast-secured phone.
All SMS commands must begin with your Avast PIN code.
For example, if your Avast PIN code is set to 2222, a lock command should look like this:
2222 LOCK
Sample: 2222 LOST Marks the phone as LOST. This command initiates the same actions as a SIM card change, depending on the settings.
Sample: 2222 FOUND Marks the phone as FOUND. This command disables the phone lock as well as the siren alarm.
Sample: 2222 LOCK Lock the mobile phone
Sample: 2222 UNLOCK Unlock the mobile phone
Sample: 2222 MESSAGE Give back my phone! Will display a message on the phone. Can be dismissed. Use LOCK and SET LOCKTEXT to display a sticky message
Sample: 2222 SIREN ON Turn siren on
Sample: 2222 SIREN OFF Turn siren off
Sample: 2222 LOCATE Locate the device
Sample: 2222 LOCATE 5 Track the device continuously
Sample: 2222 LOCATE STOP Stop continous tracking
Sample: 2222 CALL Sample: 2222 CALL +43660333555 If no phone number is given this command causes the phone to call you back. If you give the phone number the phone will call the given number
Sample: 2222 FORWARD SMS Sample: 2222 FORWARD SMS +43660333555 If no phone number is given, incoming SMS will silently be forwarded to the phone that sent the command. If a phone number is given, incoming SMS will be forwarded to the given phone number. This command overrides all previously issued SMS-forwarding-settings.
The forwarding can be cancelled by issuing the FORWARD SMS STOP command or by launching Avast Anti-Theft.
Sample: 2222 CC SMS Sample: 2222 CC SMS +43660333555 Same as FORWARD SMS, but will not delete the SMS after forwarding which means that the forwarded SMS will still be delivered to the target phone (CC means carbon copy). This command overrides all previously issued SMS-forwarding-settings.
The forwarding can be cancelled by issuing the CC SMS STOP command or by launching Avast Anti-Theft.
Sample: 2222 CC CALLS Sample: 2222 CC CALLS +43660222333 By issuing this command you can request SMS notifications about incoming calls. The notifications will be sent to the phone that issued the command if no other phone number is given. This command overrides all previously issued call-forwarding-settings.
We did not implement direct forwarding of the calls as this works differently in the networks around the world. Also it is not possible to hide the forwarding settings from the thieves eyes reliably.
The forwarding can be cancelled by issuing the CC CALLS STOP command or by launching Avast Anti-Theft.
Sample: 2222 CC ALL Sample: 2222 CC ALL +43660222333 Combines the CC SMS and the CC CALLS command. This command overrides all previously issued SMS- and call-forwarding- settings.
The forwarding can be cancelled by issuing the CC ALL STOP command or by launching Avast Anti-Theft.

Caution: By using this command you will completely disable the Avast! Anti-Theft system thus rendering the Anti-Theft protection useless.
Avast! Anti-Theft is able to launch any programs on the phone and pass data to the launched program.
SMS command: <Activity or service name, fully qualified> <arguments>
Samples:
2222 at.domain.package.Activity Test will start the activity OR service at.domain.package.Activity and pass Test as an parameter to it.
2222 at.domain.package.Activity This is my command line will start the activity OR service at.domain.package.Activity and pass This is my command line as an parameter to it.
The activity or service needs to be positioned on the root of the package (sub-packages are NOT supported).
Data transfer is done via Intent:
Intent i = new Intent();
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.putExtra("number", origNumber);
i.putExtra("cmd", data);
i.setComponent(cName);
This means you can then read (in your service or activity) the sender number in the String extra number and the command from the String extra cmd.
Anti-Theft always tries to start an Activity first, if none is found it tries to start a Service, if this fails it will reply with an error SMS.
More people around the world trust Avast for their security than any other company. That means better security for all of us. The reason is simple: We see and react to more data from more users, so we can make your protection better.
