Security Features

Why choose avast! Free Mobile Security?

A standalone yet tightly integrated component of the avast! Mobile Security environment, avast! Anti-Theft is the slyest component on the market – because your security app should not alert potential thieves about its presence. You'll be able to remotely control your 'lost' phone by SMS at any time, with no signals indicated on the phone itself. Formerly known as Theft Aware, the Anti-Theft portion of avast! Free Mobile Security has been recommended by leading industry experts that include T-Mobile, N-TV, AndroidPIT, and Android Police.

avast! Mobile Security

Antivirus

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.

Privacy Report

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.

Web Shield

avast! Anti-Theft

App Disguiser

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.

Stealth Mode

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.

Self-Protection

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.

Battery Save

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.

SIM-Card-Change Notification

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 .

Trusted SIM Cards List

Establish a '' 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.

Remote Settings Change

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.

Remote Features

Remote Siren

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).

Lock Phone Settings Access

Remote Calling

Remote Forwarding

Remote "Lost" Notification

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.

Commands

SMS commands overview

Avast! Anti-Theft can be remotely controlled by using simple SMS commands. For this, the Anti-Theft protection needs to be enabled within the Anti-Theft basic settings.

If within the remote control settings, you restricted SMS commands to friends, SMS commands are only accepted if they are being sent from phone numbers that match one of the friend phone numbers you specified. All SMS commands s ent from other numbers will be ignored.

SMS command structure

All SMS commands must begin with your avast! password. For example, if your avast! password is set to 2222, a lock command should look like this:
2222 LOCK

LOST
Sample: 2222 LOST
Marks the phone as LOST. This command initiates the same actions as a SIM card change, depending on the protection behavior settings.

FOUND
Sample: 2222 FOUND
Marks the phone as FOUND. This command disables the phone lock as well as the siren alarm.

LOCK
Sample: 2222 LOCK
Lock the mobile phone

UNLOCK
Sample: 2222 UNLOCK
Unlock the mobile phone

Turn siren on

SIREN OFF

CALL [phone number]
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

FORWARD SMS [phone 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.

CC SMS [phone number]
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.

CC CALLS [phone number]
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.

CC ALL [phone number]
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.

Implement own remote commands

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.
