How to wipe the data from my lost smartphone

howto2_enQuestion of the week: My phone was lost and there is no way to recover it. Thank goodness I had the data backed up. How do I use avast! Mobile Security to wipe all my information off of it?

We’re sorry that you lost your phone. You are not alone. Over one hundred smartphones are lost or stolen every minute of every day, but unfortunately 34% of smartphone owners haven’t protected their phone like you did. Congratulations on taking the initiative to back-up your data! We found out that half of smartphone owners don’t back up their data, even though they are concerned about losing it. (This seems to be theme – same thing happens with changing passwords.)

Many smartphone owners do not have anti-theft installed

Half of smartphone owners don't backup their data

If there’s no way to recover the device, then you are wise to use avast! Mobile Security to remotely wipe your phone of all your personal data.

Thorough wipe

Avast! Mobile Security and Anti-Theft has remote features that allow you to take certain actions. Wiping the phone can be carried out by SMS command. This is useful in your case when you do not expect to get your phone back and you do not want a thief to access your personal data. Read about how you can set up remote control on your Android phone.

Thorough wipe allows avast! to permanently and irreversibly delete the content of any SD card when wiping the phone. Wiping smartphones using up to Android 2.1 is somewhat restricted as a factory reset of the phone is not possible. However, avast! will try to delete as much as possible, for example contacts, call logs, SMS/MMS, browser history and SD card content, but not emails or apps.

From Android 2.2 onwards, a full factory reset is possible so you have full wipe capabilities. However, please be aware that this will also delete avast! Anti-Theft, unless it was installed as a rooted application.

The thorough wipe will take up to ten minutes, and will physically and irrecoverably delete the actual contents of your SD card. It is your choice whether to select the maximum level of security by using the thorough wipe option.

Protect your data with avast! Anti-Theft

To do a full wipe, avast! Anti-Theft needs to be configured in the advanced settings as a device administrator, otherwise applications, emails etc. will not be deleted. Download and install avast! Mobile Security and Anti-Theft from the Google Play store.

Don’t forget to backup your data with avast! Mobile Backup. It saves your contacts, call logs, SMS history, photos, and other irreplaceable data to your AVAST Account (and, optionally, Google Drive) to ensure that your priceless data is never lost. Download avast! Mobile Backup for free from Google Play.

All SMS commands, along with a short description how everything works is explained in our manual (PDF). It’s short and easy to understand.

How to set up your smartphone for remote control

howto2_enQuestion of the week: I just installed avast! Anti-Theft on my new Samsung Galaxy S5. If it gets lost or stolen, I know I can use remote control somehow. What do I do to set that up?

Congratulations on your cool new phone! It would be awful to lose that! Now that you have the free avast! Anti-Theft installed, you need to set it up so you can use the remote control features to control your phone via the avast! Portal or by SMS commands using a friend’s phone.

Communicate via your online account

First, make sure you set up an account on our online portal at my.avast.com to communicate with the anti-theft installation. Once you set it up, you get an overview of all your devices protected by avast! security products and you can pair the devices with the online account.

To pair your smartphone to the account open avast! Mobile Security, open the Settings section and tap on the avast! Account. The wizard will lead you through the registration or pairing process.

Once that’s done, you can remotely control your mobile devices on which avast! Mobile Security and Anti-Theft is installed.

Control your smartphone with avast! Anti-TheftCommunicate via a friend’s phone

Another way to communicate with your phone is by SMS commands using a friend’s phone. To do that you need to specify one or two phone numbers of friends or family members who will receive the Anti-Theft notifications from your phone.

To add a friend’s phone number, open avast! Anti-Theft and click on Friends. You can add one or two phone numbers here. Before you leave the screen, you have one more decision to make: Go to the bottom and check the box Only allow friend commands to allow SMS commands only from the specified friend’s numbers, or, if left unchecked, SMS commands will be accepted from any number. If you change your mind later, you can remove that restriction, by de-selecting the option.

SMS commands to remotely control your phone

Using the SMS commands, you can silently retrieve details of calls made and received, copies of incoming or outgoing SMS messages, you can remotely lock your phone, sound a siren or even remotely wipe your phone of all your personal data if you do not expect to recover it. You can also receive continuous GPS updates so that you can track your phone’s location.

Who protects your smartphone from cybercrooks?

Android malware analyst Filip Chytrý will be speaking at the CARO Workshop

Android malware analyst Filip Chytrý will be speaking at the CARO Workshop 2014

The avast! Virus Lab professionals work together to stop malware from attacking your Android mobile phone.

 

Filip Chytrý, an analyst in the avast! Virus Lab will Declare war against Android Malware, together with his colleague, Peter Kalnai, at the 8th International CARO Workshop held in Melbourne, Florida this week. CARO (Computer Antivirus Research Organization) is a technical gathering of malware experts from around the world who share case studies of mobile attacks, do real life attack demonstrations, and present plans for the identification and investigation of coordinated mobile threats.

Along with his specialized knowledge in Android malware, Filip is a really fun guy. I asked him a few questions, so that you could meet one of the AVAST professionals directly responsible for keeping tens of millions of Android smartphone users safe from threats.

DEBORAH Thanks for taking time during your preparations for CARO to meet our users via the AVAST blog. Your job analyzing Android-targeted malware didn’t even exist when you were a little boy. What early experiences with technology influenced your career path?

SAAB-(2)

Filip has worn cool shoes all his life

FILIP Define early. :) I’ve been addicted to PCs since childhood. I had my very first PC when I was 8 years old; some old piece of junk which was at that time probably older than I, but I still have remarkable memories of that time. So from that time on, I was influenced by technology. Even in my leisure activities, I concentrated on PCs. I went on to graduate from the School of Applications Cybernetics in Hradec Králové in Czech Republic.

DEBORAH  Protecting people’s desktop computers is how AVAST started, and now we’ve added free mobile security to our product offerings. How do we teach people to keep their smartphones and tablets safe just like their computers?
FILIP
Most people still do not realize that their smartphones actually have more computing power and abilities than the computer they had in their homes five-ten years ago. The capabilities of their devices are incredible. Data in portable devices may say more about you than data from your PC. You have location data there, pictures, social media information and so on.

Fake government ransomware holding Android devices hostage

Ransomware, which has already made its rounds on Windows, is now increasingly targeting the Android operating system. A new piece of mobile malware claiming to be the government under the name Android: Koler-A is now targeting users.

We have full control of your phone – give us $300 and we’ll give it back

Obrázek 1-1

The ransomware is pushed automatically from fake porn sites visited by Android users via a malicious .apk file that appears in the form of an app. The innocent appearance of the app deceives users and is a powerful social engineering tactic used by malware developers to trick people into installing malicious apps. The form of delivery is not the only thing that makes the app suspicious and potentially dangerous, but the access it seeks are highly unusual and alarming. The ransomware requests full network access, permission to run at startup and permission to prevent the phone from sleeping. Once installed the granted access allows the ransomware to take control of the device. The full network access allows the malicious app to communicate over the web and download the ransom message that is shown on the captive device. The permission to run at startup and prevent the phone from sleeping fully lockdown the phone, preventing victims from escaping the ransom message.

The ransomware localizes fake government messages, depending on the users GPS location, accusing them of having viewed and downloaded inappropriate and illegal content. What does the ransomware do next? Demands ransom of course! The ransom to regain access to the device including all of its apps, which it claims are all encrypted, is set at around $300 and is to be paid through untraceable forms of payment such as MoneyPak.

avast! Mobile Security safeguards against ransomware

Both AVAST’s free and premium mobile security apps, avast! Mobile Security and avast! Mobile Premium, protect customers from falling for the devious apps containing ransomware. AVAST detects this ransomware under the name Android: Koler-A and blocks its execution.

We recommend that everyone be cautious when downloading apps, especially from unofficial app markets. We also urge users to not open any files that have been downloaded to their device without their consent. Always check what apps want to access and in addition to being cautious, we advise people download antivirus to protect their devices. This new ransomware appearing on Android is the perfect example of how malware is starting to move away from the PC environment and into our pockets and there are no signs of this slowing down.

The 10 Commandments of Mobile Privacy

From governments to thieves to your wife – it seems that everyone has access to your private data.

avast! Mobile Security anti-theft helps track your lost phone

If you have a smartphone or tablet, people around you can discover your most deeply held secrets. You put all your private data and personal information there and… it’s at risk. The possibility of losing your phone or getting robbed is a major concern.

Is there anything that we can do to protect our private data? Some skeptics say no. I’m an optimist; I think there is always a way. Working for a security company makes us think that there is always a way to protect ourselves, to avoid danger, and to care about other users.

Lock your apps for privacy with avast! Mobile SecurityI’ve being collecting info for what I call the 10 Commandments for mobile privacy. Here are simple steps to help protect your privacy:

  1. 1. Use a PIN, password or pattern in your device. I’m lucky to have a phone where the numbers change their position on the screen and make the lockscreen even more secure. There are some apps that make your password “random” (obeying rules you’ve previously set).
  2. 2. Lock your most private apps. Lock your log in data but also your own messages, emails, personal notes, contacts, everything is in your pocket. offers the feature to secure even more sensitive parts of your device with the avast! Mobile Security App Locker that automatically asks for a PIN when you start the app.
  3. 3. Do not save banking or credit card credentials in your phone or, at least, not in the mobile browsers. Some banks, at least here in Brazil, have their own mobile app that never saves the passwords or PINs. Now, for Android, there are free password managers that adds a new security layer while browsing.
  4. 4. Do not be a happy clicker. People who expose themselves to scams or spam links, who download each single app they see from any kind of source put themselves at risk. OK, you’ll say this is not you. But, do you think twice on clicking in social media links or shares?
  5. 5. Do not take, send, save or share nude photos. No, this is not a moral commandment. It’s a privacy one. Read more…

You dropped your phone in the swimming pool. Now what?

avast tips help save your wet phone

At least it wasn’t dropped in the toilet!

How to save a wet smartphone

It happened with me, I jumped in the swimming pool with my phone in the pocket. Unfortunately, it was not the first time my phone was drenched. Some years ago, the villain was the rain. I was using a smartphone app to monitor my running pace and it started to rain. Not a light refreshing rain – no, a deluge, a Heavy rain. My phone was protected, but that was just too much rain.

At that time, I didn’t know what to do and made the wrong decisions. Some modern phones are waterproof, but others aren’t, and an accident involving water can be fatal. I’d like to share these hints with you on what to do if your phone decides to take a bath.

  • The first thing you should do NOW is a backup! You’ve heard this before, but have you done anything about it? It’s always better to be safe than sorry. Your photos, videos and musics, your apps and game data – everything could literally sink in water. We offer a simple, yet easy solution: avast! Mobile Backup protects your data against such accidents. Try now the free basic version from Google Play Store.
  • TURN YOUR PHONE OFF If your phone was dropped into water, the first thing to do is TURN IT OFF. And not only press the on/off button, but also remove the battery and cards completely. It’s a race against time. Each second is vital to avoid an electric shock and motherboard crash.
  • Let all the water flow freely. The best position for the phone is horizontal over a table on a dry piece of cloth. Do not rub, do not use cotton, do nothing… Just let the water drain out.
  • Dry the device carefully. After that, take a dry cloth or some absorbent paper to dry the device completely. Hold it with the screen facing up to drain all the water that could stay inside. Try not to shake it.
  • Be patient. Have a lot of patience. That’s the keyword here. Keep the phone open for a long time, at least 24 hours. Some technicians recommend to put it into a pot and fill with raw rice (or gel silica, if you have it with you) to absorb dampness.
  • After 24 hours, remove all the rice (or the small pieces of gel silica) and have patience again. Leave it open and exposed to air. Do not use hair dryers. Do not put the phone directly in the sun, because you can do more harm than good (harm to the screen, battery, or even the plastic parts.)
  • Only after other 12-24 hours you could try to put battery again and turn it on.
  • Of course, if you do not have luck, you’ll have to take it to technical assistance. But we wish you luck and that your phone will work again!

Besides getting wet, your phone can be lost or you could get infected with the ever-increasing malware being written for Android. Protect your phone for free with avast! Mobile Security & Antivirus. Get it on Google Play. Don’t be one of these careless people who neglect to protect their phones!

WordPress plugin vulnerability puts mobile visitors at risk

AVAST finds WordPress plugin redirector

AVAST finds new twist on WordPress plugin vulnerability

Today one of our colleagues came into our office and said, “Hey guys, I’ve been infected.” I thought to myself, yeah, how bad can this be? After a bit of digging we found the results were worth it; it turned out to be a really “interesting ” case of mobile redirected threats localized for each country.

All you need is one bad IP

The case was brought to us by Jakub Carda, a fellow AVAST employee who enjoys blogging in his free time. His WordPress site was compromised through a vulnerability in WordPress, more precisely OptimizePress. OptimizePress is a WordPress plugin that fully integrates itself into the WordPress CMS, helping bloggers optimize their blog’s design. A tiny mistake in the code of a file located in: lib/admin/media-upload.php made it possible for pretty much anyone to upload harmful content onto people’s WordPress sites, and plenty of websites have been compromised because of this.

Are software “Easter eggs” safe?

eggs02Easter egg hunts are a favorite activity for kids and adults alike, and on Easter Sunday, backyards, church grounds and even the White House will host their own competitions. Cyberspace has its own Easter eggs (a hidden message in software applications), and the hunt for them is just as fun as for real eggs. I asked Filip Chytrý, a researcher in the avast! Virus Lab specializing in mobile malware, about his favorite Easter eggs.

“I hate boiled eggs,” Chytrý joked, “but revealing Easter eggs in applications is pretty fun especially if you just have a clue, but don’t have any idea where to start.”

Can Easter eggs be malicious?

We’re not too keen on hidden code that no one knows about here at AVAST, so I thought it was a good question. Filip explained that to successfully make an Easter egg, the programmer has to hide the surprise from his fellow team mates and his employer, as well as the end user. It occurred to me that if programmers can hide fun things, it’s not a huge leap to hiding malicious things. Backdoors, for instance?

“We have not seen an Easter egg that might be considered as malware. There are plenty of original apps for Android which are modified to distribute malware by adding some kind of a downloader, but it’s without the user’s interaction. Easter eggs have remained harmless; Android apps – not so much,” said Chytrý.

Are there Easter eggs in mobile software?

Android developers have hidden Easter eggs within Android OS.

Easter eggs found in older version of Android OS

“There are Easter eggs in the latest versions of Android,” said Chytrý. “To access the Easter egg in your device, open the settings screen and tap About phone at the bottom of the screen. Locate Android’s version number on the about screen and quickly tap it several times.”

It worked with Android KitKat on my Nexus 4, but may not work in the modified OS of some device distributors. Find out how to access older Android OS Easter eggs.

AVAST helps user recover stolen phone; brother gets shot fighting thieves

Shahrukh Humayun's smartphone was stolen

Shahrukh Humayun’s smartphone was stolen

Two brave brothers fight off mobile phone thieves in Pakistan market.

We have heard stories about how avast! Mobile Security’s anti-theft feature has helped people recover their lost or stolen phones, but nothing as dramatic as Shahrukh Humayun’s tale of bravery.

Twenty year old Shahrukh and his 17-year old brother, Shoaib, live in Rawalpindi, Pakistan, the “twin city” to the capital, Islamabad. “Pindi” is a thriving urban area with good hotels, restaurants, museums, parks, and numerous markets and bazaars. It’s in one of those busy marketplaces that their story begins.

Shahrukh and Shoaib went to the market one day and were held up at gunpoint by thieves that demanded Shahruck’s HTC EVO smartphone.  Acting bravely to defend the expensive and precious device, Shoaib fought back against the bandits. They shot the teenager in the leg, stole the phone and fled the scene.

In his own words, Shahrukh described what happened:

Respected Avast! Team

I love the avast! android application as it helped me in catching the thieves who stole my mobile when I was in the market.

The story of the incident is that I visited market with my brother and I had a HTC EVO 3D X515m at that time. The thieves called me on the gun point while the area was empty. They asked me for the mobile and when my brother tried to take action they shot him on the leg.

Well, eventually I received an sms from avast that the sim have been changed. I checked my mobile as the GPS was active. I told the police about the incident on the same day and they found the thieves after 8 hours through the Google GPS connected with avast map.

Thank you avast!. Love you

1044816_478380138915077_764014148_n

Shoaib Humayun fought theives

All of us at AVAST were touched by the courage of these two young men when faced with danger. We are happy that our anti-theft product proved to be so useful in finding and recovering the phone. More than that, we were concerned about Shoaib. How has he fared since the incident?

Shahrukh gave us an update:

My brother is braver than me. As a result of that bravery he showed his best loyalty to me by fighting with those bandits and got shot on his leg. This event have passed 8 months and he got no sign of bruises on his leg. But thank God he is fine.

Thank you avast for helping me fight these bandits against their unlawful behavior for the country.
