A couple of days ago, a user posted a comment on our forum regarding apps harboring adware that can be found on Google Play. This didn’t seem like anything spectacular at the beginning, but once I took a closer look it turned out that this malware was a bit bigger than I initially thought. First of all, the apps are on Google Play, meaning that they have a huge target audience – in English speaking and other language regions as well. Second, the apps were already downloaded by millions of users and third, I was surprised that the adware lead to some legitimate companies.
The Durak card game app was the most widespread of the malicious apps with 5 – 10 million installations according to Google Play.
When you install Durak, it seems to be a completely normal and well working gaming app. This was the same for the other apps, which included an IQ test and a history app. This impression remains until you reboot your device and wait for a couple of days. After a week, you might start to feel there is something wrong with your device. Some of the apps wait up to 30 days until they show their true colors. After 30 days, I guess not many people would know which app is causing abnormal behavior on their phone, right?
Each time you unlock your device an ad is presented to you, warning you about a problem, e.g. that your device is infected, out of date or full of porn. This, of course, is a complete lie. You are then asked to take action, however, if you approve you get re-directed to harmful threats on fake pages, like dubious app stores and apps that attempt to send premium SMS behind your back or to apps that simply collect too much of your data for comfort while offering you no additional value.
An even bigger surprise was that users were sometimes directed to security apps on Google Play. These security apps are, of course, harmless, but would security providers really want to promote their apps via adware? Even if you install the security apps, the undesirable ads popping up on your phone don‘t stop. This kind of threat can be considered good social engineering. Most people won‘t be able to find the source of the problem and will face fake ads each time they unlock their device. I believe that most people will trust that there is a problem that can be solved with one of the apps advertised “solutions” and will follow the recommended steps, which may lead to an investment into unwanted apps from untrusted sources.
Avast Mobile Premium detects these apps, protecting its users from the annoying adware. Additionally, the apps’ descriptions should make users skeptical about the legitimacy of the apps. Both in English and in other languages such as German, were written poorly: “A card game called ‘Durak‘ – one of the most common and well known game“.
The apps‘ secure hash algorithm (SHA256) is the following: BDFBF9DE49E71331FFDFD04839B2B0810802F8C8BB9BE93B5A7E370958762836 9502DFC2D14C962CF1A1A9CDF01BD56416E60DAFC088BC54C177096D033410ED FCF88C8268A7AC97BF10C323EB2828E2025FEEA13CDC6554770E7591CDED462D
The Avast Mobile Security Team will be introducing its latest suite of apps and solutions at this year’s Mobile World Congress in Barcelona, March 2 – 5.
The team, including Jude McColgan, President of Mobile, and Daniel Cheng, Head of Worldwide Mobile Sales and Marketing, will be participating in this must-attend conference for mobile industry leaders, visionaries, and innovators.
The Avast team are leaders in securing the mobile ecosystem as it expands into the retail, banking, and health services industries. Along with interesting discussions about the latest security threats and vulnerabilities for Android and iOS devices and how users can protect themselves from those threats, our team will show users how they can free their phone from unnecessary files to gain valuable storage space on their mobile devices.
New threats and trends
Mr. McColgan and Mr. Cheng will introduce a solution that addresses Wi-Fi security issues. Many people don’t know that connecting to Wi-Fi networks on-the-go at cafes, airports, or hotels make them vulnerable to hackers. Without the protection of a virtual private network (VPN), hackers can gain access to people’s emails, browsing history, and personal data. Now, routers are increasingly becoming targets for hackers, harboring new risks for iOS and Android smartphones and tablets. Avast will be revealing new research data, then introducing a solution for this threat at Mobile World Congress.
Storage on your smartphone and tablet can be a challenge especially when social media, video, music streaming, and news reader apps pile up data that eats up valuable storage space. Avast will showcase a new solution that addresses this problem.
If you are attending Mobile World Congress, please stop by and visit the Avast team at stand 5K29 in Hall 5.
For the rest of us not lucky enough to travel to Barcelona during the Mobile World Congress, visit the Avast blog and Facebook page where we will keep you updated on all the announcements and happenings. Take a look at some of the fun from last year’s event.
A few precautions can make a huge difference in the safety of your phone and the important things you saved on it.
We talk a lot about protection and privacy here in our blog. It’s a bit obvious as our “life” is in our devices nowadays: Photos of our last trip or our loved ones, videos of our children playing and growing up, contacts both professional and personal. All our precious and irreplaceable data is stored in these little machines. Take a minute of your time and follow us in this easy tour to protect them and save a lot of time and headaches.
1. Set your lockscreen
You wouldn’t leave your home door unlocked, would you? Same goes for your phone with all your private data. Set a password or PIN to prevent direct and easy access to your phone. Gestures and face recognition are less secure, but are better than nothing.
2. Hide your passwords from nosy people
You will argue that people around you can look over your shoulder and see what PIN or password you’re typing or gesture you make. Generally, we’re not worried about trustworthy people around us, but what about strangers in a public place like a bus or train? Open your phone settings and hide your passwords by unchecking the option: Settings > Security > Make passwords visible.
3. Protect your apps with a PIN
Not all apps are equal when it comes to security and privacy. Probably the weather app or calculator won’t keep your personal info. However, your messages and banking apps will thank you if you help them to keep their data private. You can imagine what might happen if your kids to open a specific app while they’re playing in your devices. Use Avast Mobile Security to set a PIN to block access to your apps. As an extra security measure, it will be good that your lockscreen and Avast PINs are different ones.
4. Disable installation of apps from unknown sources
If you do not use other app stores besides Google Play, then uncheck the option “Unknown sources” in your phone’s Security Settings page. Even the Google Play Store sometimes allows malware to get by. It’s well known that most Android malware are fake apps disguised as legitimate apps, so double check the publisher. Be cautious of downloading from fake sites disguised as official ones – check the URL. Avoid completely pirated and cracked sources.
5. Set Avast Mobile Security to scan any app before installing
If you really need to use legal third party stores, like Amazon or F-Droid, please be careful: Keep Avast Mobile Security always on. You know that Avast scans any installed and running app. But do you know that you can set it to scan any app that is about to be installed? After you’ve installed Avast, when you’re about to install a new app, the phone will ask you if you want Avast or the default installer to handle the installation by default. Use Avast, it will scan and then release the app to the default installation process.
6. Disable USB Debugging
This tip is for advanced users. If you have enabled Developer options into your device (and you will know exactly if you did as you’re an advanced user!), please, turn USB debugging off. You will protect your device from outside abuse (via adb connections) if you do so. You don’t need it to be on all the time.
7. Install and set Avast Anti-Theft
This is an old tip, but it’s so important that it should be on all smartphone safety tips lists. Just note that installing is not enough. You need to properly configure Avast Anti-Theft (don’t worry, there is an easy wizard for it) step-by-step. It’s good to check if your location services are properly set also, otherwise, it will be difficult to track it. In other words, go to Settings > Location Access and set High accuracy mode.
We’ll talk about the other 7 tips in next days, so come back to the Avast blog.
It’s European #DataProtection day! Every day we visit websites and willingly hand over our name, address, and credit card number. Have you ever thought about what happens to that data or what your rights are?
Members of the European Union (EU) enjoy a high standard of protection of their personal data. The Digital Agenda for Europe lays it all out for you on their website. Here’s a summary:
The burden to protect you is on organizations
The EU Data Protection Directive ensures that personal data can only be gathered under strict conditions and for legitimate purposes. Organizations that collect and manage your personal information must also protect it from misuse and respect certain rights. One of the objectives is that organizations notify their customers, in plain language, what information is collected and how it is used as well as get permission before using any personal information.
One of the stumbling blocks has been the so-called one-stop-shop for businesses and citizens in each member state in which authorities will handle citizens’ complaints about any breach of the rules. There are just as many ideas on how to run it as there are EU member states.
You must be notified of cookies and data breaches
The Directive on Privacy and Electronic communications (ePrivacy Directive) ensures that all communications over public networks maintain a high level of privacy. For example, this directive requires website owners marketing online to EU citizens to obtain consent from users, via some kind of opt-in, before implementing cookies or other technologies to capture online visitor information. (See below for information on managing your cookies.)
If your data is stolen, the ePrivacy Directive states that you should be notified. That’s good because data theft can result in identity theft or fraud, damage to your reputation, loss of control over your personal data or a loss of confidentiality.
However, this fall, the rules changed slightly and now businesses don’t have to notify consumers that their personal data has been lost or stolen if the data has been encrypted. The ministers figure that the business has “appropriate technological protection measures” to protect the data that has been lost or stolen from being accessed by people not authorized to see it.

Privacy plays a growing part in customer buying decisions. With every data breach, trust is eroded further.
Privacy and security are intertwined when it comes to our individual information. Consumers are becoming increasingly aware of the value of their personal data, so that means that businesses have to step up and do a better job of securing that data. Identity theft is the #1 fear of consumers, but for your business the risk is loss of trust and brand damage.
Since trust is the core of any transaction it’s important to know how privacy factors into your customer’s buying decisions. Research shows that almost 40% of consumers made buying decisions based upon privacy. When looking at who these people are, it was found that these individuals are aged 46-65 and have the highest incomes. But don’t rely on the business of the younger generation to supplant that once trust is lost; 27% of millenials abandoned an online purchase in the past month due to privacy or security concerns.
To mark Data Privacy Day on January 28, the following Privacy is Good for Business tips were created by privacy experts in civil-society, non-profit, government and industry and aspire to help business address the public’s growing privacy concerns:
- If you collect it, protect it. Follow reasonable security measures to keep individuals’ personal information safe from inappropriate and unauthorized access.
- Be open and honest about how you collect, use and share consumers’ personal information. Think about how the consumer may expect their data to be used.
- Build trust by doing what you say you will do. Communicate clearly and concisely to the public about what privacy means to your organization and the steps you take to achieve and maintain privacy.
- Create a culture of privacy in your organization. Explain to and educate employees about the importance and impact of protecting consumer and employee information as well as the role they play in keeping it safe.
- Don’t count on your privacy notice as your only tool to educate consumers about your data practices.
- Conduct due diligence and maintain oversight of partners and vendors. You are also responsible for how they collect and use personal information.
Question of the week: I use two-factor authentication when logging into my accounts to keep them safe, but what happens if I lose my phone? Can I still access my accounts?
Security-minded individuals know the benefits of using two-factor authentication to keep their online accounts safe. For those of you who are not familiar with it, two-factor authentication is a security process which uses a combination of two different components, like something that you know, a master password or PIN, for instance, and something that you possess, like a token which can generate a number code or, more conveniently, your smartphone.
Using these two things in combination can provide unique identification when entering a site because you provide the password as well as a one-time use security code generated by your security token. If someone learns your password, your accounts are still protected because they need the security code too. Two-factor authentication can reduce the incidence of identity theft and phishing, and we suggest the use of it.
There are a number of authenticator apps made for Android smartphones. For example, Google Authenticator lets you use a security code and your own password for sites and services like Facebook, Dropbox, Evernote, and WordPress. The app creates a link between your account and your device.
I lost my phone. How do I access my accounts?
If you are so security-minded that you use two-factor authentication to begin with, then you have probably taken precautions before you lose your phone. The majority of authenticator services allow a way to recover your access and remove the authorized device from your account. That is, if you change your mobile device, then you can disable the two-factor authentication from your account before doing so. Most commonly, you would use backup codes, send the codes via SMS to a trusted backup phone, or use a trusted computer. Sometimes, the service providers take several business days to verify your identity and, if possible, grant you access again.
But, if you failed to plan ahead and you lose your phone or if you buy a new smartphone without disabling the account, to use two-factor authentication again, you’ll need to install an authenticator app on your new device. The old device and the old backup codes won’t work anymore. Some of the sites you have synced to may also have their own procedure, for example, Dropbox.
Recently, an app is making the use of this security measure much more convenient. Authy is an app that manages your two-factor accounts on Android devices, iPhones, and even your PC. Any of these devices could be used to generate tokens and sync with each other. One authorized device could de-authorize a stolen one. A master password could block the access to Authy in these multiple devices and your settings are all kept encrypted locally. Neither Authy’s developers nor hackers would be able to access the tokens.
Maybe this complex recovery process is what does not make two-factor authentication omnipresent. But, after all, you just need to take a few precautions to increase your security a lot.
Of course, it’s better not to lose your devices and for this, you should install and configure Avast Anti-Theft, which can help you find a lost device and even recover a stolen one with its tracking features. It can be downloaded and used for free from the Google Play Store.
Make Avast quiet when you are playing games or giving presentations.
We know you love Avast, but when you are giving a presentation to the big boss, or concentrating on playing an important game, it may not be the best time for a popup that says your computer is running slowly to appear. That’s why we made it easy for you to silence Avast.
Activate the Silent/gaming mode when don’t want to be interrupted. This will cause Avast to run in silent mode when a full-screen application is running. This means your games or other full-screen applications will not be interrupted with annoying popups or other messages.
Turn this mode on quickly by clicking on the orange Avast icon located in your computer’s system tray. Right-click on the Avast icon and a short menu will appear. Click on Silent/gaming mode to turn it on.
You can also access this option within the main user interface. Go to Settings>General and check the box for Silent/gaming mode. This will disable messages, popups, and alerts in Avast.
Turn off sounds
Silence notifications: Open the Avast user interface. Click Settings>General>Sounds and uncheck the Enable Avast sounds box. You can also uncheck the Voiceovers within the Sounds settings.
Choose the notifications you want to silence: Avast has six “events” that have notifications associated with them.. These events are Threat detected, Suspicious item detected (we suggest you keep these two on), Potentially unwanted program (PUP) detected, Scan complete, Automatic update, and Firewall query. You have the option to uncheck these boxes as well.
Turn off popups
Occasionally, we offer our users great products like GrimeFighter but we understand if you don’t need to see the notifications anymore. Our customers who have a paid-for version of Avast, have an option for you to turn those off completely. Read more…
Take these steps to ensure you don’t give away your data when you sell your old smartphone!
You got a new device for Christmas and have finally finished migrating the data and apps from your old one to the new one. Now you’re thinking about what you can do with your old smartphone or tablet, and you come up with two alternatives: Sell it or give it away.
You’ve heard about some sites on the internet where you can sell your phone, so you do some research and decide on a fair price for your used device. Register yourself at the site and… Wait. Something suddenly occurred to you.
Will the new owner be able to see my personal stuff on my old phone?
You’re right to think about that because Tens of thousands of Americans sell themselves online every day. Not only do they sell the devices, they sell themselves as all the personal data could be recovered.
If you don’t want a stranger to see your selfies, discover your bank account details and your credit card numbers, and even some problematic Snapchats and SMSs… you need to do something. Do you remember the celebrities photos scandal?
So what to do? Use a hammer? Well, there are other options.
1. Backup your important data
Much of our lives are stored in our smartphones: Photos, music, videos, personal and professional contacts, call logs and SMSs. And you want all this stuff in your new device, don’t you? Avast Mobile Backup was specially designed to make this easier for you. It makes a backup in your Avast account (or in your Google Drive storage) and then allows you to recover them in a new device: All your paid apps and games (with their data) will be restored.
If you have a MicroSD card, remove it from your device and insert it into your PC, making a full copy and paste operation for all files. Remember that many Android devices store photos and other media files in the DCIM folder of the internal memory. Back it up, too.
The nightmare is back! Your security could be seriously compromised if you do not act now. Install and update your Avast for PC before is too late. The original version of CryptoWall was discovered in November 2013, but a new and improved variant of the CryptoWall ransomware starts to infect computers all over the world last days. It’s the CryptoWall 3.0. Some sources estimate that it has already infected over 700,000 computers up to version 2.0.
CryptoWall is a malware that encrypts certain files in your computer (and secure delete the original ones) and, once activated, demands a fine around $500 as a ransom to provide the decryption key. You’re asked to pay in digital Bitcoins in about 170 hours (almost a full week). After that period, the fee is raised to $1000.
You could be asking why haven’t the authorities blocked the financial funding of them? They use unique wallet ID for each victim into their own TOR anonymity servers. For the user to be able to pay the ransom, he needs to use a TOR-like connection called Web-to-TOR. Each TOR gateway redirects the victim to the same web page with the payment instructions. The commands and communication control is now done using Invisible Internet Project (I2P) instead of Tor.
Infection could reach you in various ways. The most common is as a phishing attack, but it also comes in email attachments and PDF files. The malware kit also abuses various vulnerabilities in unpatched – read non up-to-date – Flash, Java, browsers and other applications to drop the CryptoWall ransomware.
How Avast prevents the infection
1. Avast Antispam and antiphishing protection prevents some vectors distribution.
2. Virus signature block all known ransomwares versions. Remember that Avast automatic streaming updates releases hundreds of daily updates for virus definitions.
3. Community IQ intelligence and sensors of our more than 220 million users that detects malware behavior all over the world. See how it works in this YouTube video.
4. Keeping your software updated is another security measure that prevents the exploit of their vulnerabilities. Learn how Avast Software Updater can help you with this job.
What more can I do?
Avast also helps in prevention of this disaster through its Avast Backup that allows you to keep all your important files in a secure and encrypted way. We also recommend local backup, as the new malware could also attack other drives and even cloud storage. Did you know that Avast Backup also performs local copies of the files? You can enable it at Settings > Options > Local backup, and configure the backup location (better an external drive) and also versioning of the files. Remember to disconnect the external drive from the computer (and the network) to prevent infection of the backups by CryptoWall and further encryption of the files.
Only four and half minutes of your time, and you’ll know the highlights of Avast 2015.
Avast 2015 is very easy to use, and many people just install it and let it do its job silently in the background. We designed it that way, but for those of you who want to know more about the features of Avast, we created a video guide to help you get the most out of your security protection.
The core of Avast Antivirus is real-time active protection comprised of the Web, Mail, and File System Shields. These can be accessed from the user interface. Open Settings and go to Active protection.
