The Avast bi weekly wrap-up is a quick summary of what was on the Avast blog for the last two weeks.
Most everyone knows their PC needs antivirus protection, but they don’t think about their smartphone. These days smartphones are just about as powerful and have as much or more personal information as our desktop PC at home. We answer the question do Android devices really need protection?
The answer is a resounding YES. The Avast Virus Lab gives us an example from a trusted download source, Google Play: A porn clicker app slipped into Google Play imitating the popular Dubsmash app. If we cannot completely rely on trusted app stores to weed out nasty apps, then it’s time to add an extra layer of security.
Once you decide that you do want to protect your Android device, you can be confident in Avast Mobile Security, Avast’s free security app available on Google Play. A survey by AV -Comparatives said that Avast was the #1 choice for mobile security in the entire world. No need to wait any longer to protect your smartphone or tablet.
One of the challenges with using a smartphone for so many activities, is that the battery gives out before we do. Our new free app Avast Battery Saver raises the bar with new Wi-Fi based smart profiles that can increase battery life by an average of 7 hours.
Avast Battery Saver has only been available for a month or so but already 200,000 customers have downloaded it from the Google Play Store. For Earth Day we highlighted battery saver users for their positive impact on the environment. Who knew that Avast Battery Saver would be so green? A cool infographic shows just how much they saved - not only from their own battery - but in energy costs too. Now Earth Day can be everyday!
Small and medium-sized businesses (SMBs) run the risk of data breaches just like there Enterprise cousins. Luke Walling, the General Manager of Avast for Business, explains that the biggest threat to SMBs is not actually hackers sitting somewhere far away. The biggest threat to your SMB could be sitting in your office!
Speaking of Avast for Business, our new disruptive free security offering for SMBs has 75,000 new customers in just 2 months. If you have a start-up, a small business, if you work in a school or non-profit organization, then it’s time to stop paying for security protection.
Our researchers are constantly surprised by the creativity of malware authors. Recently, they found a new way cybercrooks trick people in giving up their banking information. It’s a crafty combination of spam email, social engineering, and a macro code embedded in an innocent looking Word document.
Most people have security protection on their computers. That’s great when there are things like the banking malware we wrote about. With all that great protection why is it that they don’t trust the warnings? The Avast Virus Lab explored why some people would rather be right than believe a malware warning.
It’s very common to find people concerned about Windows viruses and malware that say, “Oh, my PC is protected by Avast Antivirus, but we don’t need it for our smartphones and tablets.”
With more than 230 million Avast Antivirus customers, we see “only” 60 million or so Android users of Avast Mobile Security. Many more mobile devices are sold every second than desktops and notebooks together. Why are people not as concerned about the security of their smartphone as their desktop?
The AV-Comparatives survey that we wrote about yesterday in Avast Mobile Security is the #1 choice for Android users says that Android users in North America protect their phones more than anywhere else in the world with 31 percent of respondents reporting they have protection. South America, Asia, and Europe are much lower at 17 percent.
What about the rest of the Android users?
- Do you realize that mobile malware is increasing?
- Do you realize that you (most probably) have much more personal info in your smartphone than your PC? Like photos, selfies, contacts, videos, and also banking and financial information.
- What if one of your apps is using your personal info against you like the Dubsmash 2 app we just discovered?

The most popular mobile security product in the world is Avast Mobile Security.
In their annual IT Security Survey, AV – Comparatives asked, Which mobile anti-malware security solution do you primarily use on your smartphone?
Avast took 1st or 2nd place on four continents: Europe, North America, Asia, and South/Central America.
How great is the risk of infection on an Android smartphone?
The risk of your Android smartphone becoming infected depends on several factors. In the US and Europe most people use official stores such as Google Play for installing apps. The risk is much lower than in many Asian countries, especially China, where app stores are not subject to stricter controls. Because of these unofficial app stores, along with numerous rooted phones, the chance of installing a dangerous app is highly increased.
In Asia, the smartphone is often used as an alternative to the PC. People frequently use it for online banking which make them vulnerable to Zeus Trojan malware. Zeus is commonly delivered via a link or an attachment in a phishing message or through a text message via WhatsApp, SMS, or Twitter. This threat will similarly increase in Europe and the US as banking apps get more popular.
An ounce of prevention is worth a pound of cure
The Avast Virus Lab has more than one million samples of mobile malware in its database, and reports that 2,850 new mobile threats are created every day by hackers. The threat situation can change quickly and dramatically so it is best to use preventative protection and install security software on your smartphone. At this point though, protecting important data in the event that your phone is lost or stolen is more critical than malware protection.
The AV-Comparatives survey says that Android users in North America protect their phones more than anywhere else in the world with 31 percent of respondents reporting they have protection. South America, Asia, and Europe are much lower at 17 percent.
Protect your Android smartphone and tablet with Avast Mobile Security and Avast Anti-Theft: Free from the Google Play store.
Everyone from celebrities like Lena Dunham to Hugh Jackman are using the (currently) seventh most popular app available on Google Play: Dubsmash. Dubsmash is an app with more than 10 million Google Play installations that lets users choose a sound, record a video to go along with the sound and send their dub to their friends or social media channels. Dubsmash is not only widely popular amongst teens and celebs, but the app has also caught the attention of malware authors.
Avast recently discovered “Dubsmash 2” (with the package name “com.table.hockes”) on Google Play – and no, it was not the bigger and better version of the original app. The app is a so called “porn clicker” and was installed 100,000-500,000 times from the Google Play Store. We contacted Google when we discovered the rogue app and it was removed from the Play Store shortly thereafter. Once the app was installed there was no evidence of an app named “Dubsmash 2” on the user’s device, instead the app installed an app icon named “Setting IS”. This is a common trick malware authors use to make it harder for the user to figure out which app is causing problems. This should also be the user’s first clue that something shady is going on. The “Settings IS” icon looked very similar to the actual Android Settings icon (see screenshot below).
The app’s mischievous activities could be triggered by two actions. The first possible way was by simply launching the “Settings IS” app and the second, which occurred only if the user had not yet launched the app, was via the BroadcastReceiver component within the app. BroadcastReceiver observed the device’s Internet connectivity and if the BroadcastReceiver noticed the device was connected to the Internet, the app’s true functions would be triggered.
If the “Settings IS” app was opened by the user, the Google Play Store would launch to the actual “Dubsmash” app download page.
Once activated, the app sent an HTTP GET request to an encrypted URL. If the request returned a string containing the character “1” two services would begin to work: MyService and Streaming. Using this method the author could also effectively turn off the start of the services remotely.
The second service, the Streaming service, was fairly similar in structure to the MyService component in that it also scheduled a task to run every 60 seconds. The main difference to MyService, is that users could notice the Service tasks did not run secretly in the background. The task would check for changes in the device’s IP address or date. If either of them had changed, a video would launch in the device’s YouTube app. The YouTube app needed to be installed on the device for this to function properly. The video address was also obtained from an encrypted URL.
After decrypting and further examining the URLs and the video from YouTube, the Avast Virus Lab came to the conclusion that the malware most likely originated from Turkey. The developer’s name listed on Google Play and YouTube hint to this.
We suspect the app developer used the porn clicker method for financial gain. Through clicks on multiple ads within the porn sites, the app developer probably received pay-per-click earnings from advertisers who thought he was displaying their ads on websites for people to actually see.
Despite being undesirable, but basically harmless to the user and less sophisticated than other malware families such as Fobus or Simplocker, this app shows that although there are safeguards in place, undesirable apps that fool users can still slip into the Google Play store.
If you installed Dubsmash 2 (package name “com.table.hockes”), you can delete the app by going into Settings -> Apps -> find “Settings IS” and then uninstall the app.
The Avast Mobile Security application detects this threat as Android:Clicker. SHA-256 hash: de98363968182c27879aa6bdd9a499e30c6beffcc10371c90af2edc32350fac4
Thank you Nikolaos Chrysaidos for your help with the analysis
We’ve recently told you about Avast Battery Saver, an application which saves your Android’s power without hassle. It optimizes phone settings such as Internet connectivity, screen brightness, and timeout according to your needs. We’d now like to announce an exciting new feature of the app: Wi-Fi-based smart power profiles. These profiles are activated automatically based on designated local Wi-Fi networks that are detected. Users can now assign specific wireless networks to be used within their home or work smart profiles. Not only are Wi-Fi-based profiles more precise than GPS-based profiles, but they are also more efficient and require less energy to detect.
In contrast to other battery-saving applications, Avast Battery Saver learns about your daily routine and thus suggests the best smart profiles for your phone. It doesn’t require you to change your behavior or usage, nor does it affect voice calls, text messages, or the ring volume of your phone.
“Everyone needs more battery life for their mobile devices, but most battery savers shut down the wrong apps,” said Jude McColgan, Avast’s President of Mobile. “Avast Battery Saver learns which apps are most important to the user, and shuts down only those that are less used.”
Avast Battery Saver significantly improves battery life, saving up to 20% on one charge — and it’s free from the Google Play Store.
New Wi-Fi-based profiles have been added to make the app’s convenient features significantly more efficient
- Smart profiles activate automatically based on time, location, user-designated Wi-Fi networks and battery level.
- App consumption detects and permanently stops apps that drain too much battery life.
- Precise estimate of remaining battery life based on actual phone usage and historical data. Battery level is displayed in a percentage and time remaining in status bar notification.
- The application can turn off Wi-Fi when there are no known hotspots nearby.
- Your phone limits connections to the Internet to every 5, 10, 15 or 30 minutes, based on your current profile configuration, when its screen is turned off.
- Emergency mode is activated when your battery level is very low, and it turns off all functions that require significant energy, saving power for when you really need it (e.g. Wi-Fi, data connection, Bluetooth or GPS).
The app currently works with the following four profiles: Home, Work, Night, and Super-Saving Emergency Mode. You can easily access the list of profiles by clicking the “Smart Profiles” button on the app’s home screen. Avast Battery Saver is available for download in the Google Play Store.

Many smartphone owners are more worried about losing their device then they are about becoming infected with malware. That’s why we created Avast Anti-Theft. Make sure you have the latest version of our free app so if your phone gets lost, you can track it via your My Avast account or using SMS notifications from your friend’s phone. Turned Android auto-updates off? Manually update Anti-Theft to stay protected. explains how you can use Avast Anti -Theft to recover your lost Android device.
The mobile development team released a handy little app called Avast Battery Saver. This free app from Google Play helps you save some battery power. But not just any app can do it. The blog post Fear and loathing on Google Play: An in-depth look at today’s battery saving and cleaning apps gives us the scoop on apps that promise to save battery life with task cleaning.
How to extend the life of your phone’s battery is a question that we all have when the juice starts running out. The Avast Battery Saver app can help save about 20% but there are other ways to save battery life. We give you the tips and also share the future of smartphone batteries.
The unsecured Wi-Fi hotspot at the local cafe can be bad news if thieves capture your login credentials. Android users with Avast Mobile Security have a built-in feature called Wi-Fi Security that warns them if any issues are detected. We are now seeking iOS beta testers for an app called Avast SecureMe that will include the same type of feature for iPhone users. Check our blog Wi-Fi Security feature foolproofs your network connections both in public and at home and scroll down to the bottom for the beta test sign up link.
Cybercrooks use a variety of attack vectors to reach their victims. Targeted spearphishing attacks use email messages to trick people into providing sensitive information while malicious apps for Android disguise themselves as innocent games. The scary ransomware locks up all your files and demands ransom for the key to unlock it – on both PCs and and mobile devices! Avast keeps you aware of cybercrooks latest tricks in Don’t take the bait: Beware of web attack techniques.
Wi-Fi Security is a feature that is available for Android users within the Avast Mobile Security app as well as within Avast SecureMe for iOS. The feature’s job is to scan Wi-Fi connections and notify you if it finds any security issues including routers with weak passwords, unsecured wireless networks, and routers with vulnerabilities that could be exploited by hackers.
While conducting user testing, we found that 22% of Avast Mobile Security users make use of the Wi-Fi Security feature, making it the 2nd most used feature within Avast Mobile Security.
“Avast SecureMe and Avast Mobile Security offer users a simple, one-touch solution to find and choose safe networks to protect themselves from the threat of stolen personal data,” said Jude McColgan.
Wi-Fi Security scan notifies you of any issues that are detected
From all the users who tested the Wi-Fi Security feature, more than 10% of the scans performed returned some kind of problem, such as the use of non-encrypted passwords or a router that is susceptible to security threats. The Wi-Fi Security feature currently performs checks for the following four key elements:
- Non-encrypted, unsecured wireless networks
- Networks with weak encryption
- Weak router passwords
- Routers with known security issues
What’s the risk that my personal data will be stolen?
If you use unsecured Wi-Fi when you log in to a banking site, for example, thieves can capture your log in credentials which can lead to identify theft. On unprotected Wi-Fi networks, thieves can also easily see emails, browsing history, and personal data if you do not use a secure or encrypted connection like a virtual private network (VPN). See our global Wi-Fi hacking experiment to see how widespread the threat really is.
Wi-Fi Security offers two solutions to defend against malware threats
After the Wi-Fi Security feature has scanned your device, you’re presented with two options:
1) Launch Avast SecureLine VPN
2) Click the ‘How to resolve’ button
The first of the two options is meant to be used when you’re connecting to public networks – it’s ideal for cafes, airports, or hotels. On the contrary, users should opt to resolve detected threats if they’re browsing at home using their own devices. When taking this route, you’re redirected to the Avast website in order to set up your router in accordance with our guidelines.
How do I get the Wi-Fi Security feature onto my device?
Avast SecureMe will soon be available in the iTunes Store. Before its widespread release, we will be conducting an invitation-only public beta test. Please sign up here, and the SecureMe team will contact you. If you have already downloaded Avast Mobile Security for Android then you’re all set to start using the Wi-Fi Security feature (you’ll find the “Wi-Fi Security” button on the app’s dashboard). For those yet to download Avast Mobile Security, it is available now from the Play Store.
If you have a smartphone, you are basically carrying around a pocket-sized laptop with a built-in camera and phone. Denser electronics have allowed for some powerful features to be built into a small package, but the weak link is the battery that runs it all. Battery energy has yet to match the quick growth of features on electronic devices.
Where does the juice go?
The power it takes to keep the device running all day depends upon what you do as well as your operating system, settings, and network (Wi-Fi, CDMA/GSM, 2G/3G/4G), but battery manufacturers say typical Lithium-ion (Li-ion) batteries provide up to ten hours talk time and up to 300 hours standby time.
Apps drain the battery. They sit in the background pinging servers, keeping track of where you are, and waiting for signals. Wi-Fi, Bluetooth, and GPS use power looking for routers and satellites or other Bluetooth devices. The display uses lots of power too, especially at full brightness and if you do graphic-intensive activities like play games.
The environment also has an impact on Li-ion batteries. They suffer from stress when exposed to temperatures above 30°C/86°F. This high heat accelerates capacity loss which cannot be restored. Likewise, cold can decrease electricity flow, making your device sluggish.
When do I need to replace my battery?
Conventional wisdom says you’ll probably need a new phone battery each year. Factors like charge and discharge cycles, exposure to high temperatures, and aging decrease performance over time. Manufacturers say the life of most Li-on range between 300 and 500 cycles. Beyond this lifespan, batteries gradually diminish below 50 percent of the original capacity.
If you notice that your battery depletes rapidly, fails to hold a full charge, or feels abnormally warm then most likely it’s time to replace your phone’s battery.
How to save battery life?
- Use Avast Battery Saver. Our free app from Google Play optimizes phone settings using ‘Smart profiles’ which activate automatically based on time, location, and battery level. This saves up to 20% on one charge.
- Avoid full discharges and charge the battery more often between uses.
- Limit exposure to extreme temperatures, especially heat. Don’t leave your phone in a hot car. Room temperature is best.
- Lower your screen brightness. You can experiment, but usually anywhere above 50% is still readable. Some phones let you set it to auto-adjust.
- Turn off vibrate, ringtones, and the flash on your camera.
- Keep apps updated. The updates often improve battery usage by making the apps more efficient.
- When in areas with no cell coverage, turn the device to airplane mode or even turn it off. Otherwise, the phone will continue to search for a signal and that eats battery.
- Limit graphics-intensive activities like gaming and watching videos.
- Turn off WiFi, Bluetooth, and GPS when you don’t need them.

The future of smartphone batteries
The race for a safe, cheap, long-lasting, energy-rich battery is on. With electric cars, wearable tech, and the Internet of Things running our households, inventors, scientists and business people are searching for the breakthrough that will change batteries forever. The next-generation of batteries may well be built with silicon-based electrodes, take advantage of the oxygen we breathe to recharge power cells, or be organic.
Just last week, a super-fast (1 minute!) chargeable aluminum-ion battery with a high-charge storage capacity developed at Stanford University was announced. This low cost, durable (it was able to withstand more than 7,500 cycles without any loss of capacity) battery is not ready to be mass produced, but it holds promise.
Until that time comes though, used the Avast Battery Saver free app to extend the life of your phone’s battery.
Avast Battery Saver quickly and easily helps you to save your Android’s battery life
Mobile devices are currently evolving at an exceptional rate. Processor speed, display quality and connectivity options have changed dramatically over the past few years. However, battery capacity still seems to be struggling to keep up with the evolving capacity needed to power the enormous amount of new processors and displays.
According to a recent survey answered by 20, 000 people, 60% of Android owners are not satisfied with their device’s battery life.
There are a huge amount of Android applications trying to solve that problem, yet most of them fail to do so. When examining the features available on these apps, it becomes easy to see why many of them haven’t achieved complete success.
Task-killing is the most popular feature available not only within many battery saving apps, but also within cleaners and phone boosters. It most likely originated in Windows’ desktop operating system. Since users had first become accustomed to closing programs on Windows when their PCs began to slow down, this behavior transferred over to mobile devices when the users began to use Android.
However, Android’s system works differently. Android aims to keep RAM full in order to switch between applications more quickly. If there is no free RAM left, Android kills less recent applications. Thus, there is no need for the user to shut down the apps manually. Furthermore, task-killing actually slows down devices because each time an app is shut down, its data must be loaded to RAM again.
Try it yourself
Here’s a small test that you can try: install a task-killer, RAM booster or battery saving app that “cleans” RAM. Click the main button (it’s usually called “Optimize” or “Boost”). You’ll see several apps killed. Then, wait for a few seconds and try it again. Nothing will happen, as you’ve just killed everything.
Now, uninstall or clear the data in the tested app. After you click the “Optimize” button again, almost all of the apps you’ve just killed are shown to be killed again. Looks strange, huh? It might appear that the “Optimize” button doesn’t do anything. In reality, it does kill applications. The trick is that many apps start directly after being killed using Android’s WakeLock feature. Apps with an “Optimize” button have a timer which prevents users from seeing that killed apps are running again after a few seconds. Because of this, there is no sense in using “Optimize”.
More info about task-killing can be found here:
How can I actually save my device’s battery life?
A couple main factors that contribute to saving battery is turning off certain features of your device including Wi-Fi and mobile data and limiting display brightness and timeout.
Avast now brings you Avast Battery Saver, an application which saves power without hassle. It optimizes phone settings such as Internet connectivity, screen brightness, and timeout according to your needs. Smart power profiles are activated automatically based on time, location, and battery level without sacrificing the activities you love most.
Avast Battery Saver also contains a powerful tool to solve the issue of apps draining your battery’s lifespan while not being used. You have the ability to see how much battery every app is draining and force stop any that you’re not currently using. Unlike task-killing, force-stopping is Android’s native solution to prevent apps from unnecessarily running in the background. Once force-stopped, an app will not run again until it’s next manually opened.
Ready to save? Download Avast Battery Saver for free on Google Play.
Recently we told you about malware inside of Google Play and we also alerted you to the resurrection of Simplocker, a dangerous ransomware that has started its second infection wave. Hopefully, you are convinced that you need to seek a top security application for your Android device. It’s just not safe out there any longer.
However, how can you be sure that our security application is doing its job correctly and extensively?
Some people doubt marketing talk on vendor websites, but we know you cannot start testing every apk file or entering the dark side site of Internet just to see if our solution works. That’s why Avast has chosen to submit our products to third party, independent testing labs.
AV-TEST runs Avast Mobile Security through the paces
AV-TEST is a well-known testing laboratory for mobile security. Recently, they tested 31 mobile security products for Android focusing “on malware detection and usability, including performance and false positives”.
They used 2,950 different malware samples and Avast Mobile Security blocked 100% of them. The malware set was a very recent one: malware in the wild in the last 4 weeks.
Avast Mobile Security did not commit any mistake when tested with 1,932 legitimate apps from the Google Play Store and 981 legitimate apps from third party app stores. The better of the two worlds: protection and usability.
In addition, all this protection, according to AV-TEST, did not “impact the battery life”, or “slow down the device during normal usage”, and “does not generate too much traffic”.
The testing Lab gives a thumbs up for all the other security features that you can find in Avast Mobile Security:
- Anti-Theft for remote lock, wipe and locate your lost or stolen device. NOTE: For those of you who do not have automatic update turned on, please do an update ASAP so you can keep Anti-theft working optimally.
- Call Blocker from specific or unknown numbers and a SMS Filter for unwanted content.
- Safe Browsing that protects against malicious websites and/or phishing.
- Backup for personal data on cloud storage.
- Firewall that allows control over your connection usage over 3G/4G/Wi-Fi/Roaming.
- Network Meter that gives you easy to understand information about your data plans.
Don’t you want to try it? You can download Avast Mobile Security for free on Google Play.
