5 questions with: Tomáš Heřmanský (Product Manager)

Tomáš Heřmanský

Tomáš joined Avast in March 2014 as a Product Manager for Avast Mobile Security. Born in Čáslav, a small town in central Bohemia, he moved to Prague during high school with plans to study at the Police Academy of the Czech Republic. After a while, Tom decided he wanted to study and work in IT instead. After gaining experience while working at a successful Czech startup, taking on jobs as a freelancer and starting his own company focused on cloud document management, Tom joined Avast’s mobile team. In his free time, Tom enjoys climbing, cycling, writing and restoring his classic Škoda 1000 MB car.


 

1. What is Avast’s mobile team out to accomplish?

We’d like to become the most trusted mobile tools developer, allowing users to live their lives with their mobile devices safely and more easily.

2. Who or what helps you in coming up with new, creative ideas?

My colleagues are a huge inspiration to me. That’s one thing that I really enjoy about working at Avast – anyone and everyone can come up with new ideas to brainstorm. We are one big think tank. :)

3. What’s one thing that every user should know about his/her mobile device?

Users should be aware of the risks that mobile malware poses to their personal information and data. Although malware on mobile devices is less likely to break a user’s device than that of a PC, malicious apps can harvest and steal a lot of personal data. Even apps that aren’t malicious (often free apps) can access a lot of personal information. The more personal info that is shared, the more likely it is that a user’s privacy could become compromised.

4. What’s your favorite security tip?

Make sure to be careful when connecting to public Wi-Fi networks. Packet sniffing, or the monitoring of data traveling over a network, can be used to steal information and is very easy for hackers to carry out. It’s in your best interest to use a virtual private network (VPN) when connecting to unsecured networks.

5. Name one goal you’ve set for yourself at Avast.

I’d like to see Avast Mobile Security (AMS) become the most popular app that provides users with a straightforward, user-friendly overview of app permissions. AMS is an extremely versatile app with lots of potential, and I envision it serving as a true “guarding angel” for users, protecting them against mobile malware and allowing them to become familiar with the apps they use on a daily basis.


 

Avast’s mobile team recently held the second Avast Mobile Internal Conference (AMIC) in Prague, where the entire team came together to keep one another in the loop about the company’s apps and products, team activities, and goals for the department’s future. A series of lectures and interactive activities encouraged synergy and collaboration between product teams. In addition to everything that was accomplished at AMIC, the mobile team still managed to have quite a bit of fun at the conference. We’d like to congratulate the mobile department on this successful and productive event!

Avast Battery Saver raises the bar with new Wi-Fi-based smart profiles

Avast Battery Saver increases battery life by an average of 7 hours.

Avast Battery Saver increases battery life by an average of 7 hours.

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.

Avast Launches Memory Saving Cleaner App for Android

Today, Avast announced the launch of Avast GrimeFighter at the Mobile World Congress in Barcelona. The new application helps Android users free extra memory on their devices with just a few taps so they can save the data that matters to them while enjoying a faster, smoother performance on their devices. 

GrimeFighterHow Avast GrimeFighter works

Avast GrimeFighter begins by scanning all applications on an Android device, identifying unimportant or unnecessary data that could be eliminated without damaging applications’ functionalities. Using GrimeFighter’s easy-to-use interface, users can choose from two modes that allow them to eliminate excess files with ease: Safe Cleaner and Advanced Cleaner. Safe Cleaner is a customizable scanner that quickly identifies unimportant data for instant, one-tap removal. Advanced Cleaner runs in parallel to Safe Cleaner, mapping all of the device’s storage and creating a simple overview of all files and applications that take up space. Advanced Cleaner locates inflated or unused applications and arranges them by file type, size, usage, or name, so users can permanently remove the files and free up storage space.

In addition to cleaning up unwanted data, Avast GrimeFighter helps maximize storage capacity by syncing with personal cloud storage accounts so users can manage their device’s storage without having to delete valuable data. Users can drag files to the cloud icon and GrimeFighter will instantly transfer them to a safe folder in the cloud. Avast GrimeFighter is currently compatible with Dropbox and can assist users in setting up a Dropbox account. Additional popular cloud storage solutions will be added soon.

How does excess data get accumulated?

Bits and pieces of data accumulate on your device, whether you are aware of it or not. GrimeFighter helps you locate excess data that you wouldn’t typically be able to find, such as data left over from initiated app downloads, residual data, thumbnails, and app caches. Popular apps, like Facebook and Instagram, also create excess data on your device as they inflate from their original download size when used regularly. Avast tested some of the most popular Android apps and found that their size can grow exponentially during one week of heavy usage:

                                                                         install size:          additional data accumulated:

1)    Facebook                      36.7MB                        153MB

2)    Flipboard                    12.6MB                        71.1MB

3)    Google Maps            23.21MB                       68.8MB

Avast GrimeFighter will help the more than one billion Android users free up anywhere from 500MB to 1GB of storage per device to enjoy faster performance and is available for download on Google Play.

How to turn off Avast Mobile Security’s Anti-Theft Siren

Avast Mobile Security includes many handy anti-theft features that can help you locate your stolen or lost phone. You can wipe it remotely, it informs you if your SIM card has been stolen, and even allows you take pictures of the person who took your phone. Another cool feature of Avast Anti-Theft is the siren. I decided to test the siren with my friend, who had just downloaded Avast Mobile Security, to see how it could affect a phone thief.

 What does the Avast Anti-Theft siren do?

The Avast AScreen Shot 2015-01-27 at 11.49.44nti-Theft siren was developed by the Avast mobile team to be activated when you either lose your phone (even if it is misplaced in your room and on silent) or if it gets stolen. The siren continuously and loudly says the following, by default, when activated: “This device has been lost or stolen!”. In the advanced settings of Avast Mobile Security you can customize what message the siren will sound, if you do not want to use the pre-set message. You can do this under “Select Sound File” or “Record Siren Sound”.

The siren is designed to frighten phone thieves, or to warn people surrounding the thief that the phone might be in the hands of the wrong person. When the first siren cycle began, we tried to turn down the volume. However, the alarm would begin again at the loudest possible volume. We then decided to see what would happen if we took out the battery, this stopped the siren of course, but as soon as we put the battery back in, the siren started to go off again. To say the least, we agreed that it would effectively frustrate and annoy a thief too.

How to turn off the siren

After a minute of testing the app, we decided to turn off the siren using one of these two possible methods:

MyAvast: You can control your phone remotely via your MyAvast account. In your MyAvast account you can keep track of all your devices that have Avast products installed on them. From within your MyAvast account you send numerous Anti-Theft commands to your phone, including activating and deactivating the Anti-Theft siren. Once you are logged into your MyAvast account click on the name of the mobile device you want to control and then click on the siren symbol. From there you can send a command to turn the siren on and off.

SMS command: Using the Avast PIN you set up when you downloaded Avast Mobile Security, you can send SMS commands to your phone to remotely control it. To turn the siren off, text your Avast PIN followed by “SIREN OFF” to your phone.

Screen Shot 2015-01-27 at 11.46.02

You can read more about how to set up your smartphone for remote control here on our blog and you can find a full list of the Anti-Theft controls on our website.

Have fun checking out Avast Mobile Security’s cool and handy Anti-Theft features, but, please, use caution when testing the siren :)

Apps on Google Play Pose As Games and Infect Millions of Users with Adware

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.

Durak App Google Play The Durak card game app was the most widespread of the malicious apps with 5 – 10 million installations according to Google Play.

Durak interface
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? :)

Threats detected malcious appsEach 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

SimpLocker does what its name suggests: Simply locks your phone!

A new Android mobile Trojan called SimpLocker has emerged from a rather shady Russian forum, encrypting files for ransom. AVAST detects the Trojan as Android:Simplocker, avast! Mobile Security and avast! Mobile Premium users can breathe a sigh of relief; we protect from it!

malware, mobile malware, Trojan, SimplockerThe Trojan was discovered on an underground Russian forum by security researchers at ESET. The Trojan is disguised as an app suitable for adults only. Once downloaded, the Trojan scans the device’s SD card for images, documents and videos, encrypting them using Advanced Encryption Standard (AES). The Trojan then displays a message in Russian, warning the victim that their phone has been locked, and accusing the victim of having viewed and downloaded child pornography. The Trojan demands a $21 ransom be paid in Ukrainian currency within 24 hours, claiming it will delete all the files it has encrypted if it does not receive the ransom. Nikolaos Chrysaidos, Android Malware Analyst at AVAST, found that the malware will not delete any of the encrypted files, because it doesn’t have the functionality to do so. Targets cannot escape the message unless they deposit the ransom at a payment kiosk using MoneXy. If the ransom is paid the malware waits for a command from its command and control server (C&C) to decrypt the files.

What can we learn from this?

Although this Trojan only targets a specific region and is not available on the Google Play Store, it should not be taken lightly. This is just the beginning of mobile malware, and is thought to be a proof-of-concept. Mobile ransomware especially is predicted to become more and more popular. Once malware writers have more practice, see that they can get easy money from methods like this, they will become very greedy and sneaky.

We can only speculate about methods they will come up with to eventually get their malicious apps onto official markets, such as Google Play, or even take more advantage of alternative outlets such as mobile browsers and email attachments. It is therefore imperative that people download antivirus protection for their smartphones and tablets. Mobile devices contain massive amounts of valuable data and are therefore a major target. 

Ransomware can be an effective method for criminals to exploit vulnerable mobile users, many of which don’t back up their data. Just as in ransomware targeting PCs, this makes the threat of losing sentimental data, such as photos of family and friends or official documents, immense.

Don’t give cybercriminals a chance. Protect yourself by downloading avast! Mobile Security for FREE.

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!

The best just got better

A Google alert just popped up this review from Android Authority titled:  “The best just got better“. And I just love the writeup from the author Simon Hill…

“After trying a number of Android security apps and comparing their performance in independent tests it is easy to recommend Avast Mobile Security as your best option. The sheer variety of features is more in keeping with a premium app, but it is still completely free.”

So if you have an Android phone – and according to the latest data by Gartner there should be about 450 million of you out there – go to Google Play and get the best rated security app.  For free.

I’m still having my old Nokia but I guess time has come to get the shiny Galaxy S3 and install as well  ;)
