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.
How 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.
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 Anti-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.
Have fun checking out Avast Mobile Security’s cool and handy Anti-Theft features, but, please, use caution when testing the siren
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
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!
The 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.
From governments to thieves to your wife – it seems that everyone has access to your private data.
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.
- 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. 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. 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. 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. Do not take, send, save or share nude photos. No, this is not a moral commandment. It’s a privacy one. Read more…
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!

“We’ve now made the avast! Mobile Security product even better, and continue to keep the solution totally free,” commented Vince Steckler, CEO of AVAST Software.
The RSA Conference – the largest gathering of security vendors and the companies who buy their products – was held in San Francisco last month. Avast was in attendance, and I had the pleasure of moderating a panel on mobile security. Mobile security was also one of the top topics permeating the entire event. What I heard on the panel and throughout the conference, and what has been reinforced from my discussions with analysts and consultants to businesses, should have you all pretty worried.
The good news is that businesses want to embrace employees use of mobile phones and tablets. And it’s not just the biggest companies doing so: even small businesses are eager adopters of mobile technologies. After all, employees are more accessible and more productive when they can use their mobile devices for work. However, these are your devices; they are not the company’s and shouldn’t be treated as such. And that’s the challenge.
Businesses have legitimate concerns that these devices are inherently insecure, and that consumers don’t always secure their devices to the same level businesses do their PCs. They are also concerned about all the corporate data that these devices contain or can access, and that their loss or theft can compromise a company. And they are concerned that people will misuse their access to this data now that it’s on their person device.
The problem is that businesses want more security and control over your phone then they should have or even need: even more control than they have over the PCs they provide you.
- Because there are malicious apps, they want to keep a catalog of every app you install and be able to remove those applications without prior notice to you.
- Because mobile devices can hold private corporate data, they want the ability to wipe all data on your phone, also without prior notice to you.
- Because you could potentially misuse the phone by transferring corporate data between a business app (like email) and a personal app (like Facebook), they want to be able to monitor everything you do on that phone: your call logs, your text messages, all your social networking activity, all your browsing activity.
This blatant company disregard for employees’ privacy and property all in the name of security has gotten completely out of hand. One product that was given prominent attention at the conference basically rooted your device to put a monitoring and management layer underneath the operating system. Besides taking any semblance of control of your device away from you, this procedure would likely lead to voiding the warranty for many of your devices, especially Apple devices.
Using your mobile devices for work purposes should not require you giving up all your privacy rights or giving your company effective ownership of your device, without having to pay for it. If your company is letting you use your phone or tablet for work purposes, especially if it’s for more than email, then you should take a close look at your organization’s mobile policies – not just for what you should or should not be doing, but for what your company could be doing.
