How to remove a trojan bootloader from android. How to remove Trojan with Android - a few useful tips. We remove the Trojan with the help of special antivirus programs

No matter how the users have swore on the fact that the Android operating system is vulnerable to various kinds of viruses, the main cause of infection is the illiteracy of the person himself. How does the threat fall into the phone or tablet? For example, the user wanted to download the broken version of the paid game. Similar manipulation in 80% of cases threatens a virus infection. Another common situation: Comes a message in any social network citing. Few people will keep the temptation to go through it. At this stage, the threat is penetrating directly to the phone. About what to do and how to protect yourself from a similar situation, let's talk in this article.

Fake

Often the virus on the "Android" can be hidden under completely harmless applications: browsers, navigators, games, players, books and, most interesting, antivirus.

Distinguish two types of threats. One of them is called "fake." He got his name is not by chance. Such a component looks like a well-known application, and have a malicious code. Such a program (viruses on Android can be masked under the favorite Vkontakte, Odnoklassniki and so on) when opening, begins to actively act.

"Trojan horse"

The second type of threats received a generalizing name - " trojan horse" Such viruses are more harmful, they are difficult to calculate, respectively, it is practically unrealistic to remove if the user is new to the newcomer. They are embedded at any frequently running application on the phone or tablet, changing its source code.

We will talk about ways to remove such threats below, but you need to know that most of them are located in the "Download" folder.

Than

The virus on the "Android" can make many actions. Most popular Consider below.


How to distinguish a "healthy" application from viral?

The overwhelming part of the viruses that quickly and without problems are set on the devices are written by non-professional programmers. They are needed for easy money earnings. That is why it is quite simple to calculate such threats - it's enough to look at the list of permissions of the application being installed. As soon as this virus is on "Android" (on the phone or tablet), and the consumer activates it in the system, it will immediately start sending messages to paid numbers or call them.

Not all applications work in this way. However, these are the most common and, by the way, easily eliminated.

What to pay attention to the installation of applications with third-party resources? The first bell is if the program makes incomprehensible requests for:

  • access to the camera means the developer wanted to shoot something;
  • access to memory and Internet connection - files are needed from the phone;
  • administrator rights are needed to advertise.

The qualitative virus on the "Android" is more difficult to identify. But it is necessary to alert if the application has been downloaded from an incomprehensible resource and requests the rights to carry out paid functions - such a software by 99% is a virus.

How if there is access to the menu?

Publicly available and one of the most simple waysHow to get rid of viruses is described in this section. If the consumer realized that in his phone or tablet "settled" the threat, it is worth making active actions:

  1. First you need to immediately remove the SIM card. Such a step will help secure the account of the owner from unpredictable spending.
  2. After that, Wi-Fi should download any antivirus. It is impossible to recommend any special, since most of the famous defenders is updated every time, so they are all highly efficient. The most popular - "Dr. VEB", "Kaspersky".
  3. You must run a detailed check and remove all existing threats.
  4. After the entire procedure, antivirus should be eliminated.
  5. You need to download the second antivirus. The first must be removed for the reason that sometimes two similar applications can not work simultaneously on one device.
  6. After checking the instrument and delete all suspicious programs, it is necessary to disable administrator access to the administrator's rights. If suddenly some of the programs do not give it to do (which is already forcesing to think), you need to boost the device in safe mode And make this manipulation of it.
  7. After that you need to go to installed applications And remove those that are not familiar to the owner.
  8. The last step is to restart the device.

The same to whom did not help the above method, one can recommend to make a discharge of settings to factory. As a rule, it erases all viruses that have been installed. But this option will not be useful for components embedded in the system itself. So, the easiest way to remove the virus from the "Android" phone is already described in detail and can help most of consumers. If nevertheless, it was not possible to solve the problem independently, then one thing remains to contact the service center.

How to fix the virus from the phone or tablet if there is no access to the menu?

As a rule, there is no access to the menu if the screen is "captured" by the banner requiring the phone number account or bank card. What to do in this situation?

Attention! In no case do not need to list the money on the specified details. Fraudsters do not unlock the phone.

  1. The first thing you need to do is remove the SIM card from the device. Otherwise, the virus may empty it in a short time.
  2. You should upload the phone in safe mode. You do not need to worry: the banner in this case will not appear, as only the basic applications necessary for the operation of the operating system will work.
  3. You should go to the menu and disable administrator rights from all programs.
  4. You must delete unknown applications.
  5. Next, you should restart the device.

If it did not help standard fashion Resetting the settings will be quite a reasonable solution.

Change firmware

The question of how to remove the virus from Android, which deeply "sewn" into the firmware is interested in many people. Consider several effective ways.

Immediately need to say that the banal reset of settings will not help. Similar viruses are embedded in operating system And they receive root-rights, which (according to the standard) does not even have the user himself.

The most effective and, perhaps, the simplest for experienced owners is the change of firmware. If you are concerned about the safety of all files that are available on the device, you can always make a "backup". However, some devices have a similar function in common accessOthers require administrator rights for this. The firmware is best downloaded from the official resource. If there is a desire, you can install any other, not necessarily the one that is the factory. It is enough to use the search engine and find the desired version for your phone.

This information will allow you to maintain the phone in working condition even during the infection of viral software. Also, timely removal of the virus will protect user files from infection.

Thematic video:

The sechant smartphone is needed not only for calls, as it is necessary to work with mobile applications, without which the work is complicated. Personally, I use dozen applications, among which Web Money, Yandex Money, TOTP for EEY and also a lot of all. They allow you to make payments outside the home, check mail and track activity on the site. Big trouble, if viruses started on the smartphone, because these accumulation data, passwords can be saved, and the device begins to blend and jerk.

Today I will tell you how to remove viruses, trojans from a smartphone running Android 5. The time for cleaning will leave half an hour, after which the state of the payment balance can not be worn, and the device will stop showing the wonders of stupidity when surfing on the Internet.

Birth problem

The problem was born immediately after the New Year, when I and Son I checked the possibilities of a new smartphone and shook at him a different trash from everywhere. The first sign of the disease manifested itself in refusing to be updated by OTA, as system files were changed by viruses. Device disease progressed - when connected to the Internet, left applications themselves began to load, such as Aliexpress, the processor from Natuga began to overheat, and the phone hang.

As a result, on the outcome of the first month of life, the Internet without Mata has become impossible, the launch of applications has become flour and the phone has shone the flight into the wall, despite the warranty.

Search for viruses

Naturally, I did not sit back and began to look for evil on the phone. Antivirus 360 Total for the smartphone disappointed - when checking, he found 6 dangerous files, but did not show the location of their installation and could only offer to disable the applications. It can not remove anything due to the lack of root rights. The list of dangerous applications turned out to be:

  1. - Android MEDIA SERVICE,
  2. - App Manager,
  3. - GUARD SERVICE,
  4. - Phone Service,
  5. - SETTING SERVICE.

In the applications, I found only the first two, the rest were successfully masked. It didn't make sense to bear a smart manranty, it was also no desire to pay for refressing a new device. What to do, they asked the eyes of the brain, the latter strained.

Working the decision began with the installation of MalwareBytes-Anti-Malware, Further went on the rolled.

Instructions for removal

In order to completely remove all viruses and Trojans on Android needed three programs:

  1. MalwareBytes-Anti-Malware,
  2. Kingo Root.,
  3. ES conductor.

MalwareBytes anti-virus scanner found all viruses, Kingo allowed to get root rights to remove, and the conductor Trojan deleted.

Malwarebytes.

To get started, install Malwarebytes and scan smartphone. He will find all the evil spirits, will indicate its location in the phone and give brief description viruses. The scanner is compatible with the usual antivirus, so it is not necessary to remove anything before installing it. He found me in the System / Priv-App:

  1. - org.show.down.update,
  2. - NEWMAST.APK,
  3. - Higher.apk,
  4. - newdlir.apk,
  5. - Parlmast.apk,
  6. - Clpower.apk,
  7. - Smalls.apk,
  8. - Tpings.apk,
  9. - ONESHS.APK.

This is from the fact that he could not delete due to the absence of root-rights and moral sensation, 4 folders with malicious content he burned on a fire, I just don't remember their name - I hid everything. Rewrite the "coordinates" of dangerous files that the scanner found, but could not delete.

So, after scanning, you found viruses, some of them deleted and know the exact location of the remaining malicious files. Now you need to get root rights and install a conductor to delete files.

Kingo Root.

On my Android 5 successfully became only Kingo Root, so I recommend it. Even the squeezed Bajdo root did not. All programs needed to remove viruses, you will find below. They are verified by me personally, all working and will not break android.

Before installing Kingo, I recommend complying with two rules - normally charge the phone and connect to the network, as you need to download updates and installing Super User. Run the application, click "Get Root" and shine waiting until the software is installed and updated. There is a more complex way to install root-rights with using Kingo. Through the computer, but you should not complicate my life when it works and so.

ES conductor

Did you get right? Now install ES_File_Explorer - Explorer capable of working with root-rights. In the Explorer, go to the menu (left top), look for the root-conductor tab and turn it on. Agree with stupid issues from the application and go to the menu item "Local Storage - Device".

It remains to find malicious files and remove them. We allocate and delete.

After removing viruses, reboot the phone and scan it once again with a scanner. If not all deleted, repeat the procedure for complete recovery.

The disease requires the victims, it was so heard.

So, fasten the material passed:

  1. - Install MalwareBytes and look for viruses,
  2. - write down the location of not deleted files,
  3. - Install Kingo Root and open the root right,
  4. - Install ES conductor,
  5. - remove viruses,
  6. - Restart the smartphone,
  7. - Recheck the scanner system again.

Delete the Kingo Root program immediately after the destruction of viruses, Super User and ES Explorer can leave. If you make a warranty repair workshop and need to remove root rights and their traces, then go to the Super User menu and use the string " remove root." If Super User has been removed, and you have the right rut rights that need to be removed, then put it again and delete the right through the menu. Otherwise, the SU file in System / Bin can not be reached.

And yes, if you think that you have no android viruses, but in 90% of cases you are mistaken.

Download in one rar file MalwareBytes, ES Explorer and Kingo Root can be directly from the Zegeberg blog.
