A SEO specialist needs a smartphone not only for calls, as it is necessary to work with mobile applications, without which the work becomes more difficult. Personally, I use a dozen applications, including Web Money, Yandex Money, TOTP for Epay and a bunch of other stuff. They allow you to make payments when you are away from home, check your email, and track activity on the site. It’s a big problem if viruses start up on a smartphone, because this is how account data, passwords can float away, and the device starts to blunt and kick.
Today I will tell you how to remove viruses, trojans from a smartphone running Android 5. It will take half an hour to clean up, after which you won’t have to worry about the state of the balance of payments, and the device will stop showing miracles of stupidity when surfing the Internet.
The birth of a problem
The problem was born immediately after the New Year, when my son and I tested the capabilities of a new smartphone and downloaded various rubbish from everywhere. The first sign of the disease manifested itself in the refusal to update via OTA, as they were changed by viruses system files. The disease of the device has progressed - when connected to the Internet, the left applications began to load by themselves, such as AliExpress, the processor began to overheat from the effort, and the phone freezes.
As a result, at the end of the first month of life, it became impossible to use the Internet without a mat, launching applications became flour and the phone shone flying into the wall, despite the guarantee.
Virus Scan
Naturally, I did not sit back and began to look for evil spirits on the phone. Antivirus 360 Total for a smartphone disappointed - when checking, it found 6 dangerous files, but did not show their installation location and could only offer to disable applications. He cannot delete anything because of the lack of root rights. The list of dangerous applications included:
- - Android Media Service,
- -App Manager,
- - Guard Service,
- - phone service,
- - Setting service.
In applications, I found only the first two, the rest were successfully disguised. It didn’t make sense to carry a smart under warranty, there was also no desire to pay for flashing a new device. What to do, the eyes asked the brain, the latter strained.
Working solution started with installing Malwarebytes-anti-malware, then went on knurled.
Removal instructions
In order to completely remove all viruses and trojans on Android, three programs were needed:
- Malwarebytes-anti-malware,
- King Root,
- ES conductor.
The Malwarebytes anti-virus scanner found all the viruses, Kingo allowed me to get root-rights for removal, and the Trojan explorer removed.
Malwarebytes
First, install Malwarebytes and scan your smartphone. He will find all the evil spirits, indicate its location on the phone and give brief description viruses. The scanner is compatible with regular antivirus, so you don't need to uninstall anything before installing it. I found it in system / priv-app:
- - org.show.down.update,
- -newmast.apk,
- -higher.apk,
- -newdlir.apk,
- - parlmast.apk,
- - CLPower.apk,
- - smalls.apk,
- - tpings.apk,
- - oneshs.apk.
This is from what he could not remove due to the lack of root rights and morale, he burned 4 folders with malicious content at the stake, I don’t remember their names exactly - the ashes hid everything. Overwrite the "coordinates" of dangerous files that the scanner found but could not delete.
So, after scanning, you found viruses, some of them were removed and you know the exact location of the rest of the malicious files. Now you need to get root rights and install the explorer to delete files.
Kingo Root
On my Android 5, only Kingo Root has successfully become, so I recommend it. Even the vaunted Bajdo Root did not. You will find all the programs needed to remove viruses below. They are personally tested by me, everything is working and will not break Android.
Before installing Kingo, I recommend that you follow two rules - charge your phone normally and connect to the network, as you will need to download updates and install Super User. You launch the application, click "get root" and turn blue while waiting for the software to be installed and updated. There are more hard way installing root rights using Kingo through a computer, but do not complicate your life when it works like that.
ES conductor
Got rights? Now install ES_file_explorer- a conductor capable of working with root rights. In Explorer, go to the menu (top left), look for the Root Explorer tab and turn it on. Agree with stupid questions from the application and go to the menu item " Local storage- device".
It remains to find malicious files and delete them. Select and delete.
After removing the viruses, restart your phone and scan it again with a scanner. If not everything is removed, repeat the procedure for complete recovery.
The disease requires sacrifice, as it happened.
So, let's consolidate the material covered:
- - Install Malwarebytes and look for viruses,
- - Record the location of non-deleted files,
- - Install Kingo Root and open root rights,
- - Install ES Explorer,
- - Remove viruses
- - Reboot your smartphone
- - Recheck the system with a scanner again.
Remove the Kingo Root program immediately after the destruction of viruses, you can leave Super User and ES Explorer. If you are going to the workshop warranty repair and you need to remove root-rights and their traces, then go to the Super User menu and use the "remove root" line. If Super User was removed and you still have root rights that need to be removed, then put it again and remove the rights through the menu. Otherwise, the SU file in system / bin cannot be reached.
And yes, if you think that you don’t have viruses on Android, but in 90% of cases you are wrong.
You can download Malwarebytes, ES Explorer and Kingo Root in one rar file directly from the Zegeberg blog.

The standard media scanner on Android doesn't work well: it constantly goes through the same folders and checks the same files. Real benefit little from him: he only makes sure that the standard player and gallery always have up-to-date files, but he does it with failures. The worst thing is when he bumps into broken file or mistakes file system- then the load on the processor and battery increases greatly.
The enthusiasm with which the media scanner crawls through folders operating system, can be limited. If you know for sure in which folders your photos, videos and music are stored, do nothing with them, but copy an empty file called .nomedia to all others. The presence of this file is a warning to the media scanner that it is not necessary to enter here, there is nothing interesting here. In Android 4.3 and 4.4, the media scanner has learned to ignore the .nomedia file and sometimes scans them.
If the media scanner still appears among the leaders of battery consumption, you will have to resort to more drastic measures - disabling it. For this you can use free app Rescan Media ROOT. It needs root access and activated mode debugging via USB. If all this is there, launch the application and click the "Disable Media Scanner" button. Now it is responsible for scanning and adding media files to libraries, checking is carried out manually, no background scanning that consumes the battery without demand will be performed. The Re-Enable Media Scanner button disables file scanning through Rescan Media and returns the standard media scanner.
Sometimes there is a problem in which the player stopped seeing some of the tracks, and some photos disappeared from the gallery. This means that errors occur during the scan or it is stopped. Need to fix. Open settings and go to the list all installed applications, find "Media Storage" and clear the cache and user data in it.

What is it all about : The MediaServer process in Android is responsible for scanning and detecting media files on the internal memory or memory card.
Solution
:
Most fully disclosed
- MediaServer Android or a solution to the problem of fast battery consumption
- If the Android device is used as an external drive, then always perform a "Safely Remove" from the computer. As mentioned above, the MediaServer Android problem occurs due to file corruption.
- Use a quality microSD card (well, that's understandable)
- Do not defragment flash drives and memory cards - this is certain death for them. (???)
- Fix multimedia files (connect the device as a drive, run the utility to fix errors in MP3 files - then scan and FIX)
- If there are questionable video files on the device - under-downloaded or broken, delete them.
- Add an empty file to the root of the music folder (and to all folders and subfolders with media content) .nomedia then the content would not be indexed, and then always use a player that can scan the folders indicated to it and not use the system library. For example - PowerAMP
- Remove all characters from the names of .mp3 files and their tags, including “unwanted” characters (such as "&" and "_")
- Clear media storage: "Settings > Application manager > All > Media storage > Clear data (+ Clear cache)"
- Change the alarm melody to “basic”, instead of the .mp3 file
- Edit the build.prop file by adding the lines:
pm.sleep_mode=1
ro.ril.disable.power.collapse=0
media.stagefright.enable-player=false
- Use program " Rescan Media ROOT"
- Use program " App to Kill Mediaserver"
- Disable "media storage" via Autostarts
- Use Mediaserver Killer (requires root, doubtful, because if you have root, it's easier to freeze/delete)
- Check media for errors.
- Format the media, after making a backup.
One more recipe
:
I continued to study the problem, and found out that the problem is not in the mediaserver process, but in the so-called “wakelocks” that programs visually present to us “ Wakelock Detector" and " BetterBatteryStats”.
In the morning, the following vicious wakelocks surfaced: AlarmManager(processes Google Maps, Viber, etc.) and Audio_out2(process 1013), which was loaded for 9 hours of statistics, worked for 8.5 (!) Hours. Mr. [email protected]$
.
Quote: " …AudioOut_2… To fix: open settings, select sound. Turn off keyboard sounds, touch sounds, screen lock sounds, and touch vibrations. It's a matter of habit, but the extra battery life you get just by solving this ridiculously simple problem is more than worth it...”
The sounds of pressing and vibration feedback were always turned off for me, but vibration lock screen- No. Here's the reason I've been looking for so long. After turning off the vibration feedback "gone" mediaserver and Audio_out2, and with them the problem of “night zhora”.
