Application administrators cannot remove the check mark. Possible solutions

Twitter

I'm trying to remove the program from device administrators and it doesn't work. That is, I click on the name of the program, select Disable and the phone immediately turns off. After a minute or two it turns on, but the program remains the same as the administrator. This harmful program is a virus, that's why I want to disable it. Because otherwise it will not be deleted.

Install the KIS program from Google Playmarket https://play.google.com/store/apps/details?id=com.kms.free or Malwarebytes Anti-malware https://play.google.com/store/apps/details?id=org.malwarebytes.antimalware
Launch and execute full check phone. This will take a long time, but be sure to wait for it to finish! When the scan is complete, remove the malware found.
Now try again to remove the malware from the device administrators. Open Phone Settings, then Security, then Device Administrators. Uncheck the box next to the malware. Confirm your actions. If a window appears with the message “To roll back updates, a full factory reset is required. All information on your device will be deleted..”, then feel free to click on OK. This message is only meant to scare you.
If step 3 was successful, then open the Applications section in your phone Settings and remove the malicious program.

Hello! I have a similar problem, only after I unchecked the checkbox, the phone began to ask for a PIN code on the main window. Doctor Web remained in the administrators and it looks like that application (called “Installation”, with the Avito icon). The phone works itself, calls, messages come, but I can’t go anywhere. When I restart the phone, sometimes a notification appears that an error has occurred in the Installation application. With or without the SIM, the phone still asks for a PIN code. I installed android in safe mode, all the same..

Tell me what to do? (Android explay ALTO, firmware v1.00)

How to delete an application on Android

Work with modern smartphones, as a rule, is quite simple. This is especially true for applications, namely installation using Google Play and removal through program settings. The situation is different when it comes to preinstalled ones that the smartphone or tablet manufacturer has safely installed. Most often, such software cannot be removed. What to do then?

There can be two reasons for this problem:

How to remove the device administrator program on Android

What is a device administrator? software, which has an extended list of powers and rights, unlike other ordinary applications. To the point that such a program can, if necessary, lock the phone and set passwords. But there is nothing to be afraid of, and you can deactivate it in the special menu “settings - security - device administrators”.

How to remove built-in system applications

Very often you can see how a smartphone manufacturer tries to “take care” of its users and install as many unnecessary and useless programs as possible. And besides, they tend to run in the background and drain the battery faster.

To solve the problem, you need to find the hated program in the settings, press the “Disable” button, clear the data and cache. After this, it will no longer appear in the menu, will not consume RAM and influence the operating time of the smartphone. Delete completely regular means it won't work - we need it root rights. However, be careful when manipulating any system applications, this may affect the entire operation of the smartphone.

How to get rid of uninstallable applications

Installing and uninstalling applications in the operating room Android system- a very simple process, a few touches on the screen and you're done. However, there are applications that refuse to be removed. This situation occurs because some applications are installed as a device administrator, while others are already installed (pre-installed) by the device manufacturer and the user does not have rights to remove them.

For complete removal pre-installed applications root rights will be required. If you don't want to root your device, you can try disabling preinstalled programs, so that they do not run along with Android and do not take up space in RAM. So, how to remove uninstallable applications.

Uninstalling admin apps on Android

Device administrator applications require more rights for their full functionality. This should not be confused with applications that require root rights, it’s just that administrator programs need more rights within the existing user rights. For example, to install protection or remote lock smartphone, tracking it via GPS, etc.

If the application you installed is not uninstalled, then go to the settings of your Android device, go to the “Security” section and then to “Device Administrators”, in which uncheck the program being deleted that it is an administrator.

After this, the application will be uninstalled without any problems.

Removing or disabling pre-installed applications

There are manufacturers who abuse the installation of their programs that cannot be removed. You can delete them, as mentioned above, only by obtaining root rights on the device. But what to do if you don’t want to do this or the smartphone/tablet is under warranty and its root serves as the basis for removal warranty obligations? In this case, you can try stopping pre-installed applications. To do this, do the following:

Disabled pre-installed applications should disappear from the menu and will no longer launch with Android, and also take up RAM, which in budget smartphones will a big plus, where it is always in short supply.

However, with system applications this procedure must be done carefully, because you may encounter unstable work your device.

How to get rid of uninstallable applications?

Purchasing process various applications V Google store Play is incredibly simple. To do this you need to find the desired program or a game, read the description and reviews of other users, after which you can safely click on the “Install” button. Uninstalling apps is no more difficult: it only takes a few clicks. However, from time to time the system refuses to remove certain programs, not to mention applications pre-installed by the manufacturer. How to get rid of this problem? Let's find out.

In general, there are two reasons for not deleting an application. In the case of the first, the annoying program can act as a device administrator. The second option is much more common, and each of us has probably encountered it. We are talking about applications that are part of the smartphone system. In other words, programs preinstalled by the company’s engineers, for which there is simply no delete key.

Possible options solutions to both the problems described above our foreign colleagues from phonearena shared. Let's look at each of them separately.

Administrator application

Don't rush to close this article: There is nothing wrong with this phrase. The fact is that some applications require more extensive permissions. For example, setting a password on a smartphone, blocking it, tracking geolocation and much, much more.

IN in this case To remove them, just uncheck the box in the special section of the menu. In my good old HTC One S, which returned to use after the experience with the iPhone, for this you should go to settings - security - device administrators. One problem is solved, but what about the other?

System application

Not all smartphone manufacturers love their users. The proof of this statement is great amount absolutely useless pre-installed applications that you have no desire to use. In a Taiwanese smartphone, again, similar ones include the EA Games icon, Friend Stream, Rescue, Teeter and other dubious programs.

Agree, it’s not so much their presence that’s annoying as the inability to get rid of them, right? However, it turns out that there was a way out of this situation.

To do this, you need to go to the application manager, select the hated program and find the “Disable” button. Following this, you can also clear the application cache.

The result will not be long in coming: the marked applications will disappear from the menu and will no longer remind you of themselves. However, it is not always possible to get rid of them completely: most likely, some programs will take up several megabytes in the memory card bins, but do not forget about the main advantage. A disabled application will not launch when the device is turned on, thereby saving RAM and, accordingly, device charge. Not bad, right?

Be that as it may, we should not forget that many system applications affect the operation of the smartphone as a whole, and therefore you should experiment with disabling them with extreme caution.

Hello! As I understand it, you know the graphic key itself, you just can’t turn it off. So your situation looks something like this:

You can change your pattern to a password or PIN, but you can't choose the simpler, unsecured options because it's "Disabled by your administrator, encryption policy, or credential store." Usually the problem is that you have some kind of certificate installed on your smartphone, which, according to its internal policy, does not allow you to reduce the security of the phone, that is, disable the unlock password. Please note that if your smartphone is configured work email, remote connection to your organization's network, then this may be your company's security policy. In this case, you should first consult with your IT specialists. If you don’t have anything like that on your phone, the method described below will help you.

How to turn off a graphic key if it is prohibited by the administrator

Go to your phone’s settings and select “Security” -> “Device Administrators”. There shouldn’t be any applications enabled that you don’t recognize; if there are, try turning them off.

Next, the most important thing, scroll to the very bottom and click on the “Cleaning certificates” item. Confirm your action by clicking the "OK" button. After that, go to the shutdown menu graphic key, blocked items should now be accessible. You may have to restart your smartphone.

There is another method, it should be used only if the method above does not help (that is, you have some kind of unique situation) - full reset your smartphone to factory settings (we have detailed instructions). But keep in mind that all data will be lost. How to save them - read our article

The firmware of many smartphones and tablets running Android contains so-called bloatware: applications pre-installed by the manufacturer of dubious usefulness. Typically remove them in the usual way will not work. Therefore, today we want to tell you how to uninstall such programs.

In addition to bloatware, virus software cannot be removed in the usual way: malicious applications use loopholes in the system to pretend to be the administrator of a device for which the uninstallation option is blocked. In some cases, for the same reason, it will not be possible to remove completely harmless and useful program like: she needs administrator rights for some options. System applications like the Google search widget, the standard dialer, or the default one are also protected from uninstallation.

The actual methods for removing uninstallable applications depend on whether your device has root access. It is not required, but with such rights you will be able to get rid of unnecessary system software. Options for devices without root access are somewhat limited, but in this case there is a way out. Let's look at all the methods in more detail.

Method 1: Disable Administrator Rights

Many applications use elevated privileges to control your device, including screen lockers, alarm clocks, some launchers, and often viruses that masquerade as useful software. The program to which access is granted Android administration, you won’t be able to uninstall it in the usual way - if you try to do this, you will see a message stating that uninstallation is impossible due to active options device administrator. What to do in this case? Here's what you need to do.

Make sure that developer options are enabled on your device. Go to "Settings".

Pay attention to the very bottom of the list - such an option should be there. If it is not there, then do the following. At the very bottom of the list there is an item "About the phone". Enter it.

Scroll to "Build number". Tap on it 5-7 times until you see a message about unlocking developer options.

Enable USB debugging mode in the developer settings. To do this, go to "Developer Options".

Activate the options using the switch at the top, then scroll through the list and check the box next to "USB Debugging".

Return to the main settings window and scroll down the list of options to the general block. Tap on an item "Safety".

On Android 8.0 and 8.1 this option is called "Location and Protection".

Next, you should find the device administrators option. On devices with Android version 7.0 and lower, it is called this "Device Administrators".

In Android Oreo this feature is called "Device Administrator Applications" and is located almost at the very bottom of the window. Enter this settings item.

A list of applications that are allowed to additional functions. As a rule, there are inside remote control device payment systems(S Pay, ), customization utilities, advanced alarm clocks and other similar software. There will probably be an application on this list that you can’t remove. To disable administrator privileges for him, tap on his name.

On latest versions OS from Google this the window looks like this:

In Android 7.0 and below - there is a button in the lower right corner "Switch off", which you need to press.

In Android 8.0 and 8.1 - click on "Disable device admin app".

You will automatically return to the previous window. Please note that the check mark next to the program for which you have disabled administrator rights has disappeared.

This means that such a program can be removed in any available way.

This method allows you to get rid of most uninstallable applications, but may not be effective if powerful viruses or bloatware embedded in the firmware.

Method 2: ADB + App Inspector

Difficult, but the most effective method getting rid of uninstallable software without root access. To use it, you will need to download and install it on Android computer Debug Bridge, and on the phone - app Inspector.

Having done this, you can proceed to the procedure described below.

Connect your phone to your computer and install drivers for it, if necessary.
Make sure that the archive with ADB is unpacked to the root system disk. Then open "Command line": call "Start" and type the letters in the search field cmd. Click on the shortcut right click mouse and select "Run as administrator".

In the window "Command line" write the commands sequentially:
cd c:/adb
adb devices
adb shell

Go to the phone. Open App Inspector. A list of all applications available on your phone or tablet will be presented. alphabetical order. Find the one you want to delete among them and tap on its name.

Take a close look at the line "Package Name"— we will need the information recorded in it later.

Go back to your computer and "Command line". Type the following command in it:
pm uninstall -k --user 0 *Package Name*

Instead of *Package Name*, enter the information from the corresponding line from the page of the application to be removed in the App Inspector. Make sure the command is entered correctly and press Enter.
After the procedure, disconnect the device from the computer. The application will be deleted.

The only drawback of this method is that it removes the application only for the default user (the “user 0” operator in the command given in the instructions). On the other hand, this is a plus: if you deleted a system application and encountered problems with the device, it’s enough to simply do this to return the deleted one to its place.

Method 3: Titanium Backup (Root only)

If your device is rooted, the procedure for uninstalling uninstallable programs is greatly simplified: just install Titanium Backup, an advanced application manager that can remove almost any software, on your phone.

This method is the simplest and convenient solution problems with uninstalling programs on Android. The only problem - free version Titanium Backup is somewhat limited in its capabilities, which, however, are sufficient for the procedure described above.

Conclusion

As you can see, uninstallable applications are quite easy to deal with. Finally, we remind you - do not install dubious software on your phone from unknown sources, because you risk running into a virus.

Usually, deleting files and folders is quick and painless, except for the warnings Windows messages, which are protection against accidental pressing buttons. But in some cases, the system refuses to perform an action, citing the impossibility of executing the command. It's time to figure out the reasons for such errors.

In what cases may it be necessary to delete “undeletable” folders or files?

Windows 7 may refuse to delete files or folders for several reasons:

damage. Physical or software failure, virus operation;
usage. The file is used by a running application or the system itself;
lack of rights. The user account does not have sufficient permissions to delete.

Possible solutions

If the matter is software glitch, it may be sufficient to restart the computer.
When using a file in another application, you need to determine which program is using it and close it. In some cases, it is also necessary to contact the “Dispatcher Windows tasks", to stop background processes, for example, torrent clients.
Sometimes the system refuses to delete even outwardly empty folders. This may be due to the Explorer settings do not show hidden files. In other words, the folders only appear empty; they contain information that is hidden from the user. Therefore, you should first make sure that these directories really do not contain information. Otherwise, you can unintentionally erase important data and disrupt the stability of the system.
If files and folders are visible, but they are not deleted due to the lack of rights of the account under which the system was logged in, you can do one of the following:
- use another entry. Restarting the system as a user with administrative rights is the easiest and most painless option. In this case, the OS settings do not change, and after carrying out all the necessary manipulations, you can return to the previous account;
- get your license. You can increase the level of rights of the current account. However, this method reduces the computer’s security not only from careless user actions, but also from malware. The virus will cause much more damage to the PC if it entered as an administrator;
- turn to third-party applications. There are utilities that specialize in forcibly deleting information, including protected information.

Uninstall by granting administrator rights

A user with normal rights can create, delete, and modify most files and folders, but does not have modification access system information, which serves to protect against unintentional and careless actions. The administrator account has no restrictions, within which you can regulate the operation of the entire system.

The best solution is to use the two entries alternately. User - for everyday work, administrator - for setting up the system.

Only an administrator can grant superuser rights to a regular account. Therefore, the following methods are only suitable if such an opportunity exists.

Through system settings

Press the Win key or the on-screen Start button. IN search bar, located at the very bottom of the list that opens, enter the request “User Accounts”.
We go to the active line located at the top of the list of search results and open a window with the heading “Making changes to account user". Click on “Manage another account” in the central part.
By clicking on the tab, we will be taken to a window with a list of all accounts created by the system. We select the one to which we want to give administrative rights and change its type to “Administrator”.
Click on the “Change account type” button. Rights granted.

Via command line

Usage command line requires some experience, but allows you to perform many operations faster. In order to call desired window, let's use the search bar again.

Disabling TrustedInstaller

In fact, Windows 7 has a user with even greater rights than any administrator. To protect critical components, the system creates a TrustedInstaller account, which is assigned exclusive access rights to certain files.

If a user, even with administrative rights, tries to delete protected information, the system will refuse him and show a window with the message: “Request permission from TrustedInstaller to change this file.”

To bypass the protection, you must manually grant access to the desired file to administrators, after which you will be able to delete it.

In Explorer, select the file that you want to delete and right-click on it.
In the context menu that opens, select “Properties”.
Then go to the “Security” tab.
Click on the “Advanced” button.
In the window " Extra options Security" go to the "Owner" tab.
Click the “Change” on-screen button.
Windows 7 will offer several options to change the owner of a file. Immediately select the “Administrators” group and click “OK”.
We read the message that appears recognizing our rights and describing necessary actions for them to take effect, then click “OK”.
We repeat previous actions. We need to clarify our powers.
Click the “Change” button and select the added “Administrators” group.
We put a mark on “ Full access”, automatically receiving notes on all other items.
Click the “Apply” button, giving everyone accounts with administrative rights the ability to edit this file.

The same mechanism can be used to edit or move important files or folders. In this case, it is necessary to return all settings to their original state after completion of work, otherwise Windows case 7 may become unstable.

By editing the Startup list

Can prevent file deletion executable application. If it is launched deliberately, it is enough to shut it down, and in some cases it is also useful to restart the computer. But programs that automatically start when Windows startup 7, will again end up in RAM and prevent you from deleting necessary information. Therefore, you need to exclude them from the Startup list.

If we have correctly identified the application that is interfering with our task, the file will be deleted without problems. If another program interfered, you can repeat the process for it or use reboot Windows in safe mode.

Via Safe Mode

If a folder or file is not deleted due to work third party application or malware, you can restart your computer in safe mode and thereby bypass the ban.

Safe mode in Windows 7 involves minimal loading of system components.

The advantage of this method is that there is no need to leave Windows shell 7. The disadvantages include the fact that to reboot in normal mode you will have to repeat the same steps, only this time disable safe mode.

In order to boot the system once in safe mode, you can use another method.

Having loaded using any of the listed methods, we find “stubborn” files using “Explorer” and delete them.

Using the command line

You can bypass the deletion ban using a low-level tool that is already a little familiar to us - the command line.

After the window loads, you must enter the required command.

Commands for forcibly deleting root directories and files - table

When using the command line to delete files or directories, keep the following in mind:

The information is erased irrevocably, that is, it cannot be restored from the Recycle Bin.
It is necessary to accurately, without errors and completely enter the name of the files to be deleted, including the extension and full path.

Through file managers

Most file managers have built-in capabilities for deleting protected files and folders.

For example, when working with a popular file manager Total Commander To delete a file, just select it and click function key F8. The application will definitely clarify whether the user is confident in his actions.

Total Commander easily copes with most protected files and folders, limiting itself to just one more request to the user. But some information is beyond his capabilities, in which case it is better to use specialized applications.

Removal using third-party programs

If the need to delete protected files and folders arises regularly, it makes sense to install on your computer one of the applications that specialize in unlocking and destroying information.

Unlocker

Simple and convenient program Unlocker is automatically added to context menu, which opens when you right-click on the file name.

An additional advantage of the application is the ability to see why a file is blocked and what process is using it.

It is likely that it is not at all necessary to use a “hard” removal; sometimes it is better to return to Windows 7, close the interfering program, and then erase the unlocked file. But you can do without this by simply selecting the “Delete” option.

The lock prevents not only deleting, but also simple operations such as moving a file or renaming it. Unlocker can help with this too.

Lockhunter

Another application with similar functionality is Lockhunter. This utility is even built into the Explorer context menu and can delete those files and folders that Unlocker cannot do.

The program interface is more like classic Windows, basic information is collected in one window, and the main operations are presented in the form of large buttons.

Although Lockhunter does not support the Russian language, the simplicity of the interface and free distribution make it very popular.

The program's wide capabilities can become a serious problem if used carelessly. Lockhunter can easily remove system files, thereby disrupting the performance of Windows 7.

Job Fileassassin programs built in a slightly different style:

Using multiple special utilities with similar functionality can be justified by the fact that they have various algorithms work. Files that one program could not delete can be erased by another.

System Restore

The system “rollback” mechanism using backup points is a universal means of recovery Windows performance 7 in case of serious failures.

The system restores its “old” state by erasing additionally installed programs and settings, so as a last resort, you can use this radical remedy for those files and folders that cannot be erased.

A prerequisite for this method is the availability of suitable backup recovery points. It should be taken into account that some malware intentionally corrupts such files, so it is better to transfer such data to external media.

Launch the recovery utility. To do this, type “System Restore” in the search bar and press Enter.
The window that appears is more informational than functional, so click the “Next” on-screen button.
Select the one you need from the list of recovery points and click “Next”.
Don't forget to save your working files to external media before restoring your system, otherwise they may be lost.
Once again, we make sure that this is the date to which we want to “downgrade” Windows 7, and click the “Finish” on-screen button.

Using a different operating system

All restrictions and access settings are important only when running a specific copy of Windows 7. From an external point of view, both the system itself and the files carefully protected by it are ordinary records on the hard drive. Therefore, all unnecessary information can be deleted by gaining access to the drive without starting the “main” Windows 7:

By downloading another copy of Windows 7 located on the second physical disk.
Launching another operating system eg Linux.
Using a bootable USB flash drive or “life disk”.
Physically taking it out HDD and connecting it as external media to another computer.

This method will also be useful in combating some particularly stubborn viruses that penetrate RAM and block antivirus programs. By booting from external media, you can disinfect your computer without letting malicious applications start work.

If you don't have your own bootable flash drive, it can be downloaded from the developer sites antivirus programs, for example, DrWeb or Nod 32.

The disadvantages of this method are a consequence of its effectiveness - it can be accidentally removed critically important files and folders, disrupting Windows.

other methods

If the information that refuses to be deleted is located on an external storage device (SD card, flash drive or external hard drive), then you can solve the problem using a device with a mobile operating system, for example, Android. Some nuances:

The SD card can be inserted into the appropriate slot on your smartphone or tablet.
To connect a flash drive you need support for OTG technology and a suitable adapter.
To work with external hard drives devices on Android based usually needs to be downloaded additional applications, and also ensure a sufficient level of current to power the drive.

Before looking for ways to delete system-protected information, you should make sure that such a step will not harm the performance of Windows 7. It may be worth creating an additional restore point to minimize the negative consequences.

In addition, you should first use the most safe ways and only if they are ineffective, move on to more “rough” ones:

User Tools. Find and disable programs and processes that use necessary files. Restart your PC.
Windows Tools. Edit the Startup list, use safe startup mode if necessary.
Access settings. Gain administrative rights or access to account files.
Command line. Use system commands for low level removal.
Third party applications. Use file managers or specialized programs.
System Restore. Use backup point recovery for "rolling back" Windows 7.
External OS. Boot the operating system from external media or another computer.

How to delete protected folders and files without additional programs - video

System-based means of protecting critical information are often used malware for your own purposes, so you need to be able to bypass restrictions and delete damaged files. Fortunately, enough has been created for these purposes effective applications, including free ones.
