Sfc/scannow is useless during infections, since the infection blocks the restoration of system files, showing that everything is OK.

But standalone antiviruses will be able to identify the infection if it is in their databases.

But they do not fix system damage.

Therefore, after they have found and deleted something, they need to use sfc/scannow.

Try Kaspersky and Windows Defender Offline, separately, links and instructions, which I publish:

What is Windows Defender Offline?

Sometimes malware and other unwanted programs, including rootkits, try to install themselves on your computer. This may happen when you are connected to the Internet or when installing some programs from a CD, DVD, or other media. On your computer, this software may start immediately or unexpectedly. Offline Defender can help you remove hard-to-find malware and unwanted software by using definitions that recognize threats. Definitions are files that are an encyclopedia of potential software threats. Because new threats emerge every day, Offline Defender must keep up to date with the latest definitions. Definition files enable Defender Offline to identify malware and unwanted software and notify you of risks.

To use Defender Offline, you need to follow the four basic steps below.

Very often, users do not understand how to use Windows Defender Offline and launch it after loading the operating system.

But, the methods of using it are similar to the methods of using Kaspersky Rescue Disk 10.

How to burn Kaspersky Rescue Disk 10 to CD/DVD and boot your computer from it

(step-by-step instructions with screenshots, downloadable files there)

I hope these instructions will help inexperienced users avoid making the mistake of using Windows Defender Offline incorrectly.

And correctly follow the instructions below for Windows Defender Offline:

How do I start my computer from a CD, DVD, or USB flash drive?

It may also be that the definition for this infection is not yet in the anti-virus databases.

Then the only thing that helps is reinstalling the system, clean, for the boxed version, and to factory settings, for the OEM version.

Don’t look for God, not in a stone, not in a temple - look for God inside yourself. Let the seeker find.

Question from a user

Hello.

I had different documents and folders on my flash drive. After reinstalling the system, I don’t find any files on the flash drive, they have now become invisible (although they take up space on it, I see it in the disk properties).

How to restore them, why could they become invisible...?

Hello.

Hmm, some of the most basic reasons for this problem: a virus infection of a flash drive (or your PC), a failure in the file system of the flash drive (although Windows usually offers to check the drive for errors), for some reason the attributes of files and folders have been changed to “hidden” (and Explorer does not show them by default).

Actually, in the article I will look at how to solve this problem...

What to do with the "invisibility" of files

1) Turn on the display of hidden files

How to do it:

By the way, you can also open File Explorer settings using the Windows Control Panel: switch the display to “small icons” and select “Explorer Options”. See example below.

2) Selecting an alternative to Explorer (Far Manager)

In general, I would recommend having another file commander (manager) in addition to the explorer. There are quite a few of them, but I personally like two: Total Commander and Far Manager. The second, in my opinion, is perfectly suitable when various kinds of problems arise, for example:

• if there are a lot of files in the directory and Explorer freezes, Far will easily enter it and help you find or delete unnecessary files;
• you can easily and quickly change the attributes of any files (Far sees everything);
• when running old programs that need to pass certain parameters via the command line...

FAR Manager

Many users are put off by the appearance of this file manager (but I repeat, in terms of capabilities it is not inferior to the same Total Commander!). You quickly get used to the “blue” speakers, and they become like “family” (I could be wrong, but now he can easily change his appearance).

Now about what to do in Far in order to make hidden files visible:

Note: I have given all the button combinations for Far v.3, which are used by default.

3) Checking the flash drive for errors

Even if Far did not “see” the data on the flash drive, it may be worth checking it for errors (for example, if you incorrectly disconnected the flash drive from the USB port, this could very well happen. Or the PC turned off while copying information to it...). You can check using standard Windows tools.

To do this, you need to open “This Computer” (“My Computer”) and right-click on your flash drive: in the menu that appears, select “Properties”.

Then agree to scan the disk (by the way, Windows can immediately report that it found errors on it, as in my case).

Upon completion of the check, the file system of the flash drive will be restored. “FOUND.000” may appear among the new folders on the drive - it will contain recovered files (to read them, use the unCHKfree utility, for example). But as a rule, in most cases, after checking, the flash drive starts working in normal mode, and there is no point in messing around with “FOUND.000”...

4) Checking the flash drive with an antivirus product

If you have a standard classic antivirus on your system, check it with it.

Personally, I like ESET Scaner (the light weight of the program, coupled with powerful scanning filters, leaves most viruses no chance).

I’ll show you below how the scan works in ESET Scanner. After downloading and launching the anti-virus module (and it weighs only a few megabytes), I recommend enabling detection of potentially dangerous software and setting the scanning settings (number 2 in the screenshot below).

Next, it is advisable to select RAM, boot sector, system disk with Windows (usually this is “C:\”. If anything, such a drive is marked with the Windows icon), and the flash drive itself. Then you can start scanning.

The scanning time depends on the drives selected in the previous step, the size of your flash drive and the number of files on it. I recommend waiting until the process is completely completed.

If viruses are detected, it would be a good idea to run the system with several more antivirus products. I would recommend this material:

5) If information from the drive has been deleted

If the data on the flash drive was accidentally deleted by you (either a virus did it, or the drive was mistakenly formatted) - do not rush to despair. Most likely, most of the information will be able to restore . The main thing is to disconnect the flash drive from the PC and do not copy anything to it!

1. recovery of deleted files (photos, pictures, texts, etc.) from USB flash drives and SD cards -
2. recovery of deleted files from disks, flash drives, etc. -

Additions are welcome...

A compact USB drive, known to most users as a flash drive, is today considered the most common device for storing and exchanging various data. A frequently occurring problem: “No files are visible on the flash drive” can have quite disastrous consequences. After all, important documents of a confidential nature, unique photographs and other types of valuable information transferred to a Flash USB Drive device may be in a single copy. If this is your first time encountering a similar problem, do not panic. There is a high probability that the missing data is still there - on the flash drive. You just don't see them because they are hidden. To solve the problem of “invisibility”, let’s turn to the practical experience of experienced ones and consider the main aspects of digital restoration.

Two main reasons: why did the information disappear?

So, when you inserted a USB drive into your computer, you discovered that there are no files visible on the flash drive. In the vast majority of cases, it is the user who is the culprit of this kind of trouble. And most often, it is as a result of improper operation that the Flash device begins to work in “magician” mode. Of course, one cannot discount manufacturing defects in the production of a product and unfavorable accidents of a metaphysical nature. However, the harsh reality shows that the cause of the malfunction can be either hardware or software.

Files are not visible on the flash drive: ways to fix the problem

The first thing to do is to conduct a visual inspection of the subject of our attention. It is possible that the data transfer device is purely mechanically damaged. A once-spilled cup of coffee can also have a direct connection with the disappearance of files. Make sure that the contacts of the Flash drive are not oxidized. If the device is equipped with a signal LED, operability should be confirmed by the indicator lighting. However, if the computer detects a connected device, then, most likely, the “hero of the occasion” has software roots that could well be undermined by a malicious one. However, such “tricks” can be exposed as a result of the use of special software, but first...

Standard methods of combating “invisibility”

If you don't see any files on the flash drive, try the following:

• Connect the USB device to your computer.
• Use the key combination “Win+R” to open the “Run” window.
• Next, enter “cmd” in the checkbox.

• In the “Command Editor” write “Attrib -h -r -s / c /d k:\*.*”, where the Latin k should have the literal value of your removable storage device.
• Press Enter and hidden files will become visible again.

Second Windows solution: Changing system settings

It is quite possible that the folders and files located on the flash drive have been assigned the “hide” attribute. In this case, the Flash drive connected to the PC will appear empty.

• Go to the “Control Panel” menu.
• Now go to the “Appearance and Personalization” section.
• In the “Folder Options” block, activate the “Show hidden files” link.
• The last item in the list must be activated. That is, the item “Show hidden files, folders...” must be marked with a marker.

If this method does not have the desired effect, and everything is also not visible, try the method described below.

Option three: checking the parameters of one of the registry branches

As a result of a virus infection, malicious code can change entries in the Windows OS system log. Therefore, it is necessary to ensure the integrity of the parameters involved. It is worth noting that when working with the registry, extreme caution should be taken, since incorrect actions and incorrectly made changes can critically affect the full functionality of the Windows system as a whole.

• Using the "Run" menu, you need to open
• Enter the command "regedit".
• After the utility utility opens, follow the path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL.
• The “CheckedValue” key entry (right area of ​​the editor working window) must correspond to the value “1”.
• There should be nothing in the “Type” column except “REG_DWORD”.

If the entry did not match the specified pattern, your PC is probably infected with a computer virus, which means you need to check the system for the presence of “destructive code”.

An obvious question: “How to open invisible files?” and an effective answer to it

Algorithm of actions:

• Download Malwarebytes Anti-Malware Free on your PC.
• Launch the installed software.
• Scan all partitions of your PC hard drive and USB drive.
• If a “digital infection” is detected, remove the source of infection.

It is worth noting that in some cases, even after treating the hard drive and storage area of ​​the flash drive with antivirus software, the problem will not disappear. Because as a result of the destructive activity of unfavorable code, OS service files and even the disk structure could be changed. In such cases, the recovery process, and in the case of the system, a complete reinstallation of Windows, simply cannot be avoided.

How to recover lost data

As a rule, as a result of incorrect manipulations with removable media, beginners have the question: “Why doesn’t the flash drive see the files?” To resolve this kind of problem, you need to download and install a special program on your PC. Among the huge amount of similar software, the most attractive is the free data recovery utility Recuva, which you will learn about in the section below, and also learn the basic techniques for working with it.

Recuva is a free data “reincarnator”

So what needs to be done?

• Download this software product from the official website.
• After installation, run the utility.
• Select the type of information you are looking for. The most acceptable option is all files.
• In the next window, select “On the memory card”.
• Once you have confirmed your choice, the scanning process will begin.
• If the result turns out to be ineffective, go to the “Advanced Mode” tab in a special program window.
• Check all inactive items and repeat the startup process again.
• The files found in this way need to be restored. Click the button of the same name in the lower right corner of the program.
• Check the checkboxes next to the found files.
• After activating the “Recover” button, your data will be saved to the directory you specified.

As you understand, this program will also effectively cope with the possible problem when the memory card does not see files. However, with Recuva you can recover deleted information from almost any type of media.

Instead of an afterword

So, you have learned what to do if the flash card does not see files. Nevertheless, do not forget about basic operating rules, the observance of which guarantees long-term operation of the storage device:

• Do not save information to a flash drive that has not previously been scanned by antivirus software.
• Remember that you need to disconnect the USB drive correctly, deactivating it using the Windows tool: “Safely Remove Hardware”.
• You should not use the same flash drive in different systems. This warning is especially relevant for mobile storage devices (for example, SD memory cards).
• Don't forget to make a copy of the data from the USB drive to the hard drive of your PC.
• In some cases, to recover lost files from a specific modification of a storage device, you may need specific specialized software.

All the best to you and your flawless Flash devices!

is not only a tool for displaying sites, but also a tool for downloading files from the network to a computer. Today we will look at the main reasons why Yandex Browser does not download files.

The inability to download information from Yandex can be influenced by a variety of factors.

Reason 1: Lack of hard drive space

Perhaps the most common reason why a file cannot be saved to a computer.

Open Windows Explorer under "This computer", and then check the status of the disks: if they are highlighted in red, then you are very low on free space.

In this case, you have two options to get out of the situation: either save the files to a free local disk, or free up space on the current disk so that there is enough space to download the file.

Reason 2: Low network speed

Please also note that if your Internet connection is intermittent, the download will be interrupted, but the browser will not be able to resume it. In addition, loading problems will occur not only in Yandex, but also in any other web browser on the computer.

If you suspect that the inability to download a file to your computer is due to “bad” Internet, if possible, connect to another network to confirm or refute this guess. If the file was downloaded successfully when connecting to another network, then you need to worry about improving or changing your Internet connection.

Reason 3: lack of a specified folder for downloading files

By default, Yandex Browser is set to a standard folder for downloading files "Downloads", but as a result of a malfunction in the web browser or user actions, the folder can be replaced, for example, with a non-existent one, which is why downloading files cannot be performed.

Reason 4: Profile folder corruption

All information about the browser is saved on the computer in a special profile folder. This folder stores information about user settings, history, cache, cookies and other information. If for any reason the profile folder has been damaged, this may result in you being unable to download files from the web browser.

In this case, the solution may be to delete the current profile.

Please note that deleting a profile will entail erasing all user information stored in the browser. If you do not have data synchronization activated, we recommend setting it up so that all information is not irretrievably lost.

Reason 5: viral activity

It's no secret that the vast majority of viruses are aimed specifically at damaging the browser. If files on your computer from the Yandex web browser do not want to be downloaded, and in general the browser itself is unstable, we strongly recommend that you run a system scan on your computer for virus activity.

Reason 6: the browser is not working correctly

Actually, just as the previous reason can become the main factor in the incorrect operation of the browser, so can a conflict with other programs, system failures, and more. If the browser does not work correctly, you need to reinstall it.

Reason 7: download blocked by antivirus

Today, many antivirus programs act quite aggressively towards browsers, mistaking their activity as a potential threat.

1. To check if your antivirus is causing the problem we're looking at, simply pause it and then try downloading files to your computer again.
2. If the download was successful, you will need to go to the antivirus settings, where, depending on the manufacturer, you may need to allow downloading files in Yandex.Browser or even add this program to the list of exceptions so that the antivirus program does not block the activity of the web browser.

Reason 8: System failure

In rare cases, the inability to download files to a computer can be negatively affected by the operating system itself, which for various reasons may not work correctly.

As you can see, there are enough ways to solve the problem with downloading files from Yandex Browser. We hope these recommendations were useful to you and you were able to return your popular web browser to normal functioning.
