What is order "prefetch hidden junk files" in fact?

Received a phone call today from someone claiming to be from Microsoft, saying that my computer has been infected and crashing, he gave me a 'hidden prefetch junk files' command to enter.

I obviously did not do because I knew it was a scam right away.

But my question is, what is he still doing this command?

The part of prefetch would display only your Prefetch folder. This is used by Windows to speed up your computer startup. The part 'hidden junk files' is meaningless. The scammer you to type only asked that as part of his attempt to deceive believe you there is something wrong with your computer. He awaits for you are not familiar with the contents of the Prefetch folder and try to convince you that what you see is evidence of a virus. Another tactic they use is to make you open Event Viewer, and then claim that normal Windows system events are the result of viral infections.

  • What is "c: / program hidden folder files/Windows apps and why I can't access it?"

    Hey there,

    "You don't have currently not allowed access to this folder. Click on continue permanent access to this folder. »

    Then, like a good boy, I click on continue and...

    "You have been denied permission to access this folder."

    But wait... I can click on a link hyper to the Security tab, Ok...

    "You must have read permissions to view the properties of this object. Click Advanced to continue. »

    Don't panic!

    "You must have read permissions to view the properties of this object. Click on continue retrying with administrative permissions. »

    Okey Dokey!

    Takes me of course to features advanced security where it is said the owner of the folder is "Trusted Installer" and "directors" shows correctly with the settings read and execute access to this folder, subfolders and files.

    Can someone please clarify what this file is for and why there is a folder on my RT Surface that I can't access?

  • I have windows vista and when I click on a shortcut on the desktop I have a pop up asking what file to open it with. In order to open the file I find the actuall file.

    I have windows vista and when I click on a shortcut on the desktop I have a pop up asking what file to open it with. In order to open the file I find the actuall file. This also occurs when you download the software, which makes it difficult, because the file is not on the pc yet. All solutions?

    Looks like you may have a virus or other malware. Get your updated antivirus program and boot into Safe Mode. Note that some viruses can hide from your normal antivirus program, so you really need to scan in Safe Mode. To enter in Safe Mode when you turn on first, press F8 on every seconds until you get the menu, and then select Safe Mode. Then run a complete system scan.

    If that suits him fine. If this is not the case, use system restore to go back to an earlier date at the beginning of the problem. To run system restore, click Start-> programs-> Accessories-> System Tools-> system restore. Click on the box that says show more restore points.

    You can check the corrupted system files. Open an administrator command prompt and run SFC if the above does not help. Click START, and then type sfc in the search box, right-click to SFC. EXE and click run as administrator. Then, from the command prompt type sfc/scannow.

    Finally if all else fails, you can look at the rather cryptic system event log. To make, click Start-> Control Panel-> administration-> event viewer tools. Once in Event Viewer system log-click and scroll entries looking for these "error" with indicator see if you can find guidance on where the problem may be.

    I hope this helps. Good luck.

    What folder & junk files in windows 7?

    Everything that is installed as part of Windows 7 is there for a reason. You can disable and customize many features, but you should really leave it as it is, especially if you don't know what you're doing. You might accidentally delete something you shouldn't.

  • What is the Temp etilqs xKTXRBvWnu6 file?

    Everytime I open my browser Firefox Win Patrol reports a hidden file. I use XP Pro with SP2, and they are always under C:\Documents and owner Settings\Temp. These files always have etilqs as a prefix with the last group of numbers and letters of Exchange to the next time I open Firefox. It's more embarrassing, it's more boring near harassment, having to respond to the report of WinPatrol. There is no way to ignore it in Win Patrol settings so I have to uninstall Win Patrol or Firefox. Do you know what are these hidden temporary files and how can I stop being a constant nuisance whenever I try to use Firefox? Thanks for any help you can give me.

    WinPatrol is tenacious tell you these because that you have enabled the cookies of the monitor, which is not recommended.

    For instance, you may see many files that start as etilqs_ followed by random names. These are database files used by the public domain database called SQLite. Both Chrome and FireFox use SQLite to store data including cookies.  Another common hidden legitimate file will start with api-ms-win- or ext-ms-win.

  • What is the path hidden pictures on a macbook pro?

    What is the path hidden pictures on a macbook pro?  I want to look at the structure of files and compare the list of photos to remove duplicates.

    / Users/Myusername/images/Photos\ Library\ 2. photoslibrary?

    ~/Library/?

    Thanks for any help.

    If you try to delete the duplicates by deleting files directly in the package of the photo library you will damage the photo library.

    Photography shops photos within a structure of database and the objects are distributed everywhere. There is no way tor record delete a single picture using the Finder.

    The photo library is a set, a folder with subfolders and data bases. For a single photo that you import pictures will store the original image file in a subfolder 'Masters' (~/Pictures/Photos Library.photoslibrary/Masters/) or in iCloud, according to your settings.  It will create an additional stamp file, files with faces found thumbnails and previews in the folder found, to share with other applications in the media browser.  Always use Photos interface to remove the photos or the library will become inconsistent.

    You can look inside the set of files grouped by ctrl-clicking on the library and using the command 'Show Package Contents': but make sure you do not move the files.

    To remove duplicates consider using a double Finder program:

    These applications are compatible with Photos and safe to use:

    If you have duplicates of a different pixel size in your library as well, then consider Photo Sweeper. We can compare the histograms or bitmaps from photos, so you can detect duplicates as well edited.  In addition, you can set up rules assigned to photos to keep and which to dispose, for example to give preference to more recent photos, photos with the largest size of pixel or photos with metadata.

    PowerPhotos is a great tool to have, when you work in Photos for navigation of several libraries of Photos at once and to see the photos annotated with metadata. It can move photos between libraries and help you merge libraries. But the duplicate detection is not as versatile as in Photo Sweeper. It can detect mainly exact replica.

    I don't know much Duplicate Annihilator, so I can't say how it will compare to the other two.

  • prefetch folder deleted files

    Apparently, somehow I deleted the files in the prefetch folder. I have vista home pro. A way to restore or is it as critical, as they say.

    Hello

    The prefetch folder is a subfolder of the Windows system folder. The prefetch folder is independent now, and there is no need to remove or to empty its contents.

    The prefetch folder will be created automatically at the next reboot, but Windows will take a little longer to start completely for the first instance only.

    No program is good to do things like that. Avoid all the

    Registry cleaning programs are all snake oil. Cleaning of the
    registration is not necessary and is dangerous. Let alone register and
    do not use any registry cleaner. Despite what many people think, and
    What software record cleaning suppliers are trying to convince you,
    have unused registry entries is not really make you hurt.

    The risk of a serious problem caused by a registry cleaner by mistake
    delete an entry you need is much greater than any potential benefit
    It can have.

    Let me stress that neither me nor anyone else who warns the
    use of registry cleaners never said that they always cause
    problems. If they have always caused problems, they would disappear from
    the market almost immediately. Many people have used a registry
    cleaner and never had a problem with it.

    The problem with a registry cleaner is that it carries with it
    the risk of a significant problem. And since there is no
    benefits of using a registry cleaner, running that risk is a very bad
    good deal.

    Thanks for posting your query in Microsoft Community.

    I understand that you are having problems removing the aforementioned file. Basically, it's one of the hidden Windows files, and I suggest you try the following methods to remove.

    Method 1:

    I suggest you to run Disk Cleanup and check if that helps you remove unwanted files.

    To open Disk Cleanup:

    (a) press the Windows key + R

    (b) type: %windir%\system32\cleanmgr.exe

    (c) click OK.

    Important: Exercise of disk cleanup on the hard disk, a risk of losing important data available on bad sectors on the disc is involved.

    If the problem persists, try the following method.

    Method 2:

    You can also delete the file mentioned when running your system in Mode safe. See the following steps to start the system in safe mode and then delete the file.

    1. Press Windows key + R, type in msconfig and press enter.
    2. Go to the Boot tab, select Boot , choose a minimum and click OK.

    3. Click restart.

    4. Press Windows key + R.

  • What is happening in the original file of the photo when I import it in Photos and I have the "Delete after import" box checked?

    What is happening in the original file of the photo when I import it in Photos and I have the "Delete after import" box checked?

    When organizing photos for Photos for Mac app, I find that the Photos makes "copies" of files within the library of Photos and must reference a file if your settings are such that you do not copy the original files in the Photos app.

    Trying to manage the disk space for the Macbook Pro.

    The delete after import is available only when you import a device - a camera, card, an iPhone, but not when you import files from a folder on the system drive.

    You can delete the local image files of your system drive yourself, once you have imported the Photos and they were copied in the photo library.

    I would never use the option "delete after Import. The files will be deleted until you can check if the files have been imported correctly. If you find out later, that some of the imported files are corupted and illegible, it will be repeated o toolate import, because the files have been deleted from the device. Or worse, if pictures should plant a reason any during the import, all the pictures will be lost, if you have enabled "delete after import.
