Avira DE-Cleaner is a new specialized security software from the makers of the popular antivirus software AntiVir. The program has been designed as an on-demand virus scanner that can be installed or used as a portable version. The tool has been created in cooperation with the Anti-Botnet Advisory Center, an initiative run by the Association of the German Internet Industry (eco) which is backed up by the German Federal Office for Information Security (BSI).

The goal of the advisory center is to aid and help computer users remove Botnet Threats from their computers. This is done by educating users about potential threats and securing computers, giving them easy to use tools at hand to scan their computers and remove infections, and working closely with Internet Service Providers who are informed about affected customers.

Avira's DE-Cleaner falls into the "easy to use tools" category. The program has been released with a German interface only at this point in time. Most users on the other hand should not have a problem using the tool, even if they do not speak German as the controls have been reduced to a bare minimum.

Let me walk you through the installation and use of the antivirus scanner:

Avira DE-Cleaner Installation, Use

It begins with the download of the program files after the application has been started on the local computer system. This is an automatic process that requires no user interaction.

The German terms of service are displayed. Information about the data that is collected by the application are available in English on the Botfrei website. The Akzeptieren (accept) button accepts the license agreement, Beenden (cancel) would close the application.

terms of service

The next page displays several options that require explanation. The "USB-Gerät kopieren" link offers to copy the software to an USB device for portable use.

The "Vollständige Systemprüfung durchführen" checkbox can be checked to run a complete system scan instead of a scan of the most important directories and files.

A click on Suchlauf starten begins the scan of the computer.

scan for malicious software

The processing time depends highly on the speed of the computer, the type of scan (complete, quick) and the storage devices and their files.

It is possible to cancel the scan at anytime with a click on the Abbrechen (cancel) button. Avira DE-Cleaner indicates malicious software in the line "Gefundene Schadsoftware".

The scan results window displays the number of potentially dangerous objects that have been found during the scan.

scan results

Here it is possible to select "Alle entfernen" to remove the objects from the system, "Details ansehen" to view details about the files that have been found during the scan or "Abbrechen" to cancel all operations.

It is recommended to select Details ansehen to look at the scan results before deleting files on the system.

delete dangerous files

Avira DE-Cleaner lists the files and their infection on the scan details window. The view lacks location information and an option to open the folders the files are stored in. The program seems to have found two phishing emails on the computer during the scan. I first thought that the program did scan my inbox, but it scanned only the mailbox files on the system (and suggested to remove those which is BAD).

The "entfernen" checkbox indicates if a file is included in the removal. The "Ausgewählte entfernen" button deletes the selected items, Abbrechen cancels the process.

Avira's security tool displays a summary in the end which lists the scanned files and folders, the time and malicious files it discovered during the scan.

A click on "Ausführlicher Bericht anzeigen" displays a log file of the scan. This can be actually pretty helpful to determine the location of the potentially dangerous files that have been found during the scan. I was able to determine that the program scanned the Thunderbird mailboxes on the computer which contained two phishing emails. I did not want to try the disinfection as it could very well corrupt the mailbox.

It is therefor advised to be very cautious if the program detects malicious files or data in mailboxes.

Users have the option to send the scan report to the Anti-Botnet Center which use it to improve their service. Bericht Senden would send the report, Bericht nicht senden not.


Avira DE-Cleaner appears to be using the Antivir engine for its scans. The core purpose of the program is to make antivirus scans of a system as easy as possible. The main problem that I see is that it does not provide enough information about items that it found, so that it is often difficulty to determine if the files should be deleted. There does not seem to be a quarantine which means that it is not possible to restore the files at a later time.

The program could do with an English user interface as it would increase the reach of the application. While it is not difficulty to use, most users do prefer information in a language that they speak, especially when it comes to PC security and file deletions.

Avira DE-Cleaner is provided for the Windows operating system. No further compatibility information are provided, it ran fine without problems on a 64-bit Windows 7 test system.

    Does it come back after every “moment” update?

  2. Baloney said on March 9, 2023 at 2:23 pm

    Yeah right.. Like this is going to stop defender from running =) This is comedy gold right here.

    no ‘about the author’ paragraph?

  4. Gregory said on March 9, 2023 at 4:19 pm

    For permanent disable defender is if removed complete from system no just change permission folder.

    Just this is joke.

  5. moi said on March 9, 2023 at 5:57 pm

    simpler, load Autoruns (SysInternals)
    – filter “Defender”
    – untag all entries
    – reboot
    nothing has changed since my 1st modification years ago

    I wouldn’t disable Defender imho, it has too many hidden roots inside Windows itself. One time I tried to uninstall it using brute force scripts and then the Onedrive feature stopped working definitely. A reinstallation was needed and since those times I prefer to maintain Defender untouched. It’s a better method to install another antivirus and it will disable Defender in a safer and easier mode (e.g., Avast is the best in this way, and also Panda Cloud Free is good too).

    You can not stop defender from running in background or remove it without some penalty. All you can do is to limit telemetry.

      It’s probably Smartscreen which is preventing WD from being disabled. Get rid of that and the problem should be solved: https://thegeekpage.com/disable-windows-defender-smartscreen/#How_to_disable_the_Windows_Defender_SmartScreen_via_Local_Group_Policy_Editor

    Remove Windows and go for Linux.

    1. basingstoke said on March 10, 2023 at 2:51 pm

      Linux sucks dude. Besides it’s not comparable to Windows, these OSes are in different classes entirely.

      1. Derp said on March 10, 2023 at 4:36 pm

        I use Linux as my daily driver. It’s far more stable than Windows. When’s the last time you used Linux, 2010?

      2. Bromosexual said on March 11, 2023 at 2:04 am


        You’re right, dude. Bro, linux is just a bunch of code that starts before the OS, dude. Brobrodude, that shit ain’t even got emojis, dudebrodudeman! Dudebro, it’s no way near as cool as Windows with its hardcoded abilities to make money off the user, bro. Yo brodude man, you’re the coolest dude ever man, bro. Dude.

      3. basingstoke said on August 16, 2023 at 7:20 pm

        Lol what? Windows 7 doesn’t come with any Emojis

  9. TelV said on March 10, 2023 at 4:46 pm

    Download Autoruns and remove the checkmark from Windows Defender. It doesn’t remove it, but it will never run. https://learn.microsoft.com/en-us/sysinternals/downloads/autoruns

    Just use “Defender Control”:

    Per this video,
    it also works on Windows 11 too…

  11. Someone said on March 10, 2023 at 9:26 pm

    Win Defender, is completly the most succesful free-built in antivirus of Microsoft. Really nice product. Saved my ass a lot of times. Has updated malware database, completly strong defence
    from whatever smart screen disables. Or if you want better and more upgrated (paid) program,
    you can go further. But defender is always on your side.

  12. CalixtoWVR1 said on March 10, 2023 at 10:03 pm

    Why would one disable Windows (or Microsoft) Defender in the first place?. I consider this to be playing with fire big time. Everybody knows that if one is using another A-V, Defender will be disabled on its own and won’t be in one’s way.

  13. Ed D said on March 10, 2023 at 11:09 pm

    Why would I want to disable Windows Defender in the first place? It’s a great anti virus in my opinion. Been using it since Windows 8 and and never had a problem or a virus. Why mess with a good thing, if it ain’t broke don’t fix it.

  14. owl said on August 17, 2023 at 1:57 am

    How a ridiculous article!
    I am thoroughly stunned.

    Why Should You Disable First-Party Windows Defender?
    I can only think that it is “malice or perversely intention (want you to buy a third-party AV where you can expect a back margin)” to guide invalidation without showing the premise.
    No sane company will use third-party closed source programs (such as AV).

    As I thought, “Ghacks Technology News” seems to be coming to downfall.
