    The XP-version of Bandizip is installing old files of 7-zip (version 16.0.2 - May 2016) into a subfolder of Bandizip.
    These files can be exchanged with newer versions:

    wouldnt it be better to suggest this to the vendor of bandizip?

    the comparison to other archivers is much outdated, in special winrar.

    i have doubt on software not using or updating original libraries.
    the changelog of bandizip dont offer security fixes but i assume there are.
    concerning 7zip bandizip uses some very outdated and high vulnerable code:

    not recommended!

    "Fixed" in 18.04beta ("Now 7-Zip doesn't use "Large Pages" on Windows 10 up to revision 1709 (16299).")

    7-Zip v18.04 beta (April 25, 2018)
    Website
    Download
    Code:
    - The speed for LZMA/LZMA2 compressing was increased
       by 8% for fastest/fast compression levels and
       by 3% for normal/maximum compression levels.
    - 7-Zip now shows Properties (Info) window and CRC/SHA results window
      as "list view" window instead of "message box" window.
    - Some improvements in zip, hfs and dmg code.
    - Previous versions of 7-Zip could work incorrectly in "Large memory pages" mode in
      Windows 10 because of some BUG with "Large Pages" in Windows 10.
      Now 7-Zip doesn't use "Large Pages" on Windows 10 up to revision 1709 (16299).
    - Some bugs were fixed.

    Sorry I didn't see this your post.
    Which software would you recommend then?
    Light.
    To be protected by MBAE without false positives with my custom settings (7-zip in my opinion does not work).

    i use winrar (latest final) and 7zip latest build. but i cannot say if they will work on an outdated xp. as i wrote elsewhere - it does not matter which outdated software runs on xp - because it already has >1500 security holes. ^^

    I do not like Winrar.
    7-zip has the problems I already mentioned with MBAE.
    So I continue to use Bandizip.

    I will not go into the issue of XP insecurity.

    The vulnerability in Rar unpacking code is a vulnerability that affect only 7zip or WinRar also?

    Does anyone know recommended settings in Windows Defender Exploit guard, to protect 7-zip?

    Thanks, looks good. I will have to study it, it looks like what I need to know, as far as the principles go.

    In this particular case, 7-zip has folders in both Program Files and in Program Files (x86), and some of the files appear to be the same. Furthermore, I must admit that I don't know which of the various files composing this program are the exploitable ones.

    If anyone has some insight into this...

    Save as Settings-7-Zip.reg
    Code:
    Windows Registry Editor Version 5.00
    
    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options]
    
    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\7z.exe]
    "MitigationOptions"=hex:11,12,11,01,11,01,11,11,00,00,11,01,00,01,00,00
    "MitigationAuditOptions"=hex:00,00,00,00,20,00,22,02,00,00,22,02,00,02,00,00
    
    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\7zFM.exe]
    "MitigationOptions"=hex:11,12,11,01,11,01,11,11,00,00,11,01,00,01,00,00
    "MitigationAuditOptions"=hex:00,00,00,00,20,00,22,02,00,00,22,02,00,02,00,00
    
    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\7zG.exe]
    "MitigationOptions"=hex:11,12,11,01,11,01,11,11,00,00,11,01,00,01,00,00
    "MitigationAuditOptions"=hex:00,00,00,00,20,00,22,02,00,00,22,02,00,02,00,00
    

    Import into registry and try with 7-Zip. I use this almost daily on latest Windows 10 system and works well for me with 7-Zip. Windows and 7-Zip are both 64-bit in my test scenarios. Arbitrary Code Guard (ACG) is a great mitigation for 7-Zip. You can always change the mitigations in WDEG after importing (you have to close and re-open WDEG to show). And you can delete those three keys if it does not work well for you.

    P.S.

    For XP Users:

    Even after installing version 5.23 of Bandizip for XP output today it is necessary to replace the files.
