    All downloaded files have wrong checksum SHA256 - affected all devices in my network....


    Dear Microsoft Community,I have problem with all devices in my network. When I download file this have wrong checksum and sometimes is also corrupted. This looks like malware. For example I downloaded Firefox installer from official Mozilla website and this installer have wrong SHA256 checksum. I checked it manually by cmd.exe and certutil command. Of course every other files/programs from another sources are also corrupted or have wrong hash.What I tried to resolve this issue?1 Reinstalling Windows 10 with clean install from iso from Microsoft media creation tool2 Reinstalling OS on all d

    Winows 10 somehow corrupts files during network transfer.

    The situation is following.

    I have a relatively large zip archive sitting on my network drive. If I copy and extract it locally or try to extract it over the network the archive utility tells me that there are checksum errors. The other symptom is that if I try to get the sha256 checksum
    of the file itself, the Get-FileHash cmdlet always produces different sums if run over the network.

    The router and the network drive are not on the list of suspects as my other computer can read, write, extract files from this drive with no issues.

    Something wrong with downloads?

    maybe list the specific file you are trying to download. I also just grabbed a download with no issues, and good speed.

    Thank you for your suggestion to download vmguest.iso . I did that and installed in my VM setting IDE controller 1 DVD drive Image Iso: vmguest.iso.

    I have legacy adapter selected.

    It still does not provide Integration service. Any Suggestion?

    I have not done anything else.

    what is do I do with

    Checksums

    • vmguest.iso, MD5: e36d4976a4fa8b38726670eb332c4fea
    • vmguest.iso, SHA1: 415d62038cf28c39af2ca63076a7df91a4524314
