Bit Defender blocking windows update KB4574727

Windows latest update KB4574727 is blocked from updating Windows by BD. I get the messages:

Antivirus

I have tried both through Windows Update and by downloading the file from Microsoft and trying a manual install, both with the same result.

Any ideas?

  • Experiencing the same, went to reddit first with it. Seems bitdefender is not happy with this update.

  • I have had the same issue, i just deleted the update for now and will try later.

  • I ran into the same issue yesterday, found an old link (2016) on forum, in German, mentioning the same virus name.

    Seems like it is a false positive, now waiting on finding out more, before I do anything. It's on my W10Home machine, so I delayed updates on my W10Pro machine, and have not seen anything yet there.

    Waiting on BD... Impatiently...

  • lol.....I once remember Bitdefender flagging all Windows dll files as malware. way back in 2010 I think.


    This company will never learn from their mistakes.

  • I'm surprised and disappointed that BD has not responded here, but according to other sources have issued a new update, whitelisting the W10 KB4574727...

  • Hello everyone!

    We have acknowledged and resolved the false positive detection. Now you should be able to update to Windows 10 KB4574727.

    In the meantime, we would like to thank you all for your patience, as we understand the impact that such a situation can create.

    Kindly reply to this thread if the error still persists on your device after updating Bitdefender.

  • My computer is still affected. Have tried updating BD then restarting the computer with no result.

  • Tried again today (Saturday) and still no joy. Whatever fix you applied to BD still doesn't work for me. I no longer get any BD messages when attempting the update, it just fails to install.

    Any ideas?

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor.
