This access denied msg from Kaspersky Total Internet Security pops up every time my Windows system boots up, and every time Microsoft Edge was open and closed.

Googling mmjdebklmfjajmoplcloodegnkanahmm.js return 0 result basically.

I suspect that perhaps one of the MS Edge extensions installed is causing this, here're the list of them:

  • 1Password
  • All Video Downloader Professional
  • Dark Reader
  • Privacy Badger
  • uBlock Origin

All extensions were installed via MS extension store, none from external sources like Chrome Store. I've tried to uninstalled all the extensions, but the Access denied issue persists.

Hello to all who should have the same problem. I was able to further isolate the extension in question in Microsoft Edge, and the trigger is the Snapstream video downloader extension. After I removed this extension from Edge, Kaspersky no longer reports a malicious link. Thank you for all the help here on the board, keep up the good work.


thanks Berny ?
