Opera creating explorer.exe, is this OK?

  • A few days ago Malwarebytes started complaining about a file, explorer.exe in my temp folder. It turns out that whenever I start Opera this file is created and every time the file is created Malwarebytes complains. After chatting with folks over at Malwarebytes I have decided to uninstall Opera. I am wondering if the creation of the explorer.exe file is expected behaviour and why Malwarebytes things it's malware.

  • Probably some extension, not something that Opera does on my computer.

  • Yeah, it's definite not something Opera does on its own.

    In addition to uninstalling Opera like you did, if you didn't choose to also delete all your Opera data, also delete "C:\Users\yourusername\Appdata\Roaming\Opera Software" and "C:\Users\yourusername\Appdata\Local\Opera Software". Also, double-check that "C:\Program Files\Opera" is gone. If not, delete it.

    Also, goto "C:\Users\yourusername\AppData\Local\Temp", select all files in it with ctrl + a and shift + del the selection. You can tell windows to ignore any files it can't delete. You can do the same with "C:\Users\yourusername\Downloads" if you don't have any files in there you want to save.

    Then, download opera from opera.com and install it. You should then be fine. If it does it again, check opera://extensions and make sure there are no extensions installed that you didn't install.

    There is a related thread in the Malwarebytes False Positives subforum from this year.

    A staff member replies that they will "fix it shortly".

    Being not a member on this forum I can't access the attachments for a closer look.

    Using the current Opera version without any third party extension on Windows 7 32-bit such explorer.exe isn't created on my computer.

  • Thanks guys! I uninstalled opera and ensured that all data was deleted. That seemed to do the trick. I no longer get the explorer.exe file showing up whenever I start Opera.
