Hi Juliet.
I used normaly my computer with Internet Explorer only. No problem.
This morning, without having restarted the computer, I have a "Microsoft Guenine Warning" displayed.
I use an ASUS X501A Laptop with preinstalled Windows 7 also available on a hidden partition with valid licence.
For information, I was always able to make automatically the window updates.
But this time, I guess my sytem will be blocked (by Microsoft) at the next restart.
I guess important system files have been altered/blocked with last scan (as suggest Microsoft online help).
I don't know how to restore them from Malwarebytes (and which ones).
Of course, I can recovery OS by pressing "F9" to access the hidden partition.
To avoid this final solution (that's why I'm disturbing you on this forum), you may find a trick to solve this issue.
Find attached all Malwarebytes Logs and screeshots for the Guenine warning.
Kind Regards,
DJ. Tarek, France.
