Hi,
Thank you for your advice. Unfortunately, by the time I found where the file Removal Guide by Osiris was downloaded, The last open browser (Safari) crached and I am unable to go online with that Laptop. Whenever I click on an icon or on a folder, I receive a message: "Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item."
I think my last resort is gonna be to wipe out C:\ and reinstall from the recovery? How do I do that correctly? Or is there another way to solve my problem.
Once again thank you.
