Windows 10: Confused about EFS encryption

EFS encryption has never been anything but trouble for me (and probably for most people), and I would love to be able to turn it off completely. I followed the steps on this page:
Disable Auto Encrypt Files Moved to EFS Encrypted Folders in Windows and I'm wondering how free I am from encryption now. The note says the system will still encrypt when copying files, and I'm only safe from encryption when moving files. I'm not sure if that means my system will continue to encrypt a file every time I copy it, or if I'll be free of the problem now. Could anyone please tell me in which circumstances my system will continue to encrypt my files? Thank you for your help!

Backup the EFS encryption key file


Yesterday I installed OneDrive app and linked it to my office 365 enterprise University account. Since then, every time I turn on my pc, I receive a warning about backup of the encryption key from EFS application. But I have never used bitlocker.
I did some search online and I got the list of all encrypted files: there are thousands of files and belongs to Apps, like facebook, onedrive, inkscape and so on.
So my questions are:

• why did that message suddenly appear?
• why are those files encrypted?
• do those files have to be encrypted?
• bitdefender has just found Gen:Trojan.Heur2.GZ.@FZ@bq2Abpn in temp folder. Could I have got a ransomware that is encrypting all files?

Thanks in advance!

 

Can I recover encrypted files with EFS without having key.pfx file ?

Hi Michael,

The Encrypting File System (EFS) is a built-in encryption tool for Windows. It is used to encrypt files and folders on your computer. You can reverse the encryption to access your files again. To decrypt folders, follow the steps below:

• Right-click the folder or file, then click Properties.
• Click the General tab, then click Advanced.
• Uncheck the Encrypt contents to secure data checkbox.
• If you are decrypting folders, select the option Apply changes to this folder, subfolder and files.
• Click OK, then click OK again to exit the window.

Let us know if the solution above works for you.
