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!
