On a friend computer, we can not open or edit files because they are Locked, Renamed and maybe Encrypted. We don't understand the reason how that files becomes locked and inaccessible. Can be Windows Permissions, a Software or a Virus , involved? Downloading files from Internet with IE is impossible, also. Anybody know how we can handle this serious issues? Did someone know where we can ask this question or report this problem to find solutions? Thank you in advance Regards kb

try kaspersky RannohDecryptor.

Hi, Before going any further, please check whether you could change the files name back or not. Whether the security settings of the files have been changed? Whether you have the ownership of these files? It issue seems related to the virus, I suggest go to Safe Mode and use your anti-virus program or Microsoft Security Essentials to scan your system. After that, try to change the files name back to test the issue. If the files ownership have been changed, please try to Take Ownership of a File or Folder Hope this helps.Vincent Wang TechNet Community Support

Thank you, we will try this decryptor and I will post the result soon.kb

We tried to rename files as before, then, at opening displays strange characters. (that's why we thinking that files are encrypted). So , files can't be recovered by this way. In Safemode we scanned with: SpyBot Search & Destroy, Malwarebytes Anti Malware, IoBit Malware, Fsecure, Windows Defender, BitDefender online and Microsoft Security Essentials. Malwarebytes Anti Malware found this : " C:\Windows\winsxs\amd64_microsoft-windows-d..ostic user-resolver_31bf3856ad364e35_6.1.7600.16385_none_2129f6bd1f6002ae\DFDWiz.exe (Trojan.FakeAlert) " Fsecure found this : Gen:variant.[variant] - malware , Type : Rogue; Platform w:32 The ownership was not changed And modified files are all over the HDD ( On System and the second partition for data) We will try with kaspersky RannohDecryptor Thank you kb
