A trojan infected file that Comodo was not able to detect

  1. If you already have the comodo internet security or comodo cloud antivirus, just do a scan, download the shadow explorer https://shadowexplorer.com/

  2. With the system clean and protected with the comodo internet security or comodo cloud antivirus, install the shadow explorer and open it;

  3. After it appears on your screen, click where the unit indication will be (C: D: …);

  4. Select the drive if you have more than one partition or devices, navigate to the folders where the files were before they were encrypted, create a separate folder, drag and drop or copy and paste the files you want to recover using shadow explorer
    or if the above steps are confusing, you can see the link for how to use the shadow explorer program: ShadowExplorer.com - Manual

NOTE: Decrypt files infected by trojancrypt, only allowed thanks to restore points (a kind of non-complete system image), then shadow explorer, allows ordinary users how do I access files.

Sorry my english and and repeating text.
