The website of the Ukrainian cyber police published tips to users whose computer systems are infected with the Petya virus, how to recover partially encrypted data. Completely infected and encrypted computers do not yet know how to recover, the message says..
"To restore partially encrypted data, you need to download the Windows installation disk and after boot, if the hard disks are not encrypted, the boot operating system will see them and you can start the recovery," advise the police.
For Windows XP, select "to restore Windows XP using the Recovery Console, press R" in the setup menu, and press.
For Windows Vista, select the "Restore computer health" item and enter the command bootrec / FixMbr in the options window.
The same command works on Windows 7, Windows 8 and Windows 10.
After recovery, you need to check the disk for antivirus programs. Detailed instructions can be found on the website of the cyberpolicy.
