The number of requests to Doctor Web's Technical support service from Western European users, who received an e-mail with the subject "Ute Lautensack Vertrag Nr 46972057" has increased in the last 24 hours. The e-mail contains the following text:

An archive file named Abrechnung or Rechnung can be attached to the message. If the attached application is launched, the Trojan encrypts files found on hard disks.

A warning from Doctor Web: do not open attachments in these e-mails! If the Trojan has encrypted files on your computer, follow the guidance below to avoid loss of valuable information:

  • Notify the police.
  • Never attempt to solve the problem by reinstallling the operating system.
  • Do not delete any files from the heard drives.
  • Do not try to restore the encrypted data on your own.
  • Contact Doctor Web's virus laboratory When file a request, select Request for curing. This service is provided free of charge.
  • Attach a file encrypted by the Trojan to the ticket.
  • Wait for a response from a virus analyst. Due to the large number of requests it may take some time.
