From Kaspersky Lab:
Kaspersky RectorDecryptor fights against Kaspersky RectorDecryptor detections. ybercriminals use Trojan-Ransom.Win32.Rector for disrupting normal performance of computers and for unauthorized modification of data making it unusable. Once the data has been "taken hostage" (blocked), its owner (user) receives a ransom demand. The victim is supposed to deliver the ransom in exchange for pirate's promise to send a utility that would restore the data or repair the PC.
