How to Remove Zenis Ransomware and Recover Encrypted Files

Win XP

What is Zenis ransomware

Zenis encrypts files on the infected computer, renaming them to Zenis-[2 random characters].[12 random characters], and leaves ransom notes (Zenis-Instructions.html) in folders with encrypted files. Zenis ransomware has been analyzed by security researchers, and Michael Gillespie (@demonslay335 on Twitter) has found a weakness in the ransomware that allows decryption of files. That weakness is not released publicly lest the ransomware developers find out and fix it. Users who wish to decrypt their files for free can contact Michael Gillespie (however that won’t be quick: there are a lot of victims, and the decryption itself is time-consuming). It is quite possible that Zenis developers will find the weakness and release a new, more secure version of ransomware in the future; in that case you can use this guide to try recovering your files by other methods.

How to Remove Sigma Ransomware and Recover Encrypted Files

How to remove Sigma virus and decrypt files

What is Sigma ransomware

Sigma ransomware is distributed via spam emails containing .docx or .rtf attachments with macros embedded. If a user has macros enabled, the script gets executed and downloads ransomware. Unlike most ransomware, Sigma doesn’t add new extensions to encrypted files and just creates ransom notes (ReatMe.txt and ReadMe.html) inside folders that contain encrypted files. At the time of writing no free decryptors exist, and the decryptor that ransomware developers offer in exchange for payment doesn’t work very well, according to users who have paid the ransom. Supposedly the decryptor crashes when encountering certain sorts of files, and some of the files stay encrypted as a result. In addition to decrypting files, there are some methods of file recovery that may or may not work in each particular case. You may follow this guide to remove Sigma and try to recover encrypted files. READ MORE

How to Remove Arrow (CrySiS) Ransomware and Recover .arrow Files

Win XP

What is Arrow ransomware

CrySiS or Dharma ransomware encrypts files on the infected computer and upends one of several extensions to encrypted files. The newest variant uses .arrow (.[marat20@cock.li].arrow, .[blammo@cock.li].arrow, .[java2018@tuta io].arrow, .[helprestore@cock.li].arrow) extension. Right now there is no free decryptor, and there may never be one. First two variants of CrySiS (.crysis and .dharma) had free decryptors released eventually but none of the later variants (.wallet, .arena, .cesar, .java) have so far. If your files have been encrypted by CrySiS and you don’t have back-ups, your best bet would be to back up encrypted files in case the free decryption tool is released in the future, and meanwhile try some methods of file recovery that may be able to restore at least some of the files.
