Reco ransomware removal instructions
What is Reco?
Reco is a piece of malicious software, belonging to the Djvu ransomware family. This program operates by encrypting data and keeping it on lockdown, until a ransom is paid (i.e. until a decryption tool/software is purchased). As this ransomware encrypts data, it renames files with the ".reco" extension. Therefore, a file titled something like "1.jpg" would appear as "1.jpg.reco" and etc. Once this process is complete, Reco creates the "_readme.txt" text file, which contains the ransom note.
The note in the text file states that all the victim's files have been encrypted and to decrypt them, they need to buy the decryption tool and unique key. The developers of Reco offer a free decryption of one file as proof of their ability to restore the encrypted data. They will do so, if the file does not contain any valuable information (likely implying that it must not be a database, backup, large excel sheet or similar). The message further tells that the cost of the decryption tool and key is 980 USD. However, if affected users contact the cyber criminals within 72 hours, it can drop by 50 percent. To get more information and further instructions, victims are to contact the criminals via the email addresses provided. If they do not receive a response in six hours, users should check their "Spam/Junk" folders for the reply. Programs like Reco employ strong encryptions, which can only be decrypted with the software used for the encryption. Despite the fact that there are no free tools capable of "cracking" these encryptions, users are strongly advised against meeting the demands of cyber criminals. There are no guarantees that once the ransom is paid, the decryption tools/software will be sent. Frequently in cases of ransomware-type infections, the developers of these malicious programs do not hold up their promises. Victims' data remains encrypted, thereby permanently lost. The only possible solution is to restore the files from a backup. However a backup copy had to be made before the infection and stored separately.

Xoza, Angus, Mike are just a few examples of ransomware-type software similar to Reco. Nearly all programs of this kind share certain similarities - they encrypt data and demand payment for its decryption. However, they differ by what cryptographic algorithm they use (symmetric or asymmetric) and the size of the demanded payment. Ransoms typically vary between three-digit and four-digit sums (in USD). Usually, cyber criminals prefer digital currencies (e.g. cryptocurrencies, pre-paid vouches, etc.), as transactions of such are difficult/impossible to trace. In most cases, manual decryption (without the involvement of the ransomware developers) isn't viable. It is only possible, if the ransomware in question is still in development and/or has bugs/flaws. To protect files from data encrypting or damaging attacks, users are advised to create backup copies and keep them in remove servers and/or unplugged storage devices. Ideally, multiple backups should be stored in different locations.

To eliminate Reco virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
Irrelevant and suspicious emails received from unknown senders should never be read. Attachments found in such must never be opened, as they themselves contain the infection. Users are recommended to only use official and verified download channels. Installed programs should be kept up-to-date via functions/tools provided by the legitimate developers. Software should be likewise activated using genuine tools, instead of illegal ones ("cracks"). It is strongly advised to have a dependable anti-virus or anti-spyware software installed and updated. Such programs should be used to perform regular scans and for the removal of potential threats. If your computer is already infected with Reco, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

IMPORTANT NOTE! - Aside from encrypting data, ransomware-type infections from Djvu malware family also add a number of entries to the Windows "hosts" file. The entries contain URLs of various websites, most of which are related to malware removal. This is carried out with the intention of making users unable to access malware security websites and seek help. Our website (PCrisk.com) is also on the list. Removing these entries, however, is simple - you can find detailed instructions in this article (note that, although the steps are shown in the Windows 10 environment, the process is virtually identical on all versions of the Microsoft Windows operating system).
Screenshot of websites added to Windows hosts file:
There currently are two versions of Djvu ransomware infections - the old and new ones. The old versions were designed to encrypt data by using a hard-coded "offline key" whenever the infected machine had no Internet connection or the server is timing out/not responding. Therefore, some victims were able to decrypt data by using a tool developed by cyber security researcher Michael Gillespie. However, since the encryption mechanism has been slightly changed (thus, new version), the decrypter no longer works. If your data has been encrypted by an older version, you might be able to restore it with the aforementioned tool (download link). It supports a total of 134 file extensions and you can find the entire list in the "About" screen.
