What is Arrow file
.Arrow is a file extension that is used by the Arrow ransomware belonging to the Crysis/Dharma family to mark files that have been encrypted. Arrow ransomware is a malicious program that encrypts user files and demands a ransom for a key-decryptor pair that is necessary to decrypt the affected files. It uses a strong encryption system and a long key, which virtually eliminates the possibility of decrypting files without a key. Files encrypted with .Arrow extension become useless, their contents cannot be read without the key that the criminals have.
Text presented in the Arrow ransomware pop-up:
All your files have been encrypted!
All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail email@example.com

What is Arrow ransomware
Arrow ransomware is one of the variants of Dharma/Crysis ransomware. The most common source of infection is cracked apps and games, torrents files, freeware, Windows and Microsoft Office activators, and other similar software. Upon execution, it encrypts files using a key that is individual for each computer. Arrow uses a very strong encryption system, which eliminates the possibility of determining the key, even using a super computer. The encryption process is very fast, regardless of what is in the file, the virus can easily encrypt it. Arrow ransomware can encrypt almost all files that are on the computer, including those located on network drives. The only thing that the virus does not encrypt is the files that are necessary for the Windows OS to function normally. Below we list some types of files that can be encrypted by the ransomware:
.wire, .bc7, .wps, .zip, .fos, .dwg, .xmmap, .xbplate, .xx, .raw, .bay, .zw, .wpt, .rim, .sr2, .esm, .rofl, .xlsm, .rb, .bc6, .cfr, .mp4, .pfx, .zdc, .xlsb, .wot, .t12, .qdf, .bkf, .ncf, .wbz, .itm, .eps, .wmd, .bik, .zif, .xld, .wsc, .kf, .dba, .r3d, .hvpl, .itdb, .hplg, .desc, .wcf, .mdf, .ybk, .pptm, .nrw, .dmp, .bar, .1st, .sid, .png, .xxx, .vtf, .x, .xml, .wmv, .m3u, .ysp, .3fr, .pptx, .rwl, .pem, .dng, .rw2, .xyw, .wdp, .wb2, .jpeg, .xwp, .pef, .tor, .lrf, .y, .xdb, .xy3, .7z, .zabw, .xf, .vdf, .wp5, .raf, .wpd, .srf, .xlsx, .asset, .js, .docm, .ff, .wma, .sum, .x3f, .ibank, .wm, .iwd, .wdb, .x3d, .jpe, .wsh, .wp7, .3dm, .pst, .xls, .xls, .csv, .crw, .dazip, .dbf, .flv, .yal, .cdr, .cer, .wsd, .qic, .odb, .xlsm, .xdl, .z3d, .db0, .2bp, .ptx, .psd, .xmind, .xbdoc, .z, .odm, .wps, .wbm, .lbf, .xlk, .odt, .wpb, .docx, .indd, .wpl, .wav, .0, .wpg, .arw, .wpe, .wri, .dxg, .t13, .1, .tax, .doc, .yml, .avi, .xyp, .iwi, .map, .py, .wp4, .hkdb, .xlgc, .icxs, .erf, .syncdb, .wgz, .sie, .mdbackup, .wma, .forge, .itl, .gdb, .fpk, .ods, .fsh, .odp, .pkpass, .big, .bsa, .svg, .css, .p7c, .mddata, .bkp, .rtf, .mov, .kdc, .ztmp, .webp, .vfs0, .xar, .menu, .wbd, .orf, .zi, .accdb, .wotreplay, .x3f, .ntl, .wpd, .p12, .blob, .epk, .cas, .lvl, .wp6, .wmf, .psk, .3ds, .slm, .litemod, .vpp_pc, .der, .srw, .vpk, .sb, .jpg, .gho, .ai, .arch00, .ppt, .ltx
When a file is encrypted, ‘.id-USERID.[EMAIL-ADDRESS].Arrow’ is appended at the end of its name, that is, if you had a file of ‘document.docx’, then a file with the name ‘document.docx.id-USERID.[email@example.com].arrow’ will appear in its place. If you change the file name, just delete the added extension, then nothing will change. The file will remain encrypted, and as before, this file will not be possible to open in the program with which it is associated.
Perhaps you found on your computer or its desktop a new file called ‘FILES ENCRYPTED.txt’, which for some reason is not encrypted. An example of such a file is given below.
Text presented in the FILES ENCRYPTED.txt file:
all your data has been locked us
You want to return?
write email firstname.lastname@example.org
This file is very important, in addition to containing a ransom demand, it also contains information that allows you to contact intruders. According to the message, the victim is invited to contact the attackers using the given email address. In response, the authors of the virus will give a Bitcoin address to which the ransom must be transferred. Of course, you should understand that there is no guarantee that the attackers, after receiving the ransom, will provide you with the key necessary to decrypt your files. In addition, by paying the ransom, you will push attackers to create a new ransomware.

|Removal||Arrow ransomware removal guide|
|Recovery||Arrow File Recovery|
As we have already said, Arrow is not the first ransomware belonging to the Crysis/Dharma family. The fact that to date, antivirus companies have not created a way to decrypt files, and just have not found a 100% way to protect the user’s computers, indicates the complexity of the ransomware and the method that it uses to encrypt files. Nevertheless, you do not need to despair. There are several ways to detect and remove Arrow ransomware, and there is also a chance to restore part or even all encrypted files to their original state. Below we will describe in detail how to do this.

How to decrypt .arrow files
All files with the ‘.arrow’ extension are encrypted. Their contents cannot be unlocked simply by removing this extension or completely changing the filename. Unfortunately, as we already reported in this article, there is currently no way to decrypt files. The reason for this is the complexity of the encryption algorithm that the authors of Arrow virus use. In principle, this is what the attackers sought. But this does not mean that you have no choice and you need to pay a ransom for your files.
Never pay the ransom! Every security expert will tell you this over and over. Of course, there is a chance that by paying a ransom, the Arrow virus authors will allow you to unlock your files, but there is no guarantee. Moreover, you should understand that when you pay a ransom, you unknowingly push the attackers to create new, even more destructive viruses.
Do not forget that besides you, thousands more people around the world have lost their files, that is, you are not alone. Antivirus companies, security experts are working on something that will allow you to decrypt .Arrow files. Perhaps in the future an universal method will be developed that will allow all victims to unlock all their data.
Of course, as soon as a way to decrypt the files appears, we will post a message about this to this article or to our facebook account. Therefore, we recommend that you follow the updates.
How to restore .arrow files
As we wrote above, you cannot decrypt files encrypted with Arrow ransomware. But you can use a different way, there is a small chance to restore .Arrow files without decrypting them. Programs created for searching and recovering lost and deleted data can help you with this. We recommend you to use the following free programs: PhotoRec and ShadowExplorer. Two more things we want to say about. First, before restoring files, you must be 100% sure that there is no ransomware on the computer. We recommend using free malware removal tools that we examined in this article. Second, and what is very important! The less you use your computer after ransomware infection, the higher the chance that you will be able to recover encrypted files.
Recover .arrow files with ShadowExplorer
First of all, try to recover your files using a free tool called ShadowExplorer. This program will allow you to recover your files from Shadow Volume Copies. These copies are created automatically by the Windows OS when you work with your files. Unfortunately, very often, the virus automatically deletes all these copies and thus prevents the user from recovering encrypted files. Nevertheless, in some cases, the ransomware cannot delete all copies, and the user gets the opportunity to quickly restore all files. Therefore, our opinion, you should definitely try this method!
Visit the page linked below to download ShadowExplorer. Save it directly to your Windows Desktop.

Update: September 15, 2019
When the downloading process is finished, open a directory in which you saved it. Right click to ShadowExplorer-0.9-portable and select Extract all. Follow the prompts. Next please open the ShadowExplorerPortable folder as on the image below.
Double click ShadowExplorerPortable to launch it. You will see the a window as shown in the following example.
In top left corner, select a Drive where encrypted files are stored and a latest restore point similar to the one below (1 – drive, 2 – restore point).
On right panel look for a file that you want to recover, right click to it and select Export similar to the one below.
This video step-by-step guide will demonstrate How to recover encrypted files using Shadow Explorer.
Use PhotoRec to restore .arrow files
Another really working way to recover your encrypted files is to use a program named PhotoRec. It is created to recover deleted or lost files. Does the Arrow ransomware block this method? Fortunately, the ransomware cannot block this method of recovering the contents of encrypted files. The more you used (moved, deleted, modified) files before infection, the greater the chance that you will be able to recover them.
Download PhotoRec by clicking on the link below.

Update: March 1, 2018
Once the downloading process is done, open a directory in which you saved it. Right click to testdisk-7.0.win and select Extract all. Follow the prompts. Next please open the testdisk-7.0 folder as displayed in the following example.
Double click on qphotorec_win to run PhotoRec for Microsoft Windows. It will display a screen as displayed on the image below.
Select a drive to recover such as the one below.
You will see a list of available partitions. Choose a partition that holds encrypted personal files as shown in the figure below.
Click File Formats button and choose file types to recover. You can to enable or disable the restore of certain file types. When this is done, press OK button.
Next, press Browse button to choose where recovered files should be written, then click Search. We strongly recommend that you save the recovered files to an external drive.
Count of recovered files is updated in real time. All recovered photos, documents and music are written in a folder that you have selected on the previous step. You can to access the files even if the restore process is not finished.
When the recovery is complete, press on Quit button. Next, open the directory where restored personal files are stored. You will see a contents as shown below.
All restored documents, photos and music are written in recup_dir.1, recup_dir.2 … sub-directories. If you are looking for a specific file, then you can to sort your recovered files by extension and/or date/time.
This video step-by-step guide will demonstrate How to recover encrypted files using PhotoRec.
