.Noos file extension is evidence that your computer has become a victim of ransomware. Other signs of infection is that these files have empty icons and they do not open in any of the programs you use. You are not the first to fall victim to this virus. This is confirmed by a message posted by the security expert on his Twitter account here.
This is not the first, and probably not the latest version of the same ransomware virus. To date, 169 versions of this virus have already been found. Almost every week, attackers release 2-3 new versions of the ransomware. If you have never heard of such computer viruses, here is what you need to know about them. Ransomware also know as File locker, Crypto virus, Filecoder is malware created to encrypt files on the victim’s computer. As a result of this attack, the files will be actually blocked, since they cannot be opened in any program. To decrypt them, the victim must pay a ransom to the attackers.
What is Noos ransomware
The Noos ransomware virus most often gets to the computer as part of other programs (freeware, cracked apps and games) that have been downloaded by the user from the Internet. After its start, the virus begins to encrypt files using a key that is individual for each computer. The virus 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. The virus 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 OS to function normally. Below we list the types of files that can be encrypted by the ransomware.
.re4, .snx, .syncdb, .sis, .wpw, .dbf, .webp, .wn, .xmmap, .m3u, .db0, .r3d, .vdf, .raw, .epk, .wma, .das, .rwl, .pptx, .sie, .xx, .srw, .hkdb, .wpl, .crw, .m4a, .bc7, .xlsx, .psd, .d3dbsp, .menu, .wp4, .esm, .docx, .hplg, .itdb, .xlsm, .xll, .sb, .mp4, .ptx, .wgz, .ybk, .vtf, .wp5, .crt, .odp, .dba, .vpk, .jpg, .wps, .y, .pdf, .svg, .jpeg, .zdb, .qic, .p7c, .mov, .x3f, .wmo, .rb, .accdb, .indd, .sum, .ltx, .bkf, .wp6, .blob, .itm, .hkx, .tor, .xlgc, .kdb, wallet, .tax, .forge, .wp7, .xlsm, .kf, .itl, .wmv, .desc, .pkpass, .yal, .erf, .zabw, .ff, .xxx, .webdoc, .pem, .js, .xlsb, .wri, .flv, .xml, .yml, .1, .3ds, .qdf, .wbm, .wmv, .wps, .wm, .1st, .odm, .p7b, .wbc, .xar, .2bp, .wpd, .rtf, .psk, .mef, .rgss3a, .iwd, .raf, .pst, .wma, .wbmp, .srf, .arw, .ibank, .css, .wb2, .p12, .rw2, .cr2, .lvl, .ai, .xyw, .big, .wpt, .rar, .ysp, .t12, .xf, .lrf, .ods, .ppt, .fos, .xdl, .z, .xls, .dcr, .pdd, .wbk, .xls, .wcf, .mdf, .avi, .wpa, .7z, .bik, .sidd, .xbdoc, .py, .zip, .sav, .orf, .t13, .bc6, .ncf, .z3d, .m2, .wdp, .png, .hvpl, .3fr, .bsa, .zif, .dng, .docm, .asset, .bar, .mpqge, .mcmeta, .zw, .xbplate, .cdr, .lbf, .w3x, .xmind, .xlsx, .pef, .map, .odb, .gho, .bkp, .cas, .dazip, .bay, .xwp, .icxs, .x, .pak, .txt, .gdb, .apk, .mlx, .xlk, .litemod, .odt, .arch00, .xyp, .ztmp, .cfr, .x3f, .mdb, .pptm, .sql, .rofl, .wot, .fsh, .zip, .0, .3dm, .slm, .zdc, .xy3, .wsh, .wmd, .wmf, .vcf, .mddata, .nrw, .fpk, .layout, .rim, .mdbackup, .wpb, .wpe, .wire, .wbz, .vpp_pc, .der
When the file is encrypted, ‘.Noos’ is added at the end of its name, that is, if you had a file of ‘document.doc’, then a file with the name ‘document.doc.noos’ 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.
Having carefully examined the contents of directories that contain encrypted files, you probably found a file named ‘_readme.txt’ or ‘_readme’, which for some reason is not encrypted. This file was created automatically by the virus, and contains a ransom request. To make sure you notice it, the authors of the virus added the symbol ‘_’ at the beginning of its name so that this file is shown first in the list of files. If you accidentally deleted this file, then you can find it in other directories where there is at least one encrypted file. An example of such a file is given below.

As we have already said, this virus is not the first in its series; more than 150 variants have already been released. 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 (otherwise how would you be on our site), indicates the complexity of the virus and the method that it uses to encrypt files. Nevertheless, you do not need to despair. There are several ways to find and remove Noos 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 remove Noos ransomware and restore encrypted files
If you encounter the malicious actions of this virus, and your files have been encrypted, then you need to remove the virus or be 100% sure that there is no virus on your computer, and then proceed to restore the files. Both the virus removal process and the file recovery process will take a lot of time, so do not believe the magical instructions that say that this can be done very quickly. We definitely recommend, even if for some reason one of the methods proposed below did not suit you, try another one and try all of them. Perhaps one of them will help you. Feel free to ask questions in the special section on our website or in the comments below. In addition, we want to add that all the programs that we recommend using in our instructions are free and verified by security experts. And the last, before proceeding with the instructions, we advise you to read it thoroughly carefully, and then print or open it on a tablet or smartphone to have it always at hand.

How to remove Noos ransomware
To remove the Noos virus, you will need several programs (so called malware removal tools), which we will consider below. You can use them in the same sequence as we gave, or in the order as you like. Perhaps you think that this virus can be removed manually by using some magic OS functions or by pressing a few keys. Probably a professional or computer specialist with great knowledge will be able to, but I recommend you use special utilities. They will do all the work for you, and most importantly they will prevent damage to system files that you might accidentally do. Of course, if you have an antivirus, you can use it first, but if it missed this ransomware, then your trust in it is greatly undermined.

How to decrypt .noos files
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 the 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! Any security expert will tell you this. Of course, there is a chance that by paying a ransom, the authors of the virus 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, secuity experts are working on something that will allow you to decrypt your files. So, for example, for previous versions of this virus, experts found a way that allows in some cases to decrypt encrypted 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 add a message about this to this article or to our facebook account. Therefore, we recommend that you follow the updates.
How to restore .noos files
As we wrote above, you cannot decrypt files encrypted with this virus. But you can use a different way, there is a small chance to restore files without decrypting them. Programs created for searching and recovering lost and deleted data can help you with this. We offer you to use the following free programs: PhotoRec and ShadowExplorer. Only two things that I want to say additionally. First, before restoring files, you must be 100% sure that there is no virus on the computer. We recommend using the malware removal tools that we examined in this article; another option is to remove the disk from the infected computer and connect it as an additional disk to another computer. Then check this disk for malware, and then proceed to restore files. 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.
Use shadow copies to recover .noos files
Now proceed to recover encrypted files. We hope you have already completed all the steps that we discussed above. First of all, try to recover your files using a free program called ShadowExplorer. This program will allow you to recover your files from Shadow Volume Copies. These copies are created automatically by the OS when you work with your files. Unfortunately, very often, the virus automatically deletes all these copies and thus prevents the user from recovering exnrypted 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 the latest version of ShadowExplorer for MS Windows. Save it on your MS Windows desktop.
Category: Security tools
Update: September 15, 2019
After downloading is done, 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.
Start the ShadowExplorer tool and then select the disk (1) and the date (2) that you wish to restore the shadow copy of file(s) encrypted by the Noos ransomware virus as shown in the following example.
Now navigate to the file or folder that you want to restore. When ready right-click on it and click ‘Export’ button like below.
Restore .noos files with PhotoRec
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 virus block this method? Fortunately, the virus cannot block it in any way. Why is this possible you ask. This is possible for the reason that when you delete files using the standard OS function, these files are not actually deleted. Just the Windows marks them as deleted and does not show them in the list of files. The program that we suggest you use, finds deleted files, including files that were deleted by the ransomware, and recovers them.
Download PhotoRec from the following link. Save it directly to your MS Windows Desktop.
Category: Security tools
Update: March 1, 2018
Once the download is complete, 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 on the image below.
Double click on qphotorec_win to run PhotoRec for Windows. It will open a screen like below.
Select a drive to recover like below.
You will see a list of available partitions. Choose a partition that holds encrypted photos, documents and music similar to the one below.
Press File Formats button and select file types to recover. You can to enable or disable the restore of certain file types. When this is complete, click OK button.
Next, click Browse button to select where recovered files should be written, then click Search.
Count of recovered files is updated in real time. All restored personal files are written in a folder that you have chosen on the previous step. You can to access the files even if the recovery process is not finished.
When the recovery is finished, click on Quit button. Next, open the directory where restored personal files are stored. You will see a contents as on the image below.
All recovered personal files are written in recup_dir.1, recup_dir.2 … sub-directories. If you’re looking for a specific file, then you can to sort your restored files by extension and/or date/time.
How to protect your machine from Noos ransomware
Most anti-virus programs can somehow protect your computer from ransomware. But since you are reading this, then probably this protection did not work. Therefore, we recommend using programs that are specifically designed to protect against ransomware attacks. One such program is HitmanPro.Alert. Besides the fact that this program can detect, block and remove ransomware, it can also reverse the changes made by ransomware virus.
Download HitmanPro Alert on your Windows Desktop from the link below.
