Malware may reinstall itself multiple times if you don't delete its core files. This may require tracking down dozens of files in different locations.
We recommend downloading Advanced System Repair to eradicate Malware for you (it should cut down the time to about 15 minutes).
What is Vurten ransomware? And how does it implement its attack?
Vurten ransomware is another file-encrypting threat discovered in the first week of April 2018. This malware makes use of the AES encryption algorithm in locking the file it targets. Its encrypted files can be distinguished by an extension is uses which is “.improved”. According to security experts, this ransomware most likely targets English-speaking users as its ransom note is written in English and it hasn’t been translated into other languages yet.
As soon as its malicious payload is executed, Vurten ransomware will start scanning the system to look for certain files to encrypt. This crypto-malware will most likely target files with the following extensions:
.3dm, .3g2, .3gp, .7zip, .aaf, .accdb, .aep, .aepx, .aet, .ai, .aif, .as, .as3, .asf, .asp, .asx, .avi, .bmp, .c, .class, .cpp, .cs, .csv, .dat, .db, .dbf, .doc, .docb, .docm, .docx, .dot, .dotm, .dotx, .dwg, .dxf, .efx, .eps, .fla, .flv, .gif, .h, .idml, .iff, .indb, .indd, .indl, .indt, .inx, .jar, .java, .jpeg, .jpg, .js, .m3u, .m3u8, .m4u, .max, .mdb, .mid, .mkv, .mov, .mp3, .mp4, .mpa, .mpeg, .mpg, .msg, .pdb, .pdf, .php, .plb, .pmd, .png, .pot, .potm, .potx, .ppam, .ppj, .pps, .ppsm, .ppsx, .ppt, .pptm, .pptx, .prel, .prproj, .ps, .psd, .py, .ra, .rar, .raw, .rb, .rtf, .sdf, .sdf, .ses, .sldm, .sldx, .sql, .svg, .swf, .tif, .txt, .vcf, .vob, .wav, .wma, .wmv, .wpd, .wps, .xla, .xlam, .xll, .xlm, .xls, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .xml, .xqx, .xqx, .zip
Vurten ransomware runs scripts using Command Prompt to root itself into the operating system and apply the AES 256 cryptography in locking the files. Consequently, it will append the .improved extension to mark the files it has managed to encrypt. After that, it drops a file name “UNCRYPT.README.txt” which contains the following context:
“Your entire network sensetive data was encrypted with our strong algorithm.
To recover your data send $10000 to the bitcoin address: 1Ln9RxSRuDqqFhCTuqBPBKRMeyhVhRaUG4
If you do not send money within 7 days, payment will be increased double.
After payment, you will receive decryption software.
The cyber crooks behind this cryptovirus are quite modest as they demand a huge amount of ransom worth $10000 which is so far the highest demanded the ransom to date. This insane amount is something you shouldn’t give to these crooks as it will only encourage them to develop more similar threats. The best way to deal with this threat is by terminating it from the system as soon as possible.
How does Vurten ransomware spread its malicious file(s)?
Vurten ransomware uses the old but gold distribution method in spreading its malicious files which is via spam emails. These days, cyber crooks rely on spam bots in spreading deceptive emails from well-known groups or companies to trick users into opening them and downloading the attached file which is used to install the crypto-malware into the system.

Try to recover your encrypted files using the Shadow Volume copies
Restoring your encrypted files using Windows’ Previous Versions feature will only be effective if Vurten ransomware hasn’t deleted the shadow copies of your files. But still, this is one of the best and free methods there is, so it’s definitely worth a shot.
To restore the encrypted file, right-click on it and select Properties, a new window will pop-up, then proceed to Previous Versions. It will load the file’s previous version before it was modified. After it loads, select any of the previous versions displayed on the list like the one in the illustration below. And then click the Restore button.
After you’ve covered the steps provided above, you need to continue the removal process of Vurten ransomware with the help of a reliable program like Advanced System Repair. How? Follow the advanced removal steps below.
Perform a full system scan using asr. To do so, follow these steps:
- Turn on your computer. If it’s already on, you have to reboot
- After that, the BIOS screen will be displayed, but if Windows pops up instead, reboot your computer and try again. Once you’re on the BIOS screen, repeat pressing F8, by doing so the Advanced Option shows up.
- To navigate the Advanced Option use the arrow keys and select Safe Mode with Networking then hit
- Windows will now load the SafeMode with Networking.
- Press and hold both R key and Windows key.
- If done correctly, the Windows Run Box will show up.
- Type in the URL address, https://www.fixmypcfree.com/download.php?asr in the Run dialog box and then tap Enter or click OK.
