Dont_Worry ransomware removal instructions

What is Dont_Worry?

Discovered by MalwareHunterTeam, Dont_Worry is a ransomware-type virus that stealthily infiltrates the system and encrypts most stored files. During the process, Dont_Worry appends filenames with the ".UPS-[random_digits/letters]" extension. For instance, "sample.jpg" might be renamed to a filename such as "sample.jpg.UPS-04a72efc45a7f985". Compromised data immediately becomes unusable. After successful encryption, Dont_Worry generates a text file ("Dont_Worry.txt") and places a copy in all existing folders.

The new file contains a message informing users of the encryption and encouraging them to contact Dont_Worry's developers via an email address provided. Note that all text is in Russian. Therefore, it is safe to assume that developers are either Russian or target users who live in this country. It is currently unknown which cryptography (symmetric or asymmetric) Dont_Worry employs. In any case, a unique key (generated individually for each victim) is necessary to restore data. Developers hide all keys on a remote server. After contacting these people (not recommended), users are encouraged to pay a ransom for release of their keys. The cost is also unknown (this is not provided via email), however, these ransoms typically fluctuate between $500 and $1500 in Bitcoins or another cryptocurrency. No matter what the cost, do not pay. Ransomware developers often ignore victims, once payments are submitted. Therefore, paying does not guarantee that your files will be decrypted - this will deliver no positive result and you will simply be scammed. You are strongly advised to ignore all requests to contact these people or submit any payments. Unfortunately, there are no tools capable of decrypting data compromised by Dont_Worry free of charge. There is only one solution: to restore everything from a backup.

Dont_Worry is regular ransomware and thus shares many similarities with JosepCrypt, PGPSnippet, RAPID RANSOMWARE V3, and others. Although these viruses are developed by different cyber criminals, their behavior is identical - all encrypt data and make ransom demands. There typically are just two major differences: size of ransom and type of encryption algorithm used. Unfortunately, most employ cryptographies (e.g., RSA, AES, and similar) that generate unique decryption keys. Therefore, unless the malware is not fully developed or has certain bugs/flaws, restoring data manually without involvement of developers (contacting these people is not recommended) is impossible. These viruses present a strong case for maintaining regular data backups, however, it is very important to store them on an unplugged storage device (e.g., external hard drive, Flash drive or similar) or a remote server (such as Cloud). If not, backups are encrypted with regular data.

How did ransomware infect my computer?

To proliferate ransomware, developers employ spam emails (malicious attachments), peer-to-peer (P2P) networks, unofficial download sources, fake software updaters, and (in some cases) trojans. Malicious attachments typically come in the format of JavaScript files or MS Office documents. Once opened, these files stealthily download and install malware. P2P networks (torrents, eMule and similar) and other third party download sources (freeware download websites, free file hosting sites, etc.) present malicious executables as legitimate software. In this way, many users are tricked into downloading and installing malware. Fake updaters infiltrate malware by exploiting outdated software bugs/flaws or simply downloading and installing it rather than updates. Trojans are probably the simplest - most open "backdoors" for other viruses to infiltrate the system.

Threat Summary:
NameDont_Worry virus
Threat TypeRansomware, Crypto Virus, Files locker
SymptomsCan't open files stored on your computer, previously functional files now have a different extension, for example my.docx.locked. A ransom demanding message is displayed on your desktop. Cyber criminals are asking to pay a ransom (usually in bitcoins) to unlock your files.
Distribution methodsInfected email attachments (macros), torrent websites, malicious ads.
DamageAll files are encrypted and cannot be opened without paying a ransom. Additional password stealing trojans and malware infections can be installed together with a ransomware infection.

How to protect yourself from ransomware infections?

The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. Therefore, pay close attention when browsing the Internet. Think twice before downloading/opening email attachments. If the file seems irrelevant or has been received from a suspicious/unrecognizable email address, it should not be opened and the email should be deleted immediately. Furthermore, we strongly advise you to download your applications from official sources only, using direct download links. Third party downloaders/installers often include rogue apps, and thus should never be used. The same applies to updating software. Keep installed applications up-to-date. To achieve this, however, use only implemented update functions or tools provided by the official developer. Have a reputable anti-virus/anti-spyware suite installed and running.

5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the Dont_Worry ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Dont_Worry ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Dont_Worry are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

Restoring files encrypted by CryptoDefense

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by Dont_Worry, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as Dont_Worry ransomware.

Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.

Controll Folder Access

Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.

HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
