DC Virus Files of Ransomware — How to remove virus?

What is known about the Dcvirus?

The scheme of renaming is the following: [contact email][victim\’s ID].DC. As a part of encryption, a file named, for example, “report.docx” will be turned into “report.docx.[931AS12EK3].[].DC”.

In every folder that contains the encrypted files, a FILES ENCRYPTED.txt file will appear. It is a ransom money note. It contains information on the ways of contacting the racketeers and some other remarks. The ransom note usually contains instructions on how to purchase the decryption tool from the ransomware developers. That is basically the scheme of the malefaction.

Name	Dc Virus
Ransomware family¹	Dharma ransomware
Extension	.[contact email][victim\’s ID].DC
Ransomware note	FILES ENCRYPTED.txt
Detection²	MSIL/Filecoder.LokiLocker.C, Ransom.LokiLocker, PWS:Win32/Ymacco.AA0A
Symptoms	Your files (photos, videos, documents) get a .[contact email][victim\’s ID].DC extension and you can’t open them.
Fix Tool	GridinSoft Anti-MalwareSee If Your System Has Been Affected by Dc virus

In the image below, you can see what a folder with files encrypted by the Dc looks like. Each filename has the “.[contact email][victim\’s ID].DC” extension appended to it.

$Dc Virus - encrypted .[contact email][victim\'s ID].DC files$

That is how encrypted “.[contact email][victim\’s ID].DC” files look.

How did Dc ransomware end up on my PC?

There are currently three most popular ways for malefactors to have the Dc virus planted in your system. These are email spam, Trojan infiltration and peer-to-peer networks.

If you open your mailbox and see emails that look just like notifications from utility services providers, delivery agencies like FedEx, web-access providers, and whatnot, but whose “from” field is unknown to you, be wary of opening those emails. They are most likely to have a viral item attached to them. So it is even riskier to download any attachments that come with letters like these.

Another thing the hackers might try is a Trojan virus model³. A Trojan is a program that gets into your PC pretending to be something else. Imagine, you download an installer for some program you want or an update for some software. But what is unboxed turns out to be a harmful agent that encrypts your data. Since the installation wizard can have any title and any icon, you’d better be sure that you can trust the resource of the files you’re downloading. The optimal thing is to trust the software companies’ official websites.

As for the peer file transfer protocols like torrent trackers or eMule, the threat is that they are even more trust-based than the rest of the Internet. You can never guess what you download until you get it. Our suggestion is that you use trustworthy websites. Also, it is reasonable to scan the folder containing the downloaded items with the antivirus as soon as the downloading is done.

How do I get rid of the Dc virus?

Often racketeers would decode several of your files to prove that they really have the decryption program. As Dc virus is a relatively new ransomware, anti-malware designers have not yet found a method to reverse its work. However, the decryption tools are frequently upgraded, so the effective countermeasure may soon arrive.

Sure thing, if the hackers succeed in encrypting someone’s essential files, the desperate person will most likely comply with their demands. Nevertheless, paying to criminals does not necessarily mean that you’re getting your data back. It is still risky. After getting the money, the racketeers may send a wrong decryption code to the victim. There were reports of racketeers just disappearing after getting the money without even writing back.

The optimal safety measure against ransomware is to have aan OS restore point or the copies of your essential files in the cloud disk or at least on an external storage. Surely, that might be insufficient. Your most crucial thing could be that file you were working upon when it all went down. But at least it is something. It is also reasonable to scan your PC for viruses with the anti-malware utility after the OS restoration.

There are other ransomware products, besides Dc, that work similarly. For instance, Zaqi, Qqqw, Maak, and some others. The two major differences between them and the Dc are the ransom amount and the method of encryption. The rest is the same: files become inaccessible, their extensions altered, ransom notes emerge in each directory containing encoded files.

Some fortunate people were able to decode the arrested files with the aid of the free software provided by anti-ransomware specialists. Sometimes the racketeers accidentally send the decoding key to the wronged in the ransom note. Such an epic fail allows the victim to restore the files. But of course, one should never rely on such a chance. Remember, ransomware is a tamperers’ instrument to pull the money out of their victims.

How to avoid ransomware attack?

You can armour yourself from ransomware infiltration in three easy steps:

Never open any letters from unknown senders with strange addresses, or with content that has likely no connection to something you are expecting (how can you win in a money prize draw without even taking part in it?). If the email subject is more or less something you are waiting for, scrutinize all elements of the dubious email carefully. A hoax email will always contain mistakes.
Avoid using cracked or untrusted programs. Trojans are often spreaded as a part of cracked software, most likely as a “patch” which prevents the license check. Understandably, untrusted programs are difficult to tell from reliable ones, because trojans sometimes have the functionality you need. You can try to find information on this program on the anti-malware forums, but the best solution is not to use such software.
And finally, to be sure about the safety of the objects you downloaded, scan them with GridinSoft Anti-Malware. This software will be a perfect armor for your system.

There is no better way to recognize, remove and prevent ransomware than to use an anti-malware software from GridinSoft">⁵.

FAQ

🤔 Is it possible to open “.[contact email][victim\’s ID].DC” files?

There’s no way to do it, unless the files “.[contact email][victim\’s ID].DC” files are decrypted.

🤔 I really need to decrypt those “.[contact email][victim\’s ID].DC” files ASAP. How can I do that?

It’s good if you have fаr-sightedly saved copies of these important files elsewhere. If not, there is still a function of System Restore but it needs a Restore Point to be previously saved. There are other ways to beat ransomware, but they take time.

🤔 You have advised using GridinSoft Anti-Malware to get rid of the Dc virus. Does it mean that all my files, currently encrypted, will be removed too?

Absolutely not! The encrypted files are not harmful, so they won’t be deleted.

GridinSoft Anti-Malware only deals with actual viruses. The malware that has infected your device is probably still active and running scans periodically to arrest any new files you might create on your PC after the attack. As it has been mentioned above, the Dc ransomware comes with the company. It installs backdoors and keyloggers that can take your account passwords by trespass and provide hackers with easy access to your PC in the future.

🤔 What should I do if the Dc virus has blocked my PC and I can’t get the activation code.

If that happened, you need to prepare a memory stick with a pre-installed Trojan Killer. Use Safe Mode to do the cleaning. You see, the ransomware starts automatically as the system boots and encodes any new files created or imported into your system. To stop this function – use Safe Mode, which allows only the vital programs to run upon system start. Consider reading our manual on running Windows in Safe Mode.

🤔 And what should I do now?

Some of the encrypted files can be found elsewhere.

If you exchanged your important files via email, you could still download them from your online mail server.
You might have shared photographs or videos with your friends or family members. Just ask them to send those images back to you.
If you have initially downloaded any of your files from the Internet, you can try doing it again.
Your messengers, social networks pages, and cloud storage might have all those files as well.
Maybe you still have the needed files on your old PC, a notebook, phone, memory stick, etc.

HINT: You can employ file recovery programs⁶ to retrieve your lost information since ransomware encodes the copies of your files, removing the original ones. In the video below, you can see how to use PhotoRec for such a recovery, but remember: you can do it only after you eradicate the ransomware itself with an anti-malware program.

Also, you can contact the following governmental fraud and scam sites to report this attack:

In the United States: On Guard Online;
In Canada: Canadian Anti-Fraud Centre;
In the United Kingdom: Action Fraud;
In Australia: SCAMwatch;
In New Zealand: Consumer Affairs Scams;
In France: Agence nationale de la sécurité des systèmes d’information;
In Germany: Bundesamt für Sicherheit in der Informationstechnik;
In Ireland: An Garda Síochána;

To report the attack, you can contact local executive boards. For instance, if you live in USA, you can have a talk with FBI Local field office, IC3 or Secret Service.
