WINCRYPTO Virus Files of Ransomware — How to remove virus?

The Wincrypto virus falls under the ransomware type of infection. Ransomware of such sort encrypts all user’s data on the PC (photos, documents, excel tables, music, videos, etc) and adds its extra extension to every file, creating the README WINCRYPTO.txt text files in every folder which contains the encrypted files.

What is known about the Wincryptovirus?

☝️ A scientifically accurate description for the Wincrypto would be “a ransomware-type infection”.

Wincrypto will append its own .wincrypto extension to the title of each encrypted file. For example, an image entitled “photo.jpg” will be renamed to “photo.jpg.wincrypto”. Likewise, the Excel table with the name “table.xlsx” will become “table.xlsx.wincrypto”, and so forth.

In each directory with the encrypted files, a README WINCRYPTO.txt notebook file will be found. It is a ransom money note. It contains information on the ways of paying the ransom and some other information. The ransom note most probably contains instructions on how to purchase the decryption tool from the Wincrypto developers. That is pretty much the scheme of the felony.

How did my machine catch Wincrypto ransomware?

There are plenty of possible ways of ransomware injection.

Nowadays, there are three most popular ways for criminals to have the Wincrypto virus settled in your digital environment. These are email spam, Trojan introduction and peer-to-peer file transfer.

If you access your inbox and see letters that look like familiar notifications from utility services providers, postal agencies like FedEx, web-access providers, and whatnot, but whose sender is strange to you, be wary of opening those emails. They are most likely to have a malware item attached to them. So it is even riskier to open any attachments that come with letters like these.

As for the peer file transfer protocols like torrents 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. So you’d better be using trustworthy websites. Also, it is a good idea to scan the folder containing the downloaded objects with the anti-malware utility as soon as the downloading is complete.

How do I get rid of the Wincrypto virus?

It is important to note that besides encrypting your files, the Wincrypto virus will probably install the Azorult Spyware on your computer to seize your credentials to various accounts (including cryptocurrency wallets). That program can extract your credentials from your browser’s auto-filling cardfile.

Often tamperers would decrypt several of your files to prove that they do have the decryption tool. As Wincrypto virus is a relatively new ransomware, anti-malware designers have not yet found a way to reverse its work. Nevertheless, the anti-ransomware instruments are frequently upgraded, so the effective countermeasure may soon be available.

Of course, if the tamperers succeed in encoding someone’s essential data, the desperate person will most likely comply with their demands. Despite that, paying to criminals gives no guarantee that you’re getting your files back. It is still risky. After getting the money, the racketeers may deliver a wrong decryption code to the injured party. There were reports about malefactors just vanishing after getting the ransom without even writing back.

The best solution against ransomware is to have a system restore point or the copies of your essential files in the cloud drive or at least on an external disk. Obviously, that might be not enough. Your most crucial thing could be that file you were working upon when it all started. Nevertheless, it is something. It is also advisable to scan your PC for viruses with the antivirus program after the OS is rolled back.

There are other ransomware products, besides Wincrypto, that work similarly. For instance, Blue, Khonsari, Yjqs, and some others. The two basic differences between them and the Wincrypto are the ransom amount and the method of encryption. The rest is the same: files become inaccessible, their extensions changed, ransom notes appear in each folder containing encrypted files.

Some fortunate people were able to decrypt the arrested files with the aid of the free tools provided by anti-ransomware experts. Sometimes the racketeers mistakenly send the decoding code to the wronged in the ransom readme. Such an epic fail allows the victim to restore the files. But of course, one should never rely on such a chance. Make no mistake, ransomware is a bandits’ tool to pull the money out of their victims.

How сan I avert ransomware injection?

Wincrypto ransomware doesn’t have a superpower, neither does any similar malware.

You can armour your PC from ransomware attack within three easy steps:

  • Ignore any emails from unknown mailers with unknown addresses, or with content that has likely no connection to something you are expecting (can you win in a lottery without participating in it?). If the email subject is more or less something you are expecting, check all elements of the questionable letter with caution. A hoax email will surely contain a mistake.
  • Avoid using cracked or unknown programs. Trojan viruses are often distributed as an element of cracked software, most likely under the guise of “patch” preventing the license check. But untrusted programs are very hard to tell from reliable software, because trojans may also have the functionality you need. Try to find information about this program on the anti-malware forums, but the best solution is not to use such software.

FAQ

🤔 How can I open “.wincrypto” files?Are the “.wincrypto” files accessible?

Unfortunately, no. You need to decipher the “.wincrypto” files first. Then you will be able to open them.

🤔 The encrypted files are very important to me. How can I decrypt them quickly?

If the “.wincrypto” files contain some really important information, then you probably have them backed up. Otherwise, you might try to employ System Restore. The only question is whether you have saved any Restore Points that would be helpful now. The rest of the methods require patience.

🤔 What should I do if the Wincrypto malware has blocked my PC and I can’t get the activation key.

🤔 And what should I do now?

Many of the blocked files might still be at your disposal

  • If you sent or received your important files via email, you could still download them from your online mailbox.
  • You might have shared images or videos with your friends or family members. Just ask them to send those images back to you.
  • If you have initially got any of your files from the Internet, you can try doing it again.
  • Your messengers, social media pages, and cloud storage might have all those files as well.
  • It might be that you still have the needed files on your old computer, a laptop, phone, memory stick, etc.

HINT: You can employ data recovery utilities4 to retrieve your lost information since ransomware encrypts the copies of your files, removing the authentic ones. In the tutorial below, you can learn how to recover your files with PhotoRec, but be advised: you won’t be able to do it before you remove the ransomware itself with an anti-malware program.

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

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.
