Another CryptoWall/ Crowti ransomware message:

It is normal because the files' names, as well as the data in your files have been encrypted.
Congratulations!!! You have become a part of large community CryptoWall.
If you are reading this text that means that the software CryptoWall has removed from your computer…..
What is encryption?
Encryption is a reversible transformation of information in order to conceal it from unauthorized persons but providing at the same time access to it for authorized users. To become an authorized user and make the process truly reversible i.e. to be able to decrypt your files you need to have a special private key.
In addition to the private key you need the decryption software with which you can decrypt your files and return everything in its place.
I almost understood but what do I have to do?
The first thing you should do is to read the instructions to the end…..

When Crowti virus affects the machine, your files may be changed, renamed with ransom characters or marked with a different extension. In simple words, this virus affects your files and makes them useless, un-openable. This is the main indication besides the direct ransom-demanding message that shows up on the screen.

You need to remove Crowti virus, no matter how important your files are to you. It is possible to recover them later, but you need to eliminate malware as soon as possible, to avoid crucial damage to your computer. This threat has many more functionalities like altering system settings or disabling programs, functions. This is one of the oldest variants of ransomware that may have tons of versions.

Crowti ransomware can infect the machine, install programs, other malware, encrypt files and make them impossible to decrypt unless you pay for the tool. This virus also deletes Shadow Volume Copies, backups and databases or archives, so react to the infection as soon as possible until your computer is damaged permanently.

Crowti malwareCrowti virus is the virus that has Ransom:Win32/Crowti detection name. Crowti virus is a seriously dangerous ransomware, which is very similar to other ransomware threats. As soon as it gets inside the PC system, it checks what is kept on it and blocks all files that have such extensions: 3fr, accdb, ai, arw, bay, cdr, cer, cr2, crt, crw, dbf, dcr, der, dng, doc, docm, docx, dwg, dxf, dxg, eps, erf, indd, jpe, jpg, kdc, mdb, mdf, mef, mrw, nef, nrw, odb, odm, odp, ods, odt, orf, p12, p7b, p7c, pdd, pef, pem, pfx, ppt, pptm, pptx, psd, pst, ptx, r3d, raf, raw, rtf, rw2, rwl, srf, srw, wb2, wpd, wps, xlk, xls, xlsb, xlsm, xlsx. You may ask 'why?'. The answer is very simple – this virus seeks to make its victims pay a predetermined ransom for unblocking locked files.

Unfortunately, there is no guarantee that making this Crowti ransomware payment will help you recover connection to your affected files.[2] That's why we highly recommend people, enterprise, and home users, to make sure that they have made alternate copies of their important files. They can use Cloud storage technologies, Dropbox, Flash Drive, or even CDs for that.

In addition, you should always keep your anti-spyware up-to-date in order to prevent infiltration of this virus. You can avoid this infiltration and keep yourself from performing Crowti virus removal in the first place if you keep the machine virus-free properly.

If Crowti virus has already started showing you a warning that is filled with specific instructions explaining how you can unlock your files (it usually requires making a payment of $100, $200 or even $500 in bitcoins), you should waste no time and scan your computer with updated anti-spyware. It will help you to remove this and other cyber threats from the system.

Crowti ransom-demanding virusCrowti ransomware is a cryptovirus that demands Bitcoin payments with scary messages about the hacker access on the system.

Ransomware delivery methods

Just like any other ransomware threat, this virus is spread using several misleading techniques. You can easily fall into downloading this virus to your computer by clicking on fake pop-up notification offering you to update your Flash Player, Java, download manager or similar program.

In addition, spam campaigns have also been actively used when spreading this virus around. So, you should be very careful with every email that looks suspicious and actively asks you to download its attachment. According to our PC security experts[,[3] you should stay away from such and similar attachments: VOICEXXXX.scr, IncomingFaxXXXX.exe, info_XXXX.pdf.exe, etc. You need to delete any suspicious emails immediately after receiving them.

If you have already been tricked into downloading any of these attachments to your computer, you should waste no time and scan it with the reputable anti-spyware. It will help you to remove all malware and viruses, including the file-locking virus. If you have already received a warning asking you to pay for decrypting your blocked files, you shouldn't pay the ransom because you may be left with nothing. Instead of that, follow these steps and remove this threat.

Ways to remove Crowti virus from the machine completely

In order to prevent the appearance of Crowti virus, you should ignore all suspiciously-looking mails and ignore every ad that offers you to update your Flash, Java, and similar programs. In addition, make sure you scan your PC with a reputable anti-spyware if your PC is already affected by this ransomware. For that you can use FortectIntego or SpyHunter 5Combo Cleaner, Malwarebytes. If you can't launch any of these programs and there is no luck, try:

  1. Rebooting you infected PC to Safe mode with networking to disable the virus

Guide which is presented above is supposed to help you remove Crowti from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by security experts.

If your files are encrypted by Crowti, you can use several methods to restore them:

Rely on file restoring software

Data Recovery Pro is the program that can help with lost or encrypted files

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Crowti ransomware;
  • Restore them.

Windows Previous Versions can recover Crowti virus encoded files

Try Windows Previous Versions if you enabled System Restore before

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

ShadowExplorer – alternate solution for file backups

There is no tool for Crowti virus

How to prevent from getting ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
