What is CryptPKO?

CryptPKO is a dangerous ransomware, which can easily cause lots of issues and huge money losses. We say so because this threat is capable of encrypting important victim’s files and then start asking to pay a ransom in exchange for their decryption. You may be forced to pay from $100 to $500 when having this virus on your Windows computer. Typically, this payment should be made in bitcoins, so if you don’t have them in your e-wallet, you will have to get them at first. That’s why you should always think about the prevention of such viruses and also the protection of your important files. If you need a tool that could help you to avoid infiltration of CryptPKO virus and similar ransomwares (Cryptolocker, CTB Locker, Cryptowall, etc.), you should think about Reimage or other reputable anti-spyware. In addition, you should try to protect your important files like business documents, study-related files, pictures, art, music and similar files by making their extra copies. If you want to know more about that, check this post: Why do I need backup and what options do I have for that?

As soon as CryptPKO ransomware infects the system, it scans it and blocks files with 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. Typically, it encrypts these files with the help of asymmetric encryption, what means that there is no chance to guess the code that is needed for unlocking affected files. In addition, this threat starts showing a warning message that is asking to pay a ransom. We don’t recommend making this payment because there is no guarantee that this will help you to get the decryption key. For restoring your files, you should try R-Studio or Photorec that are free.

How can I get infected with CryptPKO?

This ransomware has been spread with a help of fake email messages that are trying to fool PC users into downloading their malicious attachments. Emails that you should stay away from include messages from huge companies (Amazon, ebay, etc.), financial institutions and governmental authorities. If you want to be sure that you are not dealing with hackers, make sure you check the sender. If the email address looks suspicious, delete the message because it is trying to infect your computer with CryptPKO. In addition, you should pay attention to spelling and typo mistakes. Hackers have never been good at that. If you think that you are dealing with this ransomware at the moment, you should waste no time and scan your computer with an updated anti-spyware. You can use one of these tools that are given down below to remove it from the system.

How to remove CryptPKO virus?

If you want to restore connection to your files, you should follow these steps. Please, do NOT pay a fine because this doesn’t guarantee that you will receive a key required for files’ decryption.

Also, we highly recommend thinking about the prevention of such infections. For that you can use previously mentioned programs. Besides, don’t forget to think about the immunity of your files and backup. For that you can use USB external hard drives, CDs, DVDs, or simply rely on online backups, such as Google Drive, Dropbox, Flickr and other solutions.
