If you find out that Zenis Ransomware has sneaked onto your system, you can be sure that your files have been encrypted. This new malware threat may be just two weeks old and may not have infected lots of users yet, but you should not take it lightly for a second. This malware infection attacks your most important files to strike hard enough for you to want to pay the ransom fee. However, you should know that it is always risky to contact cyber crooks or transfer money to them. Unfortunately, it is possible that instead of the decryptor and the private key you would simply get infected with another dangerous threat. Although first this ransomware seemed to be undecryptable, a working free decryption tool may already be available on the net. Of course, it is not safe for inexperienced users to try to find it or use it, either. We recommend that you ask a friend or a professional to help you with it. If you want to restore your system first, though, you need to remove Zenis Ransomware from your PC. Please read our article to learn more about this dangerous threat.

It is possible to infect your computer with this vicious ransomware program if you have a remote desktop program like TeamViewer installed and it is not set up properly and securely enough. For example, you may use a weak password that can be cracked via social engineering or brute force attacks. In any case, if this is the case, cyber criminals can relatively easily gain access to your system and initiate such a horrendous attack in no time. Of course, losing your files in such a malicious attack could be part of your problem, because once such villains have access to your system, they can take control over anything really and even steal sensitive information. Please remember that you cannot delete Zenis Ransomware without the encryption being accomplished. So, make sure that your system is well protected.

You can also infect your system with this malware if you open a spam mail and try to see its attachment. This ransomware is also spread in spam e-mails disguised as a document or image attachment. Normally you would probably not open a fake mail; however, this spam could look totally authentic and even one concerning you. This spam may be about a speeding ticket you have not settled, a parcel that FedEx failed to deliver to your address, or any issues with your credit card details. This is a mail that you would not necessarily consider as a spam at first sight. Once you open it, it may instruct you to view the attached file for more detailed information or proof. However, this is the point of no return because after you click to see this file, you will not be able to delete Zenis Ransomware without the possibility of losing your files to encryption.

This ransomware uses the AES encryption algorithm to take your files hostage. It targets at least 200 file extensions, including .txt, .doc, .docx, .xls, .xlsx, .ppt, .pptx, .odt, .jpeg, .png, .csv, .sql, .mdb, .sln, .php, .asp, .aspx, .html, .xml, .psd, .sql, .mp4, .7z, .rar, .m4a, .wma, .avi, .wmv, .csv, .d3dbsp, .zip, .sie, .sum, .ibank, .t13, .t12, .qdf, .gdb, .tax, .pkpass, .bc6, .bc7, .bkp, .qic, .bkf, .sidn, .sidd, .mddata, and .itl. As you can see, you may lose all your videos, images, audios, MS Office documents, archives, and more. It seems that this malware infection also deletes backup files and disables main system processes, such as Task Manager.

The ransom note is called "Zenis-Instructions.html" and it is dropped in every folder where files have been affected by this threat. This note instructs you to send an email with this ransom note file and an encrypted file that is not larger than 2MB to both TheZenis@Tutanota.com and TheZems@MailFence.com. In case you do not get a reply after six hours, you are supposed to submit your request again to TheZenis@Protonmail.com and TheZenis@Mail2Tor.com. After you check your decrypted file and send a confirmation mail, you will get instructions about the payment in a new mail. We have no information regarding the amount of the ransom fee but we do not advise you to pay anyway. We recommend that you remove Zenis Ransomware ASAP.

If you are ready to act, you can use our guide below. First of all, you should restart your computer in Safe Mode since the main process are blocked so you may not be able to remove this ransomware program without leaving leftovers. Then, you can try to recover your files using the free decryptor that should be available now on the net. If you do not think you can protect your computer against such threats in the future, we suggest that you install a reliable anti-malware program, such as SpyHunter as soon as possible.
