How to remove Bhtw Ransomware and decrypt .bhtw files

0
Bhtw Ransomware is a new variant of the STOP/Djvu ransomware family that encrypts files and adds the .bhtw extension to their names. This way, after encryption file, for example 1.doc will get a suffix and will become 1.doc.bhtw. The ransomware is distributed via spam email containing infected attachments, fake software cracks, or by exploiting vulnerabilities in the operating system and installed programs. Once the ransomware infects a computer, it encrypts all popular file types, including videos, images, documents, audio files, and archives. After encryption, it generates a ransom note in the form of a text file named _readme.txt. The ransom note contains instructions on how to pay the ransom to get the decryption key.

How to remove Udaigen Ransomware and decrypt .jcrypt files

0
Udaigen Ransomware is a type of malware that encrypts files and demands payment for decryption. It adds its specific extension .jcrypt, to every file it encrypts. Unfortunately, there are no known decryption tools for Udaigen Ransomware at this time. The encryption method used by this ransomware is currently unknown. To prevent further encryption by Udaigen ransomware, it is essential to remove it from the operating system. However, removing the ransomware will not restore the compromised files. The only solution is to recover the files from a previously created backup stored in a different location. We highly recommend storing backups in multiple separate locations, such as remote servers or unplugged storage devices, to prevent permanent data loss. Malware creates ransom note ___RECOVER__FILES__.jcrypt.txt and displays pop-up window with information to contact the hackers.

How to remove Bhgr Ransomware and decrypt .bhgr files

0
Bhgr Ransomware is a file-encrypting virus and a variant of the STOP/Djvu ransomware family. It encrypts files and appends the .bhgr extension to their original filenames. It uses advanced RSA and AES encryption algorithms to lock files of infected PCs, making it impossible to unlock files without knowing the unique private decryption key generated by the computer. Unfortunately, at this time, there are no decryption tools available for Bhgr Ransomware. However, Emsisoft provides free ransomware decryption tools that may work with specific ransomware versions. Bhgr Ransomware generates a ransom note in the form of a text file named _readme.txt. The ransom note contains instructions on how to pay the ransom in exchange for a decryption key that can unlock the encrypted files.

How to remove Bhui Ransomware and decrypt .bhui files

0
Bhui Ransomware is a type of malware that encrypts files on a victim's computer and demands payment in exchange for a decryption key. Bhui ransomware is part of the STOP/Djvu ransomware family and is spread through malicious files disguised as freeware, key generators, and hacked games, which are commonly found on file-sharing and torrent sites. Once installed, Bhui encrypts all files on the victim’s computer, adding the .bhui extension to the filenames. For example, a file named 1.jpg gets renamed to 1.jpg.bhui, and 2.png becomes 2.png.bhui. Bhui ransomware encrypts files using a strong encryption algorithm called Salsa20. The encryption algorithm is complex and makes it difficult to decrypt files without the decryption key. In addition to file encryption, Bhui generates a ransom note, a text file called _readme.txt. The ransom note emphasizes that file decryption is only possible with the use of specific decryption software and a unique key.

How to fix PR_END_OF_FILE_ERROR in Mozilla Firefox

0
The PR_END_OF_FILE_ERROR is a Firefox-specific error that occurs when the browser can't establish a secure connection with a website. This error can be caused by several factors, including VPN or proxy connections, incorrect SSL settings in your browser, a corrupted Firefox profile, and overzealous security software. Another possible cause is an incorrect or unstable network connection. The error occurs when Firefox isn’t able to establish a secure connection to a site due to the browser’s “cipher suites” failing. In other words, it’s reached the end of the file containing the cipher suites and none have worked (hence the error name). It is generally harmless and more likely indicates an issue with your connection or browser. The PR_END_OF_FILE_ERROR only happens on Mozilla Firefox, which means you won’t see this in Safari, Chrome, Opera, or Edge. If you're experiencing the PR_END_OF_FILE_ERROR in Mozilla Firefox, there are several things you can try to fix it.

How to remove Ahtw Ransomware and decrypt .ahtw files

0
Ahtw Ransomware is a type of malware that encrypts files on a victim's computer and then demands payment in exchange for the decryption key. Once the ransomware infects a system, it can quickly encrypt files without the user's knowledge, making it difficult to detect the infection until it is too late. The ransomware is associated with the STOP/Djvu family and is often distributed alongside other malware, including RedLine or Vidar. Once the encryption process is complete, Ahtw Ransomware renames each encrypted file by adding the extension .ahtw to its name. The criminals behind Ahtw Ransomware demand a ransom of $980 in exchange for the key and decryptor, which they claim is the only way to decrypt the encrypted files. Ahtw ransomware creates a ransom note named _readme.txt in each affected directory. The ransom note provides details on how to reach out to the attackers and instructions for making a ransom payment.
