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.

How to remove TmrCrypt0r Ransomware and decrypt .TmrCrypt0r files

0
TmrCrypt0r is a ransomware virus that belongs to the Xorist ransomware family. It encrypts important personal files, such as photos, videos, and documents, and adds the .TMRCRYPT0R extension to every file's name. Once the files are encrypted, they become inaccessible and cannot be opened without decryption. After encrypting the files, TmrCrypt0r creates a ransom note that provides payment information and the threat of what will happen if payment is not made. The ransom note is usually found in a text file or a pop-up window and prompts the victims to pay a ransom in exchange for the decryption key.

How to remove MiniMe Ransomware and decrypt .minime files

MiniMe Ransomware is a type of malware that encrypts files on a victim's computer and demands payment in exchange for the decryption key. It is a relatively new ransomware strain that was first discovered in 2023. The ransomware is, probably named after the popular movie character "Mini-Me" from the Austin Powers series. MiniMe Ransomware adds the .minime extension to encrypted files. For example, a file named example.doc would be renamed to example.doc.minime after encryption. MiniMe Ransomware uses a combination of RSA and AES encryption to encrypt files on a victim's computer. MiniMe Ransomware creates a ransom note named read_it.txt in each folder that contains encrypted files. The ransom note contains instructions on how to pay the ransom and obtain the decryption key.

How to remove Ahgr Ransomware and decrypt .ahgr files

0
Ahgr Ransomware is a type of malware that encrypts files on a victim's computer and demands a ransom for their release. Ahgr is part of the Djvu ransomware family and encrypts files by adding the .ahgr extension to their names. Ahgr ransomware uses the Salsa20 encryption algorithm, which provides an overwhelming amount of possible decryption keys, making it difficult to brute force the 78-digit number of keys. When Ahgr ransomware infects a computer, it creates a ransom note as a text file named _readme.txt in every folder that the ransomware has encrypted files. The note assures victims that they can retrieve all their files and claims that various files, including pictures, databases, documents, and other important data, have been encrypted using a robust encryption.
