How to remove Porn Ransomware and decrypt .porn files

0
Porn is classified as a ransomware infection that targets encryption of personal data. Files like photos, documents, music, and videos are most likely to be under the scope of encryption by Porn Ransomware. To differ encrypted files from regular ones, developers assign the .porn extension to each compromised sample. For instance, a file like 1.pdf will change to 1.pdf.porn and reset its original icon. After this, the virus starts demanding the so-called ransom to recover your data. This information can be seen in a featured pop-up window or text note called RECUPERAR__.porn.txt. Inside of this note and pop-up window, cybercriminals display the number of files they have decrypted. To erase the assigned ciphers, Porn developers ask victims to send 1 BTC to the attached crypto address and e-mail them with the transaction ID afterwards. Unfortunately, not many victims can afford to pay the price of 1 BTC (42,000 USD).

How to remove BlackByte Ransomware and decrypt .blackbyte files

0
BlackByte is the name of a data-locker that encrypts files stored on a device. Such malware is more known as ransomware because it extorts money from victims for the recovery of data. Even though BlackByte is new and little observed, there are enough details to differ it from other infections. One of them is the .blackbyte extension that is appended to each encrypted file. For instance, a piece like 1.pdf will change its extension to 1.pdf.blackbyte and reset the original icon. The next step after encrypting all available data is ransom note creation. BlackByte generates the BlackByte_restoremyfiles.hta file, which displays recovery details. Within, victims are instructed to contact cyber criminals by e-mail. This action is mandatory to receive further instructions on how to purchase a file decryptor. This decryptor is unique and held only by cybercriminals. The price of ransom can vary from person to person reaching hundreds of dollars. Keep in mind that paying the ransom is always a risk to lose your money for nothing. Many extortionists tend to fool their victims and not send any decryption instruments even after receiving the requested money. Unfortunately, there are no third-party decryptors that can guarantee 100% decryption of BlackByte files.

How to remove Ranion Ransomware and decrypt .ransom or .r44s files

0
Ranion is a malware group that develops and spreads ransomware infections. Its recent version is called R44s, which encrypts data using strong cryptographic algorithms and then demands money for its redemption. Victims can spot their files have been encrypted by visual means. First versions of Ranion Ransomware discovered in Novemver, 2017 used .ransom extension. Now the virus assigns the plain .r44s extension to all compromised pieces. Here is a quick example of how files will look after successful encryption - 1.pdf.r44s, 1.jpg.r44s, 1.xls.r44s, and so forth depending on the original file name. Right after this encryption process ends, R44s creates an HTML file named README_TO_DECRYPT_FILES.html.

How to remove Artemis Ransomware and decrypt .artemis, .ultimate or .999 files

0
Discovered by a malware researcher named S!Ri, Artemis belongs to the PewPew ransomware family. Frauds behind this family have spread a number of high-risk infections that run data encryption. Artemis is the most recent variant of file-encryptor that cuts access to most stored data using multi-layer cryptographic algorithms. These algorithms make data thoroughly encrypted, which disables users from opening them. Besides that, encrypted files locked off by Artemis get changed in visual means as well. For instance, a file like 1.pdf will change to something like 1.pdf.id-victim's_ID.[khalate@tutanota.com].artemis and reset its original icon. This string consists of the victims' ID, khalate@tutanota.com email address, and .artemis extension at the end. Then, as soon as encryption gets to a close, Artemis prompts the info-decrypt.hta to appear across the entire screen. Recent versions of the malware use ReadMe-[victim's_ID].txt ransom note name and use .ultimate and .999 extensions (1.pdf.id[victim's_ID].[UltimateHelp@techmail.info].ultimate and 1.pdf.id[victim's_ID].[restoredisscus@gmail.com].999).

Bad Image is a popular file-related issue that pops whilst trying to open an app in Windows 10. It states some file is either not designed to run on Windows 10 or contains some error. Reinstalling a problematic program or contacting software vendors is the only solution offered by the error message.

In most cases, Bad Image errors indicate there is a corrupted or incorrect version of the DLL file specified in the text of the error. This can happen as a result of some crashes, misplaced or non-existent components, damaged updates, and various other similar causes. It is also possible to happen after users downloaded some DLL files from third-party resources to fix other errors. The name of the DLL file written in the Bad Image error message can be quite helpful to pinpoint more accurate reasons for the problem. Normally, people encounter 0xc000012f or 0xc0000020 errors due to issues with Microsoft Visual C++ Redistributable software. If you see your DLL file start with msvcr, msvcp, or other names like ucrtbase.dll, then it is likely to have something wrong with the above-mentioned Visual C++. In all other cases, it is better to google your DLL and get a detailed summary of its emergence. Below, we will show you the most popular and effective solutions that help people get rid of Bad Image errors in most cases.
