WHEA_UNCORRECTABLE_ERROR is one of the BSOD (Blue Screen of Death) errors that are commonly seen in Windows 10. The error results in a sudden system crash during regular usage. After that, most users get confused since they have never encountered such a problem before and do not know how to fix it. If not taken seriously, multiple system failures can damage your hardware and lead to data loss. Besides that, the basic reasons for this error are drivers or hardware issues, overlocking, file corruption, and others. If "WHEA_UNCORRECTABLE_ERROR" started appearing on your computer, we will help you get rid of this annoying issue in the article below.

In case you are wondering why your data is blocked and became inaccessible, then N2019cov Ransomware has penetrated your system. Being one of the file-encrypting programs, N2019cov locks unprotected data and tricks users into paying a ransom in Bitcoin. After successful encryption, all files get altered with .P4WN3D extension. For example, the original 1.mp4 will be transformed into 1.mp4.P4WN3D. Thereafter, the program will generate a ransom-demanding message inside of the 1nF0rM@t1On.txt text document that notifies users about data encryption and recovery methods. Extortionists ask you to transfer 100 Euro to the attached wallet and If you do not know how to do so, there is a link to the official website explaining how bitcoin operates. Once the transaction is paid, you have to send a confirmation e-mail to X.cryp.0.R@gmail.com (or other) to retrieve the blocked data.

Receiving any BSOD (Blue Screen of Death) errors can be very frustrating and annoying especially when you do not know how to solve the appeared problem. During regular work or browsing, users may be interrupted with a sudden shutdown resulting in a Blue Screen. DPC_WATCHDOG_VIOLATION is an error code that pops up due to hardware/software incompatibility, damaged files, and driver issues. However, there is no reason to worry since we will help you get rid of this problem in the article below.

Velar is a type of malware classified as ransomware. Ransomware is a category of malicious software that operates by encrypting data and extorting money from users via ransom techniques. During the encryption process, all files are getting configured and obtain new extensions. For example, the non-infected file called 1.mp4 will be renamed to 1.mp4.Velar and reset its default icon. Thereafter, users are presented with a text file displaying the ransom information. The ransom note is called readme.txt. It claims that your system was infected by ransomware that ciphered a large number of files by using a hybrid encryption scheme. In order to restore the blocked data, extortionists ask you to contact them via one of the e-mails and attach your personal ID that is listed in the note. Unfortunately, the only option to access your files is buying a decryption key held by cybercriminals because none of the third-parties software is able to decrypt the infected data. However, it is not recommended to follow the instructions of frauds and paying a ransom because most people get fooled and the problem remains unsolved as a result.

If you are no longer able to access your files, then this is because ransomware infected your system. SD (Unlock11) Ransomware is not an exception since it ciphers users' data with RSA + Salsa20 algorithm and adds brand new .[unlock11@protonmail.com].enc extension to each file. As an example, standard 1.mp4 will be renamed to 1.mp4.[unlock11@protonmail.com].enc after the encryption process is done. It is necessary to point out that .enc extension is more generic and has been exploited by several types of ransomware including MOTD, TrueCrypter, and Cryptohasyou. After successful encryption, the program automatically opens a ransom note ReadMeToDecrypte.txt, which contains the details on how to decrypt your data. Some versions of SD replace desktop wallpaper for displaying the ransom information. In both cases, to unlock the affected files, users should reach out to cybercriminals via unlock11@protonmail.com. You are also allowed to attach 3 files (less than 5MB) so that swindlers could prove they can be trusted. After sending a message, you will be presumably required to pay a specific sum to unlock your data. Furthermore, they will give you recommendations on how to protect yourself from further attacks. Unfortunately, there is no other option at this moment to decrypt files configured by SD Ransomware without paying the ransom and getting the private keys.

BSOD (Blue Screen of Death) errors might be the chief problem that has been targetting most Windows users. This time around, we are facing VIDEO_TDR_FAILURE error that pops up due to the system crash. The problem is displayed on a Blue Screen saying that your PC encountered a problem and soon to be rebooted for automatic repair. "VIDEO_TDR_FAILURE" is typically caused by display driver malfunction. However, sometimes it can be related to other problems like file corruption, disk failures, and malware infiltrations. Unfortunately, it is impossible to eradicate all errors, so you have to keep an ear to the ground for further engagements. In this article, we will provide necessary information on how to get rid of this glitch and get back to normal usage.

Being part of the Dharma family, Dharma-Harma is a ransomware program based on AES-256 + RSA algorithms that are meant to encrypt user's data. After the virus gets settled on the system, it blocks multiple files by putting unbreakable ciphers. Once encrypted, files undergo a couple of significant changes. Firstly, the affected files are altered according to such pattern: original_filename.{random-8-digit-alphanumerical-sequence}.[e-mail-address].harma. Note that cybercriminal's e-mail may vary from person to person. Once the encryption is finished, Dharma-Harma generates a text file or image that contains ransom information. It says that your computer is unprotected and needs to be fixed. To restore the lost files, you have to contact them through the attached e-mail. After that, they will supposedly give further instructions and demand a payment in BTC. Unfortunately, those victims who decided to pay a ransom, often get fooled and do not get any decryption keys.

Ouroboros Ransomware (a.k.a. Zeropadypt Ransomware) is an extremely dangerous virus, that forcibly encrypts and blocks off the access to personal data. By doing so, Ransomware developers prompt users to pay a ransom (around 1000$) for getting a unique decrypting key. When infiltrating the device, it immediately starts rushing through files like images, videos, music, text documents and other valuable data that can be stored on your computer and encrypts it by using the AES-256 encryption algorithm. After that, ransomware assigns a unique .odveta extension to each file, therefore, making it impossible to open. For example, if sample.mp4 gets encrypted it will change the file name to sample.mp4.odveta. There are many other versions and variation of Ouroboros Ransomware, that change file extensions to .bitdefender, .harma, .rx99, .Lazarus, .Lazarus+, .James, .lol, .hiddenhelp, .angus, .limbo, or .KRONOS. Some of the recent extensions like .bitdefender, were created as mockery, because BitDefender released decryption tool, that, unfortunately, cannot decode latest Ouroboros Ransomware species.
