How to remove U2K Ransomware and decrypt .U2K files

0
U2K is a ransomware virus designed to render files inaccessible and extort a recovery payment from victims. During encryption, it assigns the .U2K extension and resets icons of all affected files. To illustrate, a file initially titled 1.pdf will change to 1.pdf.U2K and lose its original icon as well. After getting things done with encryption, the virus triggers the creation of the ReadMe.txt text note. This note features instructions on what victims should do in order to return the blocked data. As stated inside the file, the only doable way of decrypting all data is to purchase a unique decryptor. To retrieve it, victims are guided to download Tor Browser, navigate to the attached website link, and open a support ticket with cybercriminals. After starting negotiations, extortionists will likely announce the price and instruct victims on further details for payment. Unfortunately, as experience shows, much damage (primarily encrypted files) is hard to recover without the help of cybercriminals.

How to fix OneDrive “The tag present in the reparse point buffer is invalid”...

0
The tag present in the reparse point buffer is invalid or error 0x80071129 is a kind of message a user may receive while trying to use Microsoft OneDrive. This error often occurs when the On-Demand OneDrive feature is on. While this functionality unlocks an easier path to managing files, it sometimes leads to facing problems in the form of such errors. As a rule, the most likely reason for this is some disk corruption that prevents OneDrive from backing up junction files. Alternatively, it can otherwise be a OneDrive fault related to cache or even an internal Windows bug that can be solved only through updating. Whatever it is, we recommend you try each of the three methods presented below to resolve the OneDrive "The tag present in the reparse point buffer is invalid" error. This solution will most likely resolve the issue. We should though warn you that despite the effectiveness of this method, it might not be able to solve the issue forever. Many users reported that have to enter this command multiple times to get a temporary room for OneDrive usage.

How to remove Lilith Ransomware and decrypt .lilith files

0
Lilith is a ransomware infection that encrypts system-stored data and demands payment for file decryption. While rendering files inaccessible, the virus also appends the new .lilith extension to each infected sample. For instance, a file named 1.pdf will change to 1.pdf.lilith and reset its original icon as well. After this, cybercriminals lay out instructions on how to acquire decryption in a text note called Restore_Your_Files.txt. It is said that victims have three full days to contact developers. This should be done using the Tox messenger in Tor Browser. Should victims get late with meeting these demands, cybercriminals threaten to start leaking the collected data, supposedly to dark web resources. Although the price for decryption is calculated on an individual basis depending on how much valuable data has been encrypted, it still might be quite high considering ransomware's tendency to target business organizations.

How to remove JENNY Ransomware and decrypt .JENNY files

0
JENNY is the name of a new file-locker discovered by MalwareHunterTeam. Malware of such is normally designed to restrict access to data and demand victims to pay a ransom in crypto. After successfully infiltrating the system, the virus encrypts important pieces of data and also assigns the .JENNY extension. This means a file like 1.pdf will change to 1.pdf.JENNY and reset its original icon to blank. After this part is done, the ransomware replaces desktop wallpapers and features a pop-up window right on the screen. Unlike other ransomware infections, JENNY developers do not provide any decryption instructions. Victims are left confused with absolutely no contact information to use for reaching the cybercriminals. The reason for that could be because this ransomware is still under development and is likely being tested. This means decryption with the help of developers is impossible and that a complete version of JENNY may be released some day in the future.

How to remove BlueSky Ransomware and decrypt .bluesky files

0
BlueSky Ransomware is a devastating file encryptor. It restricts access to data and requests victims to pay a fee for its return. While running encryption of system-stored data, the virus also assigns the .bluesky extension to each affected sample. For instance, a file named 1.pdf will change to 1.pdf.bluesky and reset its original icon. Since then, files will be no longer accessible. To make victims pay the ransom, cybercriminals layout identical decryption instructions in both # DECRYPT FILES BLUESKY #.html and # DECRYPT FILES BLUESKY #.txt text notes, which are created after encryption. Inside, extortionists say the only case when files can be recovered is if victims purchase a special decryption key and software. They also say that any third-party attempts to decrypt files without the help of cybercriminals may result in permanent damage to data. Victims are thereafter instructed to download Tor Browser and visit the provided web link. After following that, victims will be able to see the price for decryption and additional information such as how to create a wallet and purchase cryptocurrencies as well. The decryption price is set at 0.1 BTC ≈ $2,075 and is said to double in 7 days after the ransomware attack. Cybercriminals also offer to test decryption, as victims can send one blocked file and get it decrypted for free. Ransomware developers tend to do this in order to validate their trustworthiness and boost victims' confidence in paying the ransom.

How to remove FARGO Ransomware and decrypt .FARGO files

0
FARGO is a typical file-encryptor that restricts access to data and keeps it locked until the ransom is paid. It was also determined to be a new variant of the TargetCompany family. During encryption, the virus highlights affected files by adding a new .FARGO extension. For instance, a file originally titled 1.pdf will change to 1.pdf and reset its icon to blank. After getting successfully done with file encryption, the ransomware creates a text file called FILE RECOVERY.txt that features decryption instructions. Cybercriminals say that the only path towards recovering data is to buy a special decryption tool. For this, victims are instructed to contact extortionists via their email address (mallox@stealthypost.net). It is also stated victims should include their personally-generated ID in the message. To demonstrate that their decryption software actually works, threat actors offer free decryption of some non-valuable files. After sending these files, extortionists promise to assign the price for decryption and give payment instructions. Unfortunately, we have to let you know that manual decryption without the help of ransomware developers is almost impossible.

0
We can't install this printer right now is usually a 740 error that may chase down users while trying to add a new printer to the device list. This is the kind of message users tend to receive when facing this issue: "That didn’t work. We can’t install this printer right now. Try again later, or contact your network administrator for help. Error: #740." The most common reasons for its appearance are usually insufficient administrative privileges, problematic printer drivers, and other technical difficulties such as temporarily malfunctioned printer servers. In this guide, we are going to show you a couple of methods that may potentially resolve the error and let you connect your printer without the same problem occurring. When connecting a printer and therefore trying to add it, Windows does all the job in the background without you seeing many details. In this method, we will try and run the printer installation wizard manually - through the Command Prompt console. This will help initiate installation with administrative privileges and potentially succeed in doing so.
