How to remove LOL! Ransomware and decrypt .LOL! files

0
Being a new variant of PGPCoder Ransomware, LOL! is also designed to encrypt system-stored data with the help of asymmetric RSA and AES algorithms. Such algorithms are oftentimes strong making manual decryption next to impossible, however, this is yet to be discussed in detail further below. During encryption, the virus also appends its .LOL! extension to each file affected. For an instance, if it was 1.pdf attacked by the encryptor, it would change to 1.pdf.LOL! and become no longer usable. As soon as all targeted files end up access-restricted, the virus drops the get data.txt file to each folder containing encrypted data (including desktop). This file is meant to explain what happened and most importantly instruct victims through the recovery process.

How to remove IceFire Ransomware and decrypt .iFire files

0
IceFire is the name of a computer infection classified as ransomware. Cybercriminals behind it target data encryption of business users and then extort money (in Monero cryptocurrency) for file decryption. While analyzing technical reports of the virus, we saw it using a combination of cryptographic AES + RSA algorithms to encipher important pieces of data. Just like other infections of such, IceFire Ransomware uses its own extension - .iFire to highlight the restricted data. To illustrate, a file previously titled 1.pdf will change to 1.pdf.iFire and become no longer accessible. Following successful encryption, cybercriminals lay out instructions on what recovery steps should be taken within the iFire-readme.txt note.

How to fix RunDLL error in Windows 10

0
On the initial basis, RunDLL (also RunDLL32.exe) is an integral file of Dynamic Link Library modules that function in correlation with the Windows Registry. The proper operation of all DLL files is meant to ensure faster response speed and memory management while using various apps and Windows processes. If one of such files has been deleted, is missing, or Windows is simply unable to verify its location, the system will prompt a box alert with a relevant message about the error that happened. DLL files stated in error messages can vary vastly, depending on which one of them failed to undergo successful verification by Windows. We have already had multiple guides dedicated to some popular RunDLL errors with files like MSVCP110.dll, D3D12.dll, VCRUNTIME140.dll, CONCRT140.dll, MSVCR110.dll, and API-MS-WIN-CRT-RUNTIME-l1-1-0.dll as well. As a rule, users who receive RunDLL errors can encounter messages with slightly different content and also a specified directory where the file could not be found.

How to remove Venus Ransomware and decrypt .venus files

0
Venus is a ransomware-type virus that was recently discovered by a malware researcher called S!Ri. Its main function is file encryption and also the extortion of money for decryption from victims. While enciphering data with cryptographic algorithms, all the affected files get changed with the .venus extension. To illustrate, if 1.pdf ends up affected by the infection, it will become 1.pdf.venus also and reset its original icon. After this, victims get to familiarize themselves with decryption instructions inside of the README.txt note. Desktop wallpapers get replaced as well.

How to remove WildFire Locker Ransomware and decrypt .wflx files

0
WildFire Locker is a malicious program categorized as ransomware. It operates by restricting access to data (with AES-256 CBC encryption algorithms) and then demanding money from victims. During the data encryption process, all targeted files acquire this long and written format #WildFire_Locker#[original file name]##.[original extension].wflx. Cybercriminals do so to highlight encryption and make victims spot it. For instance, a file previously named documents.pdf will therefore become something like #WildFire_Locker#documents##.pdf.wflx and reset its original icon as well. Following this, the virus creates three files with .txt, .html, and .bmp extensions providing relevant information about the decryption procedure. Most detailed instructions are given inside the HOW_TO_UNLOCK_FILES_README_(victim's unique ID).txt text note.

How to fix “Unable to verify update” error on iPhone

0
Unable to verify update. iOS [version] failed verification because you are no longer connected to the internet. is exactly the error some users may receive while trying to install the latest update on their device - most often ranging from iOS 14 to 16. This happens when iPhone cannot establish the proper server connection to retrieve information for update verification. Usually, the most common reason why it occurs is because of unstable or absent internet connection. Sometimes the reason can also be insufficient storage space that has to be freed to let the update install. In case retrying the update does not resolve the issue and continues running into the same message, you can turn down to our guidelines below and fix the problem together with us!

How to fix iPhone (iTunes) error 11

0
Most commonly, victims of this error have had their iPhones operating on iOS 12, 13, 14, or 15. It is also quite similar to other iPhone issues (53, 14, 10, 2015, 1110, 3194, etc.) we have discussed in previous troubleshooting articles on our website. In general, there is no single reason related to the appearance of such errors. The causes may vary broadly in each individual case - badly connected USB cable, outdated software, system glitch, insufficient memory, compatibility issues, and other possible reasons as well. Below, we have gathered a list of solutions that are most likely to resolve the issue and let you update your device eventually. Follow along and try each step we offer until the issue gets resolved.

How to remove PLAY Ransomware and decrypt .PLAY files

0
PLAY is a ransomware-type virus that runs encryption of important data and extorts money from victims. While rendering files inaccessible, it assigns the .PLAY extension and also creates a text note called ReadMe.txt. For instance, a file previously titled 1.pdf will change to 1.pdf.PLAY and reset it's icon after encryption. Since then, victims lose control over their data and have to read instructions on its recovery in the created text note. It is common for ransomware infections to be distributed via phishing techniques. A virus may be disguised as some legitimate-looking file (e.g., Word, Excel, PDF, EXE, JavaScript, RAR, ZIP, etc.) and be sent inside of an e-mail spam letter. Such a letter may present information explaining the “importance” of opening attached files or links.
