Poteston is classified as a ransomware infection that runs encryption of databases, photos, documents, and other valuable data. The whole encryption process can be easily spotted by users looking at new extensions assigned to files. This virus involves the .poteston extension to rename the stored data. To illustrate, a file named 1.pdf will change its look to 1.pdf.poteston as a result of encryption. As soon as these changes are seen, victims will no longer be able to access the data. As soon as these changes are seen, victims will no longer be able to access the data. To restore it, users are given instructions inside of the readme.txt note. Within the note, victims are greeted with bad news - all data we mentioned above has been encrypted. To redeem it back, victims are instructed to contact cyber criminals using their e-mail address (recovery_Potes@firemail.de). After establishing contact with them, you will be supposedly given the necessary details to perform a money transfer. Before doing so, you are also offered to send one of the blocked files for free decryption. This is a trick used by many extortionists to elevate the trust of victims. In addition to that, Poteston developers also inform against renaming encrypted data as you can potentially damage its configuration.

MANSORY is a ransomware infection that runs vigorous encryption on personal and business data. This process involves cryptographic algorithms along with the appendance of new extensions. MANSORY uses the .MANSORY extension to each file piece that has been restricted. For instance, a file like 1.pdf will be changed to 1.pdf.mansory. After experiencing such changes, the blocked files will be no longer accessible. In order to regain access to them, victims have to pay a certain ransom in money. More information on that is presented inside a text note called MANSORY-MESSAGE.txt, which is created after the encryption is done. The first thing cybercriminals say is that gigabytes of valuable data have been downloaded to a secure location. Extortionists use it as collateral for intimidating users with the publication of data in case they refuse to pay money. Victims have a right to know how much data has been uploaded after contacting the cybercriminals via e-mail (selawilsen2021@tutanota.com; dennisdqalih35@tutanota.com; josephpehrhart@protonmail.com). Therefore, they can analyze the value of data that leaked into the hands of extortionists. As we already mentioned, not contacting cybercriminals will result in the gradual publication of data that has been hijacked from your network. To avoid it, victims are required to purchase the decryption software stored by cyber criminals themselves. This will also allow you to unlock all of the blocked data. Besides that, developers of MANSORY Ransomware offer to try free decryption by sending 2 random files from other computers to their e-mail.

0x80240034 is an error code that prevents users from installing an update known as Windows 10 Insider Preview 16215.1000. Most people reported this update to get stuck at 1% and therefore crash receiving the corresponding error. There are hundreds of similar errors, which have the same source of reasons. Normally, they tend to occur due to damaged PC configuration caused by missing or corrupted files, software incompatibility, and many other reasons that require a separate solution. Below, we have provided a full guide dedicated to troubleshooting the 0x80240034 error. Read all instructions carefully and do not skip over the steps suggested by our experts.

Also known as Superfetch, SysMain is a native Windows service meant to optimize system performance. However, some users tend to stumble into serious problems whilst having SysMain turned on. The service can eat a lot of resources, increasing disk and CPU usage significantly. This, therefore, results in freezes, slowdowns, and many other things deteriorating the system. If you open the Task Manager, you will see the SysMain service on top of the list demanding a high number of resources. It is quite strange that something meant to improve your system does completely the opposite, but this is the reality of Windows OS. Sometimes SysMain can go awry leading to terminates and overheating issues. If not resolved in time, your hardware may suffer serious damage and end up dying eventually. Luckily, there is a solution to this. Simply follow the instructions listed below.

FindNoteFile is the name of a ransomware infection that started its hunt for business users in June 2021. Just like other malware of this type, developers use AES+RSA algorithms to encrypt victims' data. FindNoteFile has been found distributed in 3 different versions. The only big difference between them is the name of the extension assigned to files after encryption (.findnotefile, .findthenotefile, or .reddot). For example, a file initially called 1.pdf will change its appearance to 1.pdf.findnotefile, 1.pdf.findthenotefile, or 1.pdf.reddot depending on which version attacked your system. Then, as soon as encryption is over, the virus creates a text note called HOW_TO_RECOVER_MY_FILES.txt, which contains ransom instructions. The text written inside is full of mistakes, however, it is still easy to understand what cybercriminals want from their victims.

Kernel-Power is an unexpected error displayed in Windows Event Viewer as critical. Windows describes this error as a result of your system being rebooted without cleanly shutting down first. It also states that this error may be associated with system crashes, loss of power, and other unexpected problems erupting for unexplained reasons. In log details of the error, users can see a number of metrics helping to pinpoint the problem. The Kernel-Power issue has Event ID 41, which means there is a problem of incorrectly shutting down your system. It usually pops when Windows cannot finish the session correctly and forced to restart after the last shutdown. As a rule, such problems emerge when there is an improper power supply. This can be related to hard disks, memory, and other additional devices that have destabilized power supply. In order to fix it, there is a couple of basic solutions that helped a lot of people resolve the problem. Follow our detailed instructions to do them below.

0x800f0984 (PSFX_E_MATCHING_BINARY_MISSING) is an update-related error that appears on Windows 10. Such issues pop up quite often when trying to install incoming updates or patches. As statistics show, such problems are faced due to corrupted files or settings, incompatible software, and other reasons that conflict with the update center. Below, we will walk through all of the steps that are more likely to resolve the 0x800f0984 issue.

EpsilonRed is another ransomware-type virus that targets personal data on infected systems. Once it finds the range of data it needs (normally it is databases, statistics, documents, etc.), the virus starts running data encryption with AES+RSA algorithms. The entire encryption process is hard to spot out immediately as victims become aware of the infection only after all files have changed their names. To illustrate that, let's take a look at the file named 1.pdf, which therefore changed its appearance to 1.pdf.epsilonred. Such a change means it is no longer permitted to access the file. Besides pursuing sensitive data, it is also known that EpsilonRed alters the extension of executable and DLL files, which may disable them from running correctly. The virus also installs a couple of files that block off protectionary layers, clean Event logs, and affect other Windows features once the infection has snuck into the system. At the end of encryption, EpsilonRed provides ransom instructions presented inside of a note. The name of the file may vary individually, but most users reported about HOW_TO_RECOVER.EpsilonRed.txt and ransom_note.txt text notes getting created after encryption.
