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.pdfwill change its appearance to
1.pdf.reddotdepending 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.
SLAM is a ransomware-type virus that encrypts personal data to earn money on desperate users. In other words, it restricts access to data and keeps it under lock until victims pay a certain ransom fee. To make users spot the encryption, developers rename the compromised data using the .slam extension. To illustrate, a file like
1.pdfwill be retitled to
1.pdf.slamand reset its original icon (in some cases). Then, after this part of encryption is done, SLAM opens a window stating information about the virus. Red text on the black background says that all files have been encrypted. In order to get them back, victims are asked to contact cybercriminals using one of the e-mails attached to the note. Thereafter, you will be given the necessary instructions to perform a transfer of ransom in money. In addition to that, users are warned that shutting down the PC, or using Windows applications (e.g. regedit, task manager, command prompt, etc.) is forbidden. Otherwise, your PC will be locked and denied from getting boot up until the virus is present. The same will happen unless you contact extortionists within 12 hours. At this point of the investigation, cyber experts have not been yet able to find a tool that could provide data decryption for free, without involving the cybercriminals. Paying the ransom is also a risk as there is no guarantee that you will receive your files back. The only best way in this situation is deleting SLAM Ransomware and recovering your data via backup copies. If you do not have them created and stored in a separate location prior to the infection, then it is almost unreal to decrypt your files.
Qscx Ransomware, being a part of STOP Ransomware is a critical virus, endangering user's personal files. It belongs to the family of file-encrypting malware, that uses the AES (Salsa20) algorithm and unbreakable key. This virus is, sometimes, called DJVU Ransomware, after the word used as an extension in the first versions (.djvu). The variant of the threat, that we describe today, modifies files with .qscx extension. Files are encrypted with a secure key and there are quite small chances to decrypt them completely. However, certain manual methods and automatic tools, described in this article can assist you to successfully decrypt some data. The price of decryption of files encoded by STOP Ransomware is $490 (or $980, if not paid within 72 hours). But as statistic shows, it is pointless to pay any money, as malefactors almost every time ignore the victims. STOP Ransomware purposefully encrypts important personal information: videos, photos, documents, local e-mails, archives. It detects and attacks a type of data, that can be so critical to users to pay such an amount of money for. If there are any realistic chances to recover files with the .qscx extension, you can do it with a special utility called Emsisoft Decryptor for STOP Djvu, which can be downloaded below.
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.
