N01.biz is one of thousands of spam websites, that are used by third-party advertisers to deliver unwanted and annoying ads on user's desktops via browser push notifications. It targets all popular browsers, like Google Chrome, Mozilla Firefox, Safari, Edge on all major types of devices and operating systems (Windows, Mac, Android, iOS). N01.biz tricks users into allowing push-notifications, which grants it permission to show ads and pop-ups in form of notifications on the desktop or in the notification field on smartphones. These ads may contain malicious links or lead to third-party commercial sites, promote low-quality goods and services. Infection by N01.biz can be presented just by browser setting modification or by installed adware in form of browser add-on or app. In most cases, unwanted setting can be cleaned manually, but we recommend using an antimalware tool to make sure all traces and instances of malware were removed. In this article we explain all necessary steps to get rid of N01.biz.

Kiop Ransomware is another representative of STOP/Djvu virus, that has been tormenting users since 2017. This particular version was released in the beginning of April 2023 and adds .kiop extension to all encrypted files, as can be seen from its name. Other than that, it's the same file-encypting and ransom-demanding virus as hundreds of its predecessors. Ransomware of this type uses the same cryptography, that is, unfortunately, still undecryptable. Kiop Ransomware, like other variants of STOP/Djvu Ransomware, typically uses a combination of symmetric and asymmetric encryption algorithms to encrypt the victim's files. Specifically, the ransomware uses AES-256 encryption to encrypt the victim's files symmetrically, and then uses RSA-2048 encryption to encrypt the AES encryption key asymmetrically. This means that the attacker holds the private RSA key needed to decrypt the AES encryption key, and therefore can decrypt the victim's files after receiving payment.The only things that change during last years are extension and contact e-mail addresses. The name of the ransom note remains unchanged (_readme.txt) and you can check the content in the text box below.

Skylock is a new ransomware variant originating from the MedusaLocker family. Upon successful infiltration, the virus encrypts access to files (based on AES and RSA cryptography) and assigns the .skylock extension to them. For instance, a file like 1.pdf will change to 1.pdf upon successful encryption. To reverse the damage and return the blocked data, cybercriminals present decryption instructions inside the How_to_back_files.html file. In general, victims are told they need to purchase special decryption software from cybercriminals behind the infection. To do so, they have to establish contact with the extortionists using one of the communication channels (either via the link in the TOR browser or provided e-mail addresses). It is also said victims can send 2–3 files that do not contain any important information and get them back decrypted for free. This is to prove that threat actors are actually capable of decrypting the files. Should victims refuse to get in touch with the extortionists and pay for decryption, their data will be leaked to public resources, which may incur reputational damage to the users' company or personal identity. Unfortunately, despite the fact that decryption can be unaffordable or needless for some users, cybercriminals are usually the only figures able to decrypt access to data.

Global PC Cleaner Pro is a system optimization utility allowing its users to detect and remove computer issues, delete unwanted items, install and uninstall apps, boost RAM performance, as well as use the in-built VPN feature. However, please be aware that Global PC Cleaner Pro is classified by many antivirus engines as unwanted and even malicious. One of the reasons is that such apps tend to provide fake issue/threat results to convince inexperienced users that their system is full of junk or problems that need to be taken care of. After running the scan of the system, Global PC Cleaner Pro guides users to contact the provided support number for assistance in removing the issues. Note that calling numbers promoted by this or similar utilities will likely lead to scammers. Multiple instances show that such people ask users to give remote access to their PCs so that they could perform the necessary "cleaning measures". In fact, providing remote access to unknown persons is extremely risky as they can inject malware into your system (e.g., ransomware, crypto-miners, etc.) or trick you into paying money for their services. It is likely that your system does not contain the detected problems. Thus, do not trust suspicious apps like Global PC Cleaner Pro and delete them from your system using our article below.

Waicaiwhosha.com may use browser push notifications to display unwanted pop-up ads to users. When a user visits the website, they may be prompted with a notification asking for permission to display notifications. If the user grants permission, the website can send push notifications to the user's browser even when they are not actively browsing the site. These notifications can appear as pop-up ads, banners, or alerts, and may contain links to other potentially harmful websites. The notifications can also be used to collect personal information from the user, such as their browsing history or location data. It is important to note that users can control which websites are allowed to send push notifications in their browser settings. If you have inadvertently granted permission to Waicaiwhosha.com or any other suspicious website, you can revoke the permission in your browser settings to prevent further notifications from being displayed. Waicaiwhosha.com can potentially affect various operating systems including Windows and Mac, as well as mobile devices such as Android and iPhone. Websites infects various web browsers including Google Chrome, Mozilla Firefox, Microsoft Edge, Internet Explorer, Safari, and others.

If your files became unavailable, unreadable, and got .kiwm extensions it means your computer is infected with Kiwm Ransomware (variation of STOP Ransomware or as it is, sometimes, called DjVu Ransomware). It is a malicious program that belongs to the group of ransomware viruses. This particular version was released in the beginning of April 2023. This virus can infect almost all modern versions of the operating systems of the Windows family, including Windows 7, Windows 8, Windows 10 and the latest Windows 11. The malware uses a hybrid encryption mode and a long RSA key, which virtually eliminates the possibility of selecting a key for self-decrypting files. Like other similar viruses, the goal of Kiwm Ransomware is to force users to buy the program and key needed to decrypt files that have been encrypted. The version, that is under research today, is almost identical to the previous ones, except for new e-mails used for contacting malefactors and new extensions added.

When trying to launch certain games or programs, users may encounter a message stating that the system is unable to find the vulkan-1.dll file, or that it is missing from the computer. Vulkan-1.dll is part of the Vulkan Runtime Libraries, which can be used in various games for Windows 11, 10, or 7. Usually, games containing this file are based on engines from Valve. Thus, it is more common to see this error while launching games from Steam. Below, we will show you a couple of ways to potentially restore the missing vulkan-1.dll file and remove the error respectively. As a rule, the Vulkan Runtime Libraries package is supplied and installed with video card drivers by default. However, if the drivers were automatically installed by the system, it is recommended that users manually download-install the latest drivers from the official websites of Nvidia GeForce, AMD Radeon, and Intel. After doing so, the missing file should be restored to the correct locations to start the problematic game/program.
