Odestech.com is a deceptive website existing in various versions to bait users into allowing push-notification requests. These versions vary in methods it uses to trick future victims. Odestech.com can ask you to allow push-notification under the pretext of Watching a video, Confirming that you are not a robot, Verifying Captcha, Downloading a file, and other kinds of action. These requests are fake and meant only to make users permit the aforementioned. After clicking on the Allow button, the website will be able to generate ads and send them right to the desktop. Such ads are heavily doubted and should never be trusted. It is likely they can promote redirects to suspicious or dangerous websites. Usually, many people visit pages like Odestech.com by accident, whilst clicking on dubious ads or buttons that trigger a chain of various websites to open before you get routed to the desired page. If you see Odestech.com open in your browser consistently, this means you have adware installed on your PC. To get rid of it and prevent Odestech.com from showing its ads, we encourage you to follow our tutorial below.

Ioqa Ransomware (a.k.a. STOP Ransomware or Djvu Ransomware) is an extremely dangerous virus that encrypts files using AES-256 encryption algorithm and adds .ioqa extensions to affected files. The infection mostly involves important and valuable files, like photos, documents, databases, e-mails, videos, etc. Ioqa Ransomware does not touch system files to allow Windows to operate, so users will be able to pay the ransom. If the malware server is unavailable (computer is not connected to the Internet, remote hackers' server does not work), then the encryption tool uses the key and identifier that is hard-coded in it and performs offline encryption. In this case, it will be possible to decrypt the files without paying the ransom. Ioqa Ransomware creates _readme.txt file, that contains ransom message and contact details, on the desktop and in the folders with encrypted files. Developers can be contacted via e-mail: support@freshmail.top and datarestorehelp@airmail.cc.

Mikel Ransomware is a malicious infection designed to encrypt personal data and extort money for its decryption. It is also identified as a new variant of another file-encryptor named Proxima. During encryption, Mikel Ransomware assigns the .mikel extension to highlight the change. For instance, a file like 1.pdf will change to 1.pdf.mikel and reset its original icon. Please note that deleting the assigned extension from the encrypted file will not return access to it. Encryption makes data permanently locked and requires decryption keys to unlock it. After the encryption is complete, the virus creates the Mikel_Help.txt text note with instructions regarding decryption.

Users whose website is constantly redirected to the s3.amazonaws.com domain without permission are likely affected by unwanted extension or program that lurks in the system. Both Mac and Windows users have reported encountering this issue. S3 Amazonaws.com is a legitimate content delivery network (CDN) provided by Amazon that can be used by website publishers to generate revenue on their websites. However, there are harmful programs that can send users to S3.amazonaws.com without the publisher's authorization in order to retrieve illegal profits. As a rule, unwanted software that abuses this scheme may redirect users to ads promoting unwanted software, fake updates, online games, casinos, adult pages, surveys, and other kinds of dubious resources that should be avoided. If you end up on S3.amazonaws.com unwillingly and without your consent, it is advised to close this page and scan your system for potential adware infection. Read our guide below to learn how to do it.

MoUSO Core Worker Process (MoUsoCoreWorker.exe) is a Windows service responsible for managing the sequence on which updates are downloaded and installed onto the operating system. In other words, it helps Windows determine which update will be installed in the first order. As a rule, this service gets itself running only when scanning for updates. However, in certain cases, users may see it continue its operation for an extended period of time for no obvious reason. As a result, this may lead to higher consumption of CPU, RAM, or/and Disk usage, making your computer laggier and slower to use even for simple tasks. The most popular causes for the unusual behavior of the MoUSO Core Worker Process are that it or other update-related services could become temporarily bugged, there are pending updates, or, in rarer cases, your system is infected with malware that mimics the MoUSO Core Worker (MoUsoCoreWorker.exe) process. Follow our guide below and try all the suggested methods to potentially resolve the high memory/CPU/disk usage. Note that instructions in our guide were made on the basis of Windows 11, keep in mind that they may vary slightly on Windows 10.

STOP Ransomware is a sophisticated encryption virus, that uses the Salsa20 algorithm to encode sensitive personal data, such as photos, videos, and documents. The latest version (Iowd Ransomware), appeared in the middle of February 2023, adds .iowd extension to files and makes them unreadable. To date, the family includes about more than 600 representatives, and the total number of affected users is approaching a million. Most of the attacks are in Europe and South America, India, and Southeast Asia. The threat also affected the United States, Australia, and South Africa. Although the Iowd virus is less known than GandCrab, Dharma, and other ransomware trojans, it is this year that accounts for more than half of the detected attacks. Moreover, the next rating participant, the aforementioned Dharma, lags behind him by this indicator by more than four times. A significant role in the prevalence of STOP Ransomware is played by its diversity: in the most active periods, experts found three or four new versions daily, each of which hit several thousand victims.

Crackonosh is the name of a trojan stealthily distributed inside cracked software installers. Upon successful installation, its purpose is to inject the XMRIG miner and start mining Monero cryptocurrency for the threat actors. As of now, statistics show that this miner has helped cybercriminals mine the amount of Monero worth roughly two million dollars. A couple of words on how the trojan does its malicious job: After the installer of cracked software is launched, it places an installer and script onto the targeted system, which then changes the Windows Registry settings to turn off hibernation mode and activate Crackonosh in Safe Mode at the next system start-up. This way, the trojan deactivates Windows Update and Windows Defender and is even able to uninstall third-party antivirus programs (e.g., Avast, Bitdefender, Kaspersky, McAfee, and Norton) in order to reduce the chance of getting detected and blocked. To conceal its presence, it erases system log files, serviceinstaller.msi files, and maintenance.vbs files. As a result, some infected systems may display error messages indicating issues with the aforementioned files. In addition, Crackonosh may also halt Windows Update services and substitute the Windows Security icon with a fake green system tray icon. The main symptoms that should attract your attention and lead you to suspect something is wrong with your system are usually slower and laggy PC performance, increased CPU/GPU/RAM usage, overheating, unexpected crashes, and other related issues. Thus, if any of these symptoms are present, make sure to read our guide below and eliminate the potential crypto-mining trojan from your computer.

Users may receive fake e-mail letters asking to verify their MetaMask wallet as part of completing the KYC verification process. MetaMask is one of the most popular digital wallets allowing people to store and transfer crypto assets, such as Ethereum. Such messages sent under the MetaMask name belong to phishing e-mail spam campaigns, which are designed to trick users into exposing their wallet credentials. Specifically, cybercriminals urge users to click on attached buttons or links leading to a phishing website. This website, therefore, asks users to provide their secret wallet keyword phrase to ostensibly pass the aforementioned verification. Unfortunately, doing so will simply enable cybercriminals to hack the wallet and steal money from it. Note that e-mail scam messages tend to use various psychological tricks to destabilize users' thinking and force them to make rushed decisions - for instance, the fake MetaMask letter stated the account will be restricted unless users complete verification within the specified date. While some details and even the appearance of e-mail scam messages may be sent by various threat actors and therefore vary from user to user, their purpose often remains the same - to scam naive users or download malware into the system. Thus, it is important to beware of such messages and not trust what they say. Always double-check the claimed information on the official website of the service involved, even if the message seems totally legitimate. In addition, we encourage you to read our guide and learn about other dangers of e-mail spam messages and aversion techniques against them.
