PUA:Win32/Presenoker is a detection name used by Microsoft Defender Antivirus and other security tools to identify Potentially Unwanted Applications (PUAs). These applications often appear legitimate and useful but may operate in ways that are undesirable or harmful to the user. They can include adware, browser hijackers, and other software with unclear objectives. Manual removal involves navigating to specific directories on your computer and deleting the files associated with Presenoker. This can be done by accessing the File Explorer and removing the contents of the DetectionHistory folder and CacheManager folder within the Windows Defender directory. Since Presenoker often changes browser settings, resetting the browser to its default settings can help remove the unwanted changes. This can be done through the browser's settings menu. Running a full system scan with reputable antivirus software like Malwarebytes, Spyhunter, Norton can help detect and remove Presenoker and other related malware. These tools can automatically identify and quarantine malicious programs.

Coyote is a multi-stage banking Trojan that leverages the Squirrel installer for distribution, a method not commonly associated with malware delivery.

Removing Vidar from an infected system requires a multi-step approach. First, it's crucial to use a reputable antivirus or anti-malware tool to scan for and remove any traces of the Trojan. Manual removal can be complex and involves deleting malicious registry keys, files, and unregistering DLLs associated with Vidar. However, manual removal is not recommended for inexperienced users due to the risk of damaging the operating system.

Secoh-qad.exe virus is a malicious file associated with KMSPico, a tool used to illegally activate Windows Operating Systems and Microsoft Office suites. This tool bypasses software activation free of charge, and when installed with active anti-virus software, the security software will detect the secoh-qad.exe file as a threat. The virus is designed to infect a computer or network system, often damaging, disrupting, or stealing data. It can spread from computer to computer and can even affect entire networks. Computer viruses can be spread through downloads, removable storage media such as USB drives, and even email attachments.

SPICA Backdoor is a type of malware that has been linked to a Russian threat actor known as COLDRIVER. It is a custom malware written in the Rust programming language and is designed to infiltrate computer systems stealthily. Once inside a system, it establishes a connection to a Command and Control (C&C) server and waits for commands from its operators. These commands can include executing shell commands, managing files, and stealing information. The malware was first observed by Google's Threat Analysis Group (TAG) in September 2023, but evidence suggests that it has been in use since at least November 2022. SPICA is notable for its use of websockets for communication with its C&C server and its ability to execute a variety of commands on infected devices. To remove SPICA from an infected computer, it is recommended to use legitimate antivirus or anti-malware software that can detect and eliminate the threat. Users should perform a full system scan to ensure that all components of the malware are identified and removed.
