The Kotalq App is a Potentially Unwanted Application (PUA) that has been identified as a dropper for the Legion Loader malware. This particular application was discovered as part of a malicious installer on a rogue webpage. Along with its primary payload, Kotalq App also installs a fake browser extension named “Save to Google Drive”, which further compromises the user’s system. In this article, we will delve into the details of Kotalq App, its potential impacts on a system, and provide a comprehensive guide on how to remove it with SpyHunter, along with preventive measures to avoid future infections.
Threat Overview
Kotalq App is classified as a Potentially Unwanted Program (PUP), which are applications that may not be outright malicious but exhibit undesirable behaviors. These behaviors often include unsolicited pop-up ads, system slowdowns, or bundling with other harmful software. The primary risk posed by Kotalq App, however, is its role as a dropper for Legion Loader, a notorious malware capable of delivering a wide range of other threats to an infected system.
Legion Loader’s capabilities include:
- Downloading and installing additional malware, such as trojans, ransomware, cryptominers, and malicious browser extensions.
- Infecting systems with programs designed to steal personal data, spy on users, and disrupt system performance.
One of the most concerning aspects of Kotalq App’s payload is the fake “Save to Google Drive” extension, which masquerades as a legitimate browser extension. This extension has the potential to gather sensitive information, modify browser behavior, and cause unwanted pop-ups or redirects, further compromising user security and privacy.

Detailed Breakdown of Kotalq App and Its Impact
Legion Loader: The Core Malware
Legion Loader, the primary payload dropped by Kotalq App, is a dangerous tool used by cybercriminals to install additional malware on compromised systems. Once it infects a device, Legion Loader can:
- Deploy trojans that can steal sensitive data, spy on the user, or even control the system remotely.
- Install ransomware, which encrypts files and demands payment for their decryption.
- Introduce cryptocurrency miners, which hijack system resources to generate cryptocurrency, resulting in a significant slowdown of system performance.
- Install malicious browser extensions that can gather browsing data, steal email contents, and turn browsers into proxies for malicious activities.
Fake "Save to Google Drive" Browser Extension
The fake "Save to Google Drive" browser extension is another key feature of Kotalq App's payload. This extension may look legitimate at first glance, but it serves several malicious purposes:
- It can modify the appearance and behavior of web browsers, potentially redirecting users to malicious websites or injecting unwanted ads.
- It gathers browsing-related information, compromising user privacy and security.
- It may also request additional permissions, which can be exploited to further infect the system or hijack browser resources.
Additional Risks
The Kotalq App installer is often bundled with other suspicious software, such as adware and browser hijackers. This bundling increases the number of potential threats that can be introduced to a system, including:
- Adware, which generates intrusive pop-ups and redirects, often causing a significant slowdown of system performance.
- Browser hijackers, which alter browser settings without the user's consent, typically redirecting searches to malicious sites or injecting additional advertisements.
Guide to Removing Kotalq App
Step 1: Install SpyHunter
- Download SpyHunter from the official website and install the program following the on-screen instructions.
Step 2: Perform a Full System Scan
- Open SpyHunter and initiate a full system scan to detect any traces of Kotalq App and associated malware.
- SpyHunter will scan your system for known malware signatures and detect potentially unwanted applications, including Kotalq App, Legion Loader, and any additional threats.
Step 3: Review Detected Threats
- Once the scan is complete, SpyHunter will display a list of detected threats.
- Review the results and look for any entries related to Kotalq App, Legion Loader, or the "Save to Google Drive" extension.
Step 4: Remove Identified Threats
- Select all the detected threats and proceed with the removal process. SpyHunter will safely remove Kotalq App, Legion Loader, and any other associated malware from your system.
Step 5: Restart Your System
- After the removal process is complete, restart your computer to ensure all changes are applied and your system is fully cleaned.
Step 6: Additional Scan
- Run another scan to ensure no remnants of Kotalq App or Legion Loader remain on your system.
Preventive Measures to Avoid Future Infections
- Be Cautious with Software Installations:
- Always download software from trusted sources and avoid downloading from unverified websites.
- During installation, carefully review any additional software bundled with the installer. Deselect any unwanted programs.
- Use Reputable Security Software:
- Install a comprehensive antivirus program like SpyHunter to regularly scan your system for potential threats.
- Enable real-time protection to prevent malware from entering your system in the first place.
- Avoid Clicking on Suspicious Pop-ups: Be wary of pop-up ads, especially those that claim your system is infected or prompt you to install software. These are often used to distribute PUAs like Kotalq App.
- Update Your Browser and Extensions Regularly:
- Keep your web browser and its extensions up to date to avoid vulnerabilities that could be exploited by malware.
- Only install extensions from trusted sources and regularly review installed extensions to remove any suspicious ones.
Conclusion
Kotalq App is a significant threat that can lead to multiple malware infections, severe privacy breaches, and financial losses. Its role as a dropper for Legion Loader malware makes it particularly dangerous, as it paves the way for additional malicious programs, including trojans, ransomware, and cryptocurrency miners. However, by using reliable security software like SpyHunter and following the recommended preventive measures, users can protect themselves from this and similar threats. Stay vigilant, and always practice safe browsing habits to avoid falling victim to such attacks.
