404 Keylogger virus removal guide
What is 404 Keylogger?
404 Keylogger is software designed to record key strokes, recover account passwords and otherwise monitor users' activity. 404 Keylogger is promoted as a legitimate tool for various businesses and for companies to track client/customer activity (with consent) and an "educational" tool to aid learning about keyloggers. Note that this type of software is very popular amongst cyber criminals. Certain promoted features such as anti-detection and anti-analysis capabilities are suspicious and suggest that 404 Keylogger is also intended for malicious use.
404 Keylogger can detect whether it is running in a virtual or 'sandboxed' environment, which obfuscates its presence and hinders analysis. This program can also download and execute files, and hence can be used to cause chain infections. It can thus be used to download/install additional malware, however, the primary function of 404 Keylogger is stealing data. It can monitor the infected device's user activity to a certain level. One of the capabilities this keylogger possesses is taking screenshots, thereby capturing a view of the screen. The main feature of keyloggers is, as the name implies, keylogging. They can record all typed information. Cyber criminals typically use this to target the credentials (i.e., log-ins and passwords) of various accounts such as emails, social networking, social media, cloud storage, e-commerce (online store), financial and so on. Through stolen communication accounts, criminals can impersonate the user and ask their contacts/friends for loans and/or share dangerous files to spread the infection. If sensitive and/or compromising content is found in storage accounts, it can be used for blackmail and ransom purposes. Hijacked e-commerce and financial accounts can be misused to steal banking information and/or credit card details, which in turn can be used for fraudulent transactions and online purchases. In summary, 404 Keylogger infections compromises system integrity and can result in additional infection. Furthermore, people can experience serious privacy issues, financial loss and identity theft. If it is known/suspected that 404 Keylogger (or other malware) has already infected the system, you are strongly advised to immediately use an anti-virus program to eliminate it.

Hupigon, Guildma, Pekraut and Cardinal are some examples of malicious programs capable of keylogging. Malicious software has varied capabilities, such as data exfiltration, hardware manipulation (e.g. recording audio/video through microphones and webcams, etc.), remote access and control over a system, data encryption (for ransom purposes), download/installation of additional malware, cryptomining, and so on. Regardless of how malicious programs operate, their purpose is identical: to generate profit to the cyber criminals using them. Malware infections endanger device and user safety, and therefore necessitate immediate removal.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.
Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.
