A keylogger (also known as keystroke logger) is a software that monitors and records each keystroke on a keyboard and saves this information in a file or remote server. The program can collect information from computers, laptops, smartphones and other mobile devices. Usually, such software is associated with spyware and is used for stealing passwords, logins, credit card information and similar information.
Keyloggers can be both, legal and illegal. Such tracking applications can be used in workplaces or researching user's behavior on computers or other gadgets. Cybercriminals often take advantage of such “spying” programs too to steal personal information.
If you suspect that your keystrokes might be recorded and used for illegal purposes, you should not hesitate and check the system with a reputable anti-malware software. A professional and up-to-date tool should detect and remove keylogger immediately. After that, changing all your passwords and monitoring bank transactions are crucial tasks to protect your privacy.
The difference between hardware and software keyloggers
There are two types of keyloggers:
Keyloggers can be divided into two categories – legitimate and malicious.
The hardware keylogger is a small physical device that can be dropped between the keyboard’s plug and the computer’s keyboard port. A hardware keylogger records all keystrokes and saves them into own memory. Such a device does not rely on a particular software or a driver. Therefore, it can work in different environments. However, it does not take screenshots and can be easily found during a thorough computer inspection. Software keyloggers are divided into parasitical and legitimate applications.
Malicious keyloggers are very similar to viruses and trojans. They are used by hackers to violate user privacy. Legitimate keyloggers, also known as computer surveillance tools, are commercial products targeted mostly to parents, employers, and teachers. They allow to find out what children or employees are doing online. However, even legal programs work without the monitored user’s knowledge and consent. Malicious actors can also use them. Therefore, these tools shouldn't be classified as less harmful threats than the certain parasites.
Ilegal and malicious use of the keylogger
Practically all keyloggers seek to violate user's privacy. They can track their victims for months and even years until they are noticed. During all this time, a regular keylogger is capable of finding out as much information about the user as possible. Someone who controls a keylogger gets priceless information, including passwords, login names, credit card numbers, bank account details, contacts, interests, web browsing habits and much more. All this information can be used to steal the victim's documents and the money.
The main features of the keyloggers
- Logging keystrokes on the keyboard.
- Taking screenshots of the user's activity on the Internet at predetermined time intervals.
- Tracking user's activity by logging window titles, names of launched applications, and other specific information.
- Monitoring user's online activity by recording the addresses of visited websites, entered keywords and other similar data.
- Recording login names, details of various accounts, credit card numbers, and passwords.
- Capturing online chat conversations on instant messengers.
- Making unauthorized copies of outgoing and incoming e-mail messages.
- Saving all collected information into a file on a hard disk, and then silently sending this file to a required e-mail address.
- Complicating its detection and removal.
Keyloggers cannot be compared with regular computer viruses. They do not spread themselves as these threats do and, in most of the cases, must be installed as any other software.
Methods used to spread and install keyloggers on the system
As you already know, keyloggers can be legal and illegal. However, both of them are usually installed without the user's knowledge, but this task achieved using different methods.
- A legitimate keylogger can be manually installed on the system by its administrator or any other user who has needed privileges for this activity. A hacker can break into the system and setup his keylogger. In both cases, a privacy threat gets installed on the system without user’s knowledge and consent.
- Malicious keyloggers can be installed on the system with the help of other parasites, such as viruses, trojans, backdoors or other malware. They get into the system without user's knowledge and affect everybody who uses a compromised computer. Such keyloggers do not have any uninstall functions and can be controlled only by their authors or attackers.
In most of the cases, keyloggers affect computers running Microsoft Windows operating system. However, all viruses are constantly updated, so there is no guarantee that they are not capable of hijacking other popular platforms.
Examples of the most dangerous keystroke loggers
There are lots of different keystroke logging applications, both commercial and parasitical. The following examples illustrate typical keylogger behavior.
All In One Keylogger
AllInOne keylogger has been actively used to track users worldwide. It is an illegal tool.
All In One Keylogger is a malicious program targeted at PC users and their personal information. Typically, people who work behind it, seek to steal as much information as possible. AllInOne KeyLogger is designed to record all user's keystrokes, take the screenshots and initiate other activities. You can hardly notice this threat on your computer as it hides deep inside the system.
Ardamax Keylogger is a legitimate tool mostly used for researches. However, some of its versions have already been compromised.
Ardamax Keylogger is a legitimate program which was created for professional usage. However, cybercriminals managed to compromise 4.6 version of the program and used it for the malicious purposes. Once users downloaded the program from the official website, the program started collecting keystrokes, recording audio and using visual surveillance which was sent to the remote criminals' server.
Invisible Stealth Keylogger
Invisible Stealth Keylogger – trojan horse with keystroke-logging functions.
Invisible Stealth Keylogger is the harmful trojan horse with keystroke-logging functions. This parasite not only records every user's keystroke but also gives the opportunity for the remote attacker to have unauthorized access to a compromised computer. He or she can easily download and execute arbitrary code, steal user’s vital information (passwords, e-mail messages or bank account details). Once it collects the needed amount of data, this threat sends it to the attacker through a background Internet connection. Moreover, they can cause general system instability and even corrupt files or installed applications.
Perfect keylogger is used to collects users’ keystrokes and passwords, take screenshots and use other methods to track users.
Perfect Keylogger is a complex computer surveillance tool with rich functionality. It records all user keystrokes and passwords, takes screenshots, tracks user activity on the Internet, captures chat conversations and e-mail messages. Perfect Keylogger can be remotely controlled. It can send gathered data to a configurable e-mail address or upload it to a predefined FTP server. Although it is a commercial product, it’s even more dangerous than most parasitical keyloggers.
Remove Keylogger with reputable security software
Keylogger removal must be performed as soon as possible. As you already know, these type of programs can steal personal information and use it for further cyber crimes. Keystroke loggers might be hiding in the system and be invisible in the Task Manager. For this reason, you should use reputable anti-virus/anti-malware software to detect and eliminate this cyber threat.
Also, make sure you fix the virus damage by running a full system scan with Reimage. It will recover your system to its previous state by eliminating changes initiated by the malware. If you have some difficulties and cannot remove Keylogger from the device or fix errors that it caused, you can share your question with us using the Ask Us page.

Steps to take after keylogger removal
Once you get rid of the keylogger, you should also take care of your personal information:
- Change all of your passwords (email, social media, bank, etc.);
- Set strong and unique passwords for each account;
- Enable two-factor authentication to strengthen your accounts;
- Monitor your banking transactions and if you notice suspicious transactions, inform your bank directly;
- Install and regularly update antivirus software to make sure that any keyloggers are not trying to steal your personal information.
