Other common names to indicate Keylogger are: Keygrabber, keyboard capturer, keystroke logger.

1. The different types of Keylogger
They are divided into two large families:
- Hardware, these are devices that are often inserted between the keyboard and the PC, so as to intercept and store everything that is written. They are impossible for the PC to detect, and it's up to you to verify that your keyboard is directly connected to the PC. There are also wireless Keyloggers, but they are much rarer and more expensive and allow you to intercept the packets, which the keyboard sends to the PC via wireless connection (bluetooth).
- Software, these are small programs that are installed on a PC and that can store everything that is typed, even the words we delete. Computers are not the only device that can be spied on, given that there are software Keyloggers also for mobile devices (Android and iOS smartphones and tablets), to store what is typed on the keyboards of our smartphones and tablets. Virtual Keyloggers are obviously considered malware (they are undoubtedly malicious software) and are detected and blocked by some antimalware and antivirus.
2. The best hardware keyloggers
Online there are many hardware Keygrabber, USB and not. There are different shapes and sizes. In this paragraph we will deal with the most interesting models available on Amazon.
KeyGrabber USB Keylogger 2GB
It is a very simple to use and very interesting USB solution, once inserted into the USB port and inserted into the output, it will begin to record all the activity of your keyboard. Compared to other very cheap solutions it offers well 2 GB of internal memory, which are a huge quantity for a device of this kind, can in fact store two billion keystrokes (equivalent to about one million pages). The simple installation and of course compatible with all systems and all USB keyboards (even the Wireless ones with the receiver, in this case the device must be inserted between the receiver and the PC).
AirDrive Keylogger Pro
Similar to the previous model, but to recover data from this, just connect via WiFi. This small device in fact creates a WiFi network to which you can connect to retrieve the data entered, instead of having to physically remove it from the computer on which it is installed.
KeyGrabber PS / 2 Keylogger 4MB
If you are dealing with an old keyboard with a PS / 2 connection, you must choose a suitable Keygrabber, this works like the first model, that is, it records everything that is typed in its internal memory. It must be inserted between the keyboard and the PC and compatible with every operating system and every keyboard. Disguises easily as a keyboard adapter.
Airdrive KEYLOGGER Pro cable
It is a very particular model, it has the shape of an innocent USB extension, instead it contains a WiFi Keygrabber, which works similarly to the AirDrive Keylogger Pro that we have described above.
Other interesting, cheap and original models are also found on eBay.
3. How to defend yourself against hardware Keyloggers
As mentioned previously in the description of the various models on the market, defending yourself simply, if you suspect that you are being spied on, you must check that your keyboard (or its receiver if it is a Wireless model) is directly connected to the PC. Do not trust extension cables or even PS2 USB converters, where you could hide a Usb or Ps2 keylogger.
In addition, if you are suspicious about a hardware keylogger, it may be necessary to check inside the keyboard, especially if it is easily removable. In these cases, there are many keyboards tampered with with a Keylogger inserted inside. If you suspect that you are being spied on, but do not find any physical device between the keyboard and the PC, you may instead be the victim of a software Keylogger, a topic covered in the next paragraph.
4. The best free Keylogger software
There are several free keylogger software type that detect and store everything that is typed on the keyboard. These softwares not only store everything you see typed on the screen, but also what we delete and rewrite or the typing of function keys or arrows.

5. How to defend yourself against software Keyloggers
Software keyloggers are insidious to track down, often it is good to use some antikeylogger software, which you find inside good software and antivirus.
An alternative method to find them using the task manager, which informs you of all the software started on your system. If you look between applications and running processes it will be easy to find unknown apps that are always running, unless this is disguised as a common process like svchost.exe.
If you cannot locate a software keylogger, but are convinced that it is present on your computer, the only way to get rid of it is to format and reinstall the operating system.
An inconvenient, but still effective method of making life difficult for a software keylogger is to use the virtual keyboard of the PC, to enter the most important data such as sensitive passwords. Most of the keyloggers in fact cannot steal the typing through this method, so it would be necessary instead a software that records a video of the screen, software much easier to discover.
Protect yourself from a Keylogger, as you have been able to understand very important to protect your privacy from spies, jealous or malicious friends, as the data stolen can be of any kind, from the normal passwords of the accounts of Google, Paypal, Amazon to bank data, such as credit cards, access to Poste Italiane or other banks' websites or simply our conversations with family, friends, relatives or people you just met on the net.
