There are two types of keyloggers, based on the process applied to install and control keylogger. Software-based keylogger and another one is hardware-based keylogger
1. Software-based keyloggers

These Keyloggers are common Trojan viruses that modify the memory record of a framework to sidestep online safety. Another illustration is frame snatching based programming. This controls the structures submitted on the web and tracks all the data users put in each frame.
Software-based keyloggers are higher critical if there are extra features for every. This can be very difficult to detect that’s why it takes a lot to remove them.
2. Hardware-based keyloggers
Compared to a software-based Keylogger, hardware Keylogger doesn’t require any installing as they are as of now inside the physical usage of the PC. Keyboard keyloggers are amongst the various broadly known cases of hardware-based ones.
The Keylogger controls the keyboard keys a user presses and after that records it secretly. Another problem is the acoustics keyloggers. It can read the sounds of the keys pushed by each client. Since each sound is different, it is understandable to divine which key it is.
Keyloggers can both be evil or great. Supposing there is such an important number of classes of keyloggers out there, one should always be-be very careful. So whether you’re installing something or a device connected to your PC, better be attentive every action of the way.
