Intro : Detecting keyloggers,RATs,Viruses & Malicious Softwares

This tutorial mainly Focusing on how to detect if your Operating System is infected with any Virus, Keyloggers or RAT.

For this we should First understand the Functionality and meaning of all of them.
Virus : A malicious Software which Replicates itself and takes over the system and do anything for which it is programmed without user permission or will. These kind of programs are usually programmed by programmers/coders to infect a system.

Keylogger: This is a program which save all the keys pressed from the keyboard and send them to the attacker/programmer/coder/owner whom se ever it is built by. These programs focus on getting the users keylogs and to survive in the system they also includes some capablities like Virus so that they can also stealth and replicate themselve to get some more targets. A keylogger may have many capablities like a Virus. They can be of many type which includes FTP Keyloggers, Email Keyloggers, PHP keyloggers etc

RAT (Remote Admin Tool): This one is the most Advanced program in these malicious softwares because once it enters the system it will give complete control of that system to the attacker/programmer/coder/owner whom se ever it is built by. This kind of program mainly focus on waiting for the Masters Order and when ever he do any order they just have to do the same. But again in order to do such things it need to survive into the system without getting detected by the user or the admin. Such Programs include different capabilities like keylogging, Backdooring, Getting Remote Access, Web Cam Hack, Files Theft etc.
