Malware - Malicious Software
If you are reading this, it's certain that you have a computer, and if you have used a computer, I am sure you have found malware or a virus inside your PC atleast once. So let us see what exactly is a malware?
Malware, short for malicious software, is software used or created by hackers to disrupt computer operation, gather sensitive information, or gain access to private computer systems. It can appear in the form of code, scripts, active content, and other software. 'Malware' is a general term used to refer to a variety of forms of hostile, intrusive, or annoying software.It includes computer virus, worm, spyware, adware and other malicious code/script which is not good for us.
Many early infectious programs, including the first internet worm (morris worm) were written as experiments or pranks. Today, malware is used primarily to steal sensitive personal, financial, or business information for the benefit of others.Malware is sometimes used broadly against government or corporate websites to gather guarded information, or to disrupt their operation in general. However, malware is often used against individuals to gain personal information such as social security numbers, bank or credit card numbers, and so on.
Before Internet access became widespread, viruses spread on personal computers by infecting the executable boot sectors of floppy disks. By inserting a copy of itself into the machine code instructions in these executables, a virus causes itself to be run whenever a program is run or the disk is booted. Early computer viruses were written for the Apple II and Macintosh, but they became more widespread with the dominance of the IBM PC and MS-DOS system. Executable-infecting viruses are dependent on users exchanging software or boot-able floppies, so they spread rapidly in computer hobbyist circles.
