Malware short for malicious software . malware is a piece of software that is designed to disrupt operation , gather information , gain unauthorized access to system resources, and for exploitation purposes. The malware is a general term used by a computer professionals to mean a variety of forms of hostile , intrusive, or annoying software or programming code.

Indications of Virus attack Hard drive is accessed even when not using the computer. Computer freezes frequently or encounters errors. Computer slows down when programs starts. Files and Folders are missing (god has to know what happened to files). Unable to load operating system files. Browser window freezes.
When computer get infected by Viruses Dont having proper antivirus application. Not updating antivirus and operating system and applications. Installing pirated software's and rouge applications. Opening an infected E-Mail attachments.

What is a Worm A computer worm is a self-replicating malware which uses a computer network to send copies of itself to another computer. However, a computer worm does not need to attach itself to a program in your system like a computer virus does in order to function. A computer worm generally localizes its damage to the computer network by causing increased bandwidth(only applicable to old worm types )
Indications of worm attacks Unusual network traffic in pc Not able to visit websites due to bandwidth is flooded by worm. Unusual files in network shares. Unable to update antiviruses.
How Worm spreads Peer 2 peer (p2p) Infected USB Network Emails networks like devices. shares. uTorrent.

Rootkit Rootkit is a stealthy type of malware designed to hide its existence from processes viewer and other monitor software's.
Types of rootkits There are two different types of rootkits. they are : User Mode rootkit User Mode Kernel Mode rootkit Supervisor / Kernel Mode
Backdoors A Backdoor is a way in to the system that allows an attacker to access the victim machine. after penetrating the victim machine the attacker installs the backdoor in it. it used to access the victim machine. Example: NetCat
Backdoor !!!! Hey got the backdoor. PWNED
Trojan Trojan is a piece of software which contains both legitimate code and malicious code. performs covert and overt actions. Frequently embedded in applets, games and email attachments. Examples Beast ProRat
