Your System Thief's : Malware Programs!

Malware, abbreviation for malicious (or malevolent) software, is a software used or created by illegitimate people to disrupt computer operation; gather sensitive or important information, or access to private computer systems. It can be in the form of code, scripts, active content and other software.

Malware includes computer viruses, worms, trojan horses, spyware, adware, and other malicious programs. By law, malware is sometimes known as a computer contaminant. Malware is not the same as defective software, which is a software that has a legitimate purpose but contains harmful bugs that were not corrected before release.However, some malware is disguised as genuine software, and may come from an official company website. An example of this is software used for harmless purpose and is packed with additional tracking software to gather marketing statistics. Malware has increased the use of protective software such as anti virus, anti-malware, and firewalls. Each of these are commonly used by personal users and corporate networks in order to stop the unauthorized access by other computer users, as well as the automated spread of malicious scripts and software.
