Malware or malicious software is any software used to infect computers or mobile systems, to hack into private information or display unwanted adverts. Malware is of numerous types. They are grouped depending on their method of attack and the result of their attack on a system.
Malware is usually designed as a non-malicious file or software, or it is attached to one. Some malware is designed to infiltrate into private computers without authorization but may not destroy any programs or files. While the most problematic of malicious software are designed to, not only hack into the system but to wreck the programs and files.
Malware is utilized by some governmental organizations and black hat hackers in pilfering personal information, business, and financial information. Most malware today are used for the purpose of financial gain. The predominance of malware in modern times is as a result of the Internet of Things which gives quick access to systems from the public domain.

This type of malware is developed with the purpose of discovering financial information and overturning the system’s resources. They could also cause ‘denial-of-service’ attack, blocking any attempts to reach that system by a computer network support. This effectively blocks the computer support from being able to recover lost files.
This is designed to enable other software to get the system’s identity information without the user’s knowledge. It sits silently on the system while the user, unaware of the threat, continues using the system until another malware is employed in accessing the computer’s files and identity software.
It is the same as Trojans or Worms. They provide a backdoor for hackers to access the system or to send SPAM.
