What is malware?
Malware is an aggregate phrase for malicious software. It is meant to harm or exploit any programmable device, service, or network. Cybercriminals generally utilize it to extract data that they may exploit to gain a financial advantage over victims. The possibilities of what type of information can be hacked are virtually limitless. The data might include everything from financial information to healthcare records to personal emails and passwords.
Types of malware:
Trojans:
The Trojan malware is sent via email attachments and they are disguised to look genuine. When a user downloads and runs the associated file, the malware begins to damage the system. An attacker can also distribute trojan as a payload using freeware and shareware servers through the Internet. Once installed, it causes issues such as terminating background system activities, destroying data from hard drives, and distorting file allocation systems.

Spyware is any program that, without your knowledge or permission, installs itself on your computer and begins secretly monitoring your internet activities. It is a type of malware that collects information on a person or organization invisibly and then distributes it to other parties.
Worms:
After breaching a system, a computer worm is a subtype of Trojan horse malware that may distribute or self-replicate from one computer to another without human intervention.
Ransomware:
Ransomware is a sort of virus that encrypts files, data, or computers. They threaten the owner of wiping or destroying the data if they do not pay the ransom.
