What are the most common forms of malware?
Some of the most common forms of malware are explained below:
- Trojan Horses
- Computer Virus
- Phishing and Spear Phishing
- Bots and Botnets
A worm is a malicious software which similar to that of a computer virus is a self-replicating program, however, in the case of worms, it automatically executes itself. Worms spread over a network and are capable of launching destructive attacks within a short period.

The altering helps the hacker to take full control of the system and the hacker acts as the system administrator on the victim's system. Almost all the rootkits are designed to hide their existence.
A computer virus is a malicious software that hackers design to multiply. The computer virus attacks and infects existing files on the targeted system – it spreads by itself into other executable code or documents. The sole purpose of designing a computer virus is to infect vulnerable systems, gain admin control and steal user confidential data.

Keyloggers could work as a small external device connected to the PC and keyboard – it is never easily recognizable.

A bot is a self-governing program on a network (especially the Internet) which can interact with systems or users, particularly one created to act like a player in some video games.
The words ransom-malware is coined as a ransomware which is malicious software that threatens to delete or deny access to data, once it takes over the computer.
