What is malware?

Malware, short for malicious software, is any type of software designed to harm, disrupt, or damage computer systems, networks, or devices. Malware can be created for a variety of purposes, such as stealing sensitive information, gaining unauthorized access to systems, or damaging or destroying data.

Some common types of malware include viruses, worms, Trojan horses, ransomware, spyware, and adware. Each type of malware has its own specific characteristics and methods of infection.

Viruses are programs that infect other files on a computer and can spread to other computers via networks, email attachments, or infected websites. Worms are similar to viruses but can spread independently, without the need for a host file.

Trojan horses are programs that appear to be legitimate but contain hidden malicious code. Ransomware is a type of malware that encrypts the victim’s files and demands a ransom in exchange for the decryption key.

Spyware is a type of malware that is designed to spy on the victim’s activities, such as monitoring their keystrokes or stealing sensitive information. Adware is a type of malware that displays unwanted advertisements on the victim’s computer.

To protect yourself from malware, it’s important to use antivirus software, keep your software and operating system up to date, and be cautious when downloading or installing software from the internet. Additionally, avoid clicking on suspicious links or opening suspicious attachments in emails or messages.
