Computer viruses, also known as malware, are harmful software programs that are designed to infiltrate and damage computer systems. They are called viruses because they are able to replicate and spread from one computer to another, much like how biological viruses spread from one person to another.
There are many different types of malware, including viruses, worms, Trojan horses, ransomware, and spyware. Each type of malware has its own unique characteristics and methods of infection, but they all have the potential to cause serious harm to a computer system.
Viruses are perhaps the most well-known type of malware. They are small pieces of code that are attached to legitimate programs or files and are designed to execute when the host program is run. Once a virus has infected a computer, it can replicate itself and spread to other computers through shared networks or removable media.
Worms are similar to viruses in that they can replicate and spread, but they do not need a host program to execute. Instead, they are self-contained programs that are able to travel through networks and infect multiple computers.
Trojan horses are malware that are disguised as legitimate programs or files. They are often spread through email attachments or downloaded from websites. Once a Trojan horse has been installed on a computer, it can be used to gain access to the system and steal sensitive information or perform other malicious actions.
Ransomware is a type of malware that encrypts a victim's files and demands a ransom from the victim to restore access. It is often spread through phishing emails or through malicious websites.
Spyware is malware that is designed to collect information about a person or organization without their knowledge. It can be used to track a person's online activities, steal sensitive information, or display unwanted advertisements.
In conclusion, computer viruses, also known as malware, are harmful software programs that are designed to infiltrate and damage computer systems. There are many different types of malware, each with its own unique characteristics and methods of infection, but they all have the potential to cause serious harm to a computer system.
