Computer viruses are malicious software programs that are designed to replicate and spread from one computer to another. They can cause harm to a computer system by corrupting or deleting data, stealing sensitive information, or disrupting the normal functioning of the system. There are several types of computer viruses, each with its own unique characteristics and behavior.
File infector viruses: These viruses infect executable files, such as .exe or .com files, and replicate themselves by attaching to these files. When the infected file is run, the virus is also executed, allowing it to spread to other files on the computer.
Macro viruses: Macro viruses infect documents, such as those created in Microsoft Word or Excel, and replicate themselves by inserting malicious macro code into these documents. When the document is opened, the macro code is executed, allowing the virus to spread.
Boot sector viruses: These viruses infect the boot sector of a hard drive, which is the area of the drive that contains the instructions for starting the computer. When the infected computer is booted, the virus is also loaded into memory, allowing it to spread to other hard drives or disks that are connected to the computer.
Email viruses: Email viruses are transmitted through email attachments or links in email messages. When the attachment or link is opened, the virus is activated and can spread to other computers through email or other means of communication.
Worms: Unlike viruses, worms do not need to attach themselves to a host file in order to replicate and spread. They are self-replicating programs that can spread through networks, email, or other means of communication.
Ransomware: Ransomware is a type of malicious software that encrypts a victim's files, making them inaccessible until a ransom is paid to the attackers. Ransomware can be transmitted through email attachments, malicious websites, or other means of communication.
Trojans: Trojans are malicious programs that are disguised as legitimate software. They are often transmitted through email attachments or downloaded from the internet. Once activated, Trojans can give attackers access to a victim's computer, allowing them to steal sensitive information or perform other malicious actions.
In conclusion, there are several types of computer viruses, each with its own unique characteristics and behavior. It is important to protect your computer by installing antivirus software and being cautious when opening email attachments or downloading software from the internet.
