How do computer viruses work?
A computer virus is a code or program that is designed to replicate itself and corrupt a computer system. Viruses can be spread in a number of ways, including via email attachments, infected websites, and USB drives. Once a computer is infected with a virus, the virus can wreak havoc on the system, including deleting files, corrupting data, and causing the system to crash.

Viruses can be spread in a number of ways, including via email attachments, infected websites, and USB drives. Once a computer is infected with a virus, the virus can wreak havoc on the system, including deleting files, corrupting data, and causing the system to crash.
There are a number of different types of computer viruses, including boot sector viruses, file-infecting viruses, macro viruses, and Trojan horses. Each type of virus has its own method of replication and infection.
Boot sector viruses infect the boot sector of a hard drive, which is the part of the drive that contains the code that starts up the operating system. When the computer is turned on, the boot sector virus is activated and begins to replicate itself, infecting other parts of the hard drive. Boot sector viruses can be difficult to remove, as they can infect the master boot record, which contains information about the location of the operating system files.
File-infecting viruses infect executable files, which are programs that can be run on a computer. When the infected file is run, the virus is activated and begins to replicate itself, infecting other files on the computer. File-infecting viruses can be spread via email attachments or downloaded programs.
Macro viruses infect files that contain macros, which are sets of instructions that automate tasks in programs such as Microsoft Word or Excel. Macro viruses are typically spread via email attachments. When the infected file is opened, the virus is activated and begins to replicate itself, infecting other files on the computer.
Trojan horses are programs that appear to be benign but actually contain malicious code. Trojan horses can be spread via email attachments or downloaded programs. When the Trojan horse is executed, the virus is activated and begins to perform its malicious actions, such as deleting files, corrupting data, or stealing information.
Once a computer is infected with a virus, the virus can replicate itself and spread to other computers. Viruses can also cause the computer to crash or delete files. In some cases, viruses can be difficult to remove, and may require the use of a professional virus removal tool..Official source
The history of the world’s most dangerous computer virus
In the Beginning…
The world’s most dangerous computer virus is known as the “ILOVEYOU” virus. This virus was created in the Philippines by a student named Onel de Guzman. de Guzman released the virus on May 4, 2000, as a proof-of-concept for a school project.
The ILOVEYOU virus quickly spread around the world, infecting millions of computers. The virus caused billions of dollars in damage and was responsible for the creation of the first major botnet.
The ILOVEYOU virus was a destructive virus that did not replicated itself. However, it did spread quickly by email. The virus would send itself to everyone in the victim’s address book. The email would have the subject “ILOVEYOU” and would contain an attachment named “LOVE-LETTER-FOR-YOU.TXT.vbs”.
Once opened, the attachment would execute a Visual Basic script which would overwrite key system files and send the ILOVEYOU virus to everyone in the victim’s address book. The virus would also change the file extensions of common file types to make them unreadable.
The ILOVEYOU virus caused billions of dollars in damage and was responsible for the creation of the first major botnet. The botnet, known as the “Love Bug botnet”, was used to launch denial-of-service attacks and to send spam.
In the aftermath of the ILOVEYOU virus, several anti-virus companies were created. These companies created software that would protect computers from viruses and remove infected files.
The ILOVEYOU virus was a major wake-up call for the computer industry and led to the development of better security measures. However, it also showed that even well-meaning people can create dangerous software.
What is a Virus?
A virus is a piece of code that is designed to replicate itself and spread to other computers. viruses can be spread by email, downloads, USB drives, and other means.
Most viruses are harmless and only cause minor annoyance. However, some viruses can be very destructive. The ILOVEYOU virus is an example of a destructive virus.
What is a Botnet?
A botnet is a network of infected computers that can be controlled by a hacker. Hackers can use botnets to launch denial-of-service attacks, send spam, and commit other crimes.
The Love Bug botnet was created by the ILOVEYOU virus. The botnet was used to launch denial-of-service attacks and to send spam.
What is Denial-of-Service Attack?
A denial-of-service attack is an attack that prevents legitimate users from accessing a system. Denial-of-service attacks are often launched using botnets.
The Love Bug botnet was used to launch denial-of-service attacks. These attacks overwhelmed websites with traffic, preventing legitimate users from accessing the site.
What is Spam?
Spam is unsolicited email that is sent in bulk. Spam is often used to promote products or services. However, spam can also be used to spread viruses or to commit other crimes.
The Love Bug botnet was used to send spam. The spam messages contained the ILOVEYOU virus.
