Bit by a Bug: A Detailed Look into the World of Computer Viruses
Have you ever wondered what happens when your computer gets infected by a virus? Imagine this: you’re working on an important project, and suddenly, your screen starts displaying strange messages. Your computer is not responding, and you’re left feeling frustrated and worried. This is when you realize that your computer has been bit by a bug, a computer virus to be precise.
Understanding Computer Viruses
A computer virus is a type of malicious software that is designed to infect your computer and cause harm. These viruses can be spread through various means, such as email attachments, infected websites, and removable storage devices. Once a virus infects your computer, it can replicate itself and spread to other devices on your network.
There are several types of computer viruses, each with its own unique characteristics:
| Type of Virus | Description |
|---|---|
| File Infector | Attacks executable files, such as .exe and .com files, and spreads by attaching itself to these files. |
| Macro Virus | Infected documents that contain macros, such as Microsoft Word and Excel files, and spreads by email or removable storage devices. |
| Boot Sector Virus | Infected the boot sector of a hard drive or floppy disk, and spreads by copying itself to other boot sectors. |
| Polymorphic Virus | Changes its code every time it replicates, making it difficult to detect and remove. |
How Viruses Spread
Computer viruses can spread in various ways, and it’s important to understand these methods to protect your computer:
- Email Attachments: Viruses can be spread through infected email attachments. When you open an infected attachment, the virus can spread to your computer and other devices on your network.
