🚨 **Quick Guide: Understanding Computer Viruses** 🚨
Hey, Cyber Guardians! 🛡️💻 Ever wondered how those sneaky computer viruses work and what damage they can do? Let’s break it down:
**What’s a Virus?** 🦠
A computer virus is malicious software designed to spread from one system to another, latching onto legitimate files or programs. It can alter, corrupt, delete files, disrupt systems, steal sensitive info, or even grant unauthorized system access.
**How Do They Spread?** 🌐
Viruses rely on human actions (think opening a bad email attachment or downloading infected files), removable media, network vulnerabilities, drive-by downloads, or social engineering tactics.
**Know Your Enemies: Types of Viruses** 🔍
1. **Boot Sector Virus:** Infects the boot sector, loading into memory upon boot.
2. **Browser Hijacker:** Modifies browser settings to control browsing behavior.
3. **Direct Action Virus:** Attaches to executable files, activating upon ex*****on.
4. **Encrypted Virus:** Uses encryption to evade detection by antivirus software.
5. **File Infector Virus:** Infects executable files, activating upon ex*****on.
6. **Macro Virus:** Targets documents/spreadsheets containing macros.
7. **Multipartite Virus:** Infects both the boot sector and executable files.
8. **Polymorphic Virus:** Changes its code to avoid detection.
9. **Resident Virus:** Embeds in memory, remaining active post-ex*****on.
10. **Web Scripting Virus:** Exploits web scripting languages to execute malicious code.
**Stay Protected** 🛡️
Always be vigilant with emails, downloads, and websites. Keep your antivirus updated and back up your data regularly.
