Unraveling the Digital Nemesis: Understanding Computer Virus
In hyperconnected world, our lives are increasingly intertwined with the term computer virus has become part of our daily lexicon. But what exactly is a computer virus? How does it work, and what kinds of havoc can it wreak? In this article, we will delve into the fascinating and often perilous realm of computer viruses, exploring different types, their impact, and how to safeguard against these digital adversaries.

Understanding Computer Viruses
A computer virus is a type of computer malware, a malicious software program designed to replicate itself and spread to other computers. Just like biological viruses infect living organisms, computer viruses infect digital systems, causing various degrees of harm. These nefarious pieces of code attach themselves to legitimate files or programs, thereby gaining access to a user’s computer system.
Types of Computer Virus
- File Infector Viruses: These are perhaps the most common types of computer viruses. They attach themselves to executable files and, once the infected file is run, the virus can replicate and spread to other files and programs on the same computer. Famous examples include the CIH virus and the Sasser virus.
- Boot Sector Viruses: These viruses target the master boot record of a computer’s hard drive or removable storage device. When the infected device is accessed or booted, the virus loads into memory, giving it control over the computer’s operation. The infamous Stoned virus falls into this category.
- Macro Viruses: These viruses primarily infect documents, such as those created in Microsoft Word or Excel, by embedding
