What is a Computer Virus?

A computer virus is a type of malicious software (malware) that, when executed, replicates itself by modifying other computer programs and inserting its own code. This self-replication is what distinguishes a virus from other types of malware. Viruses often spread quickly, infecting systems and networks, leading to data corruption, system crashes, and other harmful effects.

How Viruses Spread

Viruses typically spread through various means, including:

  • Infected Files: Downloading or opening infected files from the internet, email attachments, or removable media.
  • Software Vulnerabilities: Exploiting security weaknesses in software or operating systems.
  • Network Propagation: Spreading through shared network resources.
  • Social Engineering: Tricking users into running malicious programs.

Types of Computer Viruses

There are several types of computer viruses, each with its own characteristics and methods of infection: — Piste: Unveiling The Meaning Of This Skiing Term

  • Boot Sector Viruses: They infect the boot sector of storage devices, becoming active when the computer starts.
  • Macro Viruses: These viruses are written in macro languages and infect documents, such as Microsoft Word or Excel files.
  • Polymorphic Viruses: These viruses change their code with each infection, making them difficult to detect using traditional antivirus methods.

Protecting Against Computer Viruses

Protecting your computer from viruses requires a multi-layered approach:

  1. Install Antivirus Software: Use a reputable antivirus program and keep it updated.
  2. Keep Software Updated: Regularly update your operating system and applications to patch security vulnerabilities.

  • Run a Full System Scan: Use your antivirus software to perform a thorough scan of your system.
  • Quarantine or Delete Infected Files: Follow the recommendations of your antivirus software to quarantine or delete any identified infected files.
