Understanding Computer Viruses: How to Protect Your System

In today's interconnected digital landscape, the threat of computer viruses looms large, posing risks to personal data, system integrity, and overall cybersecurity. Here's a comprehensive guide to understanding computer viruses and practical steps to safeguard your system:

What is a Computer Virus?

A computer virus is a malicious program designed to replicate and attach itself to other programs or files, infecting the system without the user's knowledge. These viruses can spread from one host to another through various means, including sharing infected files, downloading from untrusted sources, and email attachments.

Ways Viruses Enter Computers:

• Email Attachments: Opening email attachments with suspicious file extensions (.exe, .vbs, .shs, etc.) can introduce viruses into your system.

• Downloading from Untrusted Sites: Virus-infected files or programs may lurk in downloads from untrusted websites, compromising system security.

• Removable Media: Viruses can spread via USB, CD, or DVD drives when files are copied or downloaded from infected removable media.

• Downloading Games: Malicious programs may hide in game files, posing a threat when downloaded or installed.

• File Sharing: Sharing files from infected computers to others can inadvertently introduce viruses into unsuspecting systems.

Signs of a Computer Virus:

• Sluggish system performance
• Frequent crashes or freezes
• Unresponsive applications
• Inaccessible disk drives
• Unusual error messages
• Distorted menus and dialog boxes

Prevention Measures:

• Check Attachments: Always scan email attachments before opening them, and ensure they're from known users.

• Verify Extensions: Avoid downloading files with double extensions and verify file extensions before downloading.

• Browser Settings: Configure browser settings to permit access only to trusted websites.

• Exercise Caution: Ignore emails from unknown users and refrain from downloading files from unfamiliar sources.

• Use Antivirus Software: Employ reputable antivirus software, keep it updated, and scan files before downloading.
