Virus and AntiVirus

In the digital world, a constant battle rages between viruses and antivirus software. Viruses are malicious programs designed to infect and disrupt your computer, while antivirus software acts as your shield, safeguarding your system from these digital threats. Understanding both is crucial for maintaining your computer’s security.

Viruses: The Stealthy Invaders

A virus is a self-replicating program that embeds itself into other software, spreading throughout your system like a digital infection. It can cause a wide range of issues, from slowing down your computer to stealing sensitive information.

How Viruses Spread:

  • Email attachments: Opening infected attachments can trigger a virus.
  • Infected websites: Visiting compromised sites can download viruses without your knowledge.
  • Removable media: Plugging in infected USB drives or other devices can transfer viruses.

Warning Signs of a Virus Infection:

  • Unexpected pop-up messages
  • Slow computer performance
  • Files disappearing or becoming corrupted
  • Programs crashing frequently
  • Changes to your browser homepage or search settings

Antivirus Software: Your Digital Defender

Antivirus software is your first line of defense against viruses. It scans your system for known threats, quarantines or removes infected files, and actively monitors for suspicious activity.

Key Features of Antivirus Software:

  • Real-time scanning: Continuously scans files as you open or download them.
  • Scheduled scans: Performs in-depth scans at regular intervals.
  • Virus definition updates: Regularly updates its database of known viruses to stay effective.
  • Heuristic analysis: Detects new or unknown viruses based on suspicious behavior.
