Using Antivirus and Firewall

Antivirus Software

What it does:

• Scans files, programs, and downloads for malware (viruses, worms, Trojans, ransomware).
• Removes or quarantines harmful files.
• Provides real-time protection against new threats.

Best Practices:

• Keep antivirus software updated so it recognizes the latest threats.
• Schedule regular scans of your device.
• Don’t disable antivirus protection, even temporarily.
• Use trusted antivirus solutions from reputable companies.

Firewall

What it does:

• Acts as a barrier between your device/network and the internet.
• Monitors incoming and outgoing traffic.
• Blocks unauthorized access while allowing safe communication.

Best Practices:

• Keep your system’s built-in firewall enabled (Windows Defender Firewall, macOS Firewall, etc.).
• For businesses, use network firewalls for stronger, centralized protection.
• Configure rules carefully (only allow trusted apps and services).

Working Together

• Antivirus protects against malicious files inside your device.
• Firewall protects against unauthorized connections from outside.

Together, they provide layered defense, making it much harder for attackers to succeed.

Key Takeaway

Always keep both your antivirus software active and updated, and your firewall enabled. This combination builds a strong first line of defense against cyber threats.
