With cyber threats on the rise, securing your computer from viruses and malware is more important than ever. Whether you use your PC for work, gaming, or browsing, a single virus can compromise your data, slow down performance, or even lock you out completely.

1. Install and Maintain a Strong Antivirus Software

Step 1: Choose a Trusted Antivirus

• Popular options include Bitdefender, Norton, McAfee, Kaspersky, and Windows Defender (built-in for Windows 10/11).
• Avoid free antivirus programs with aggressive ads or limited protection.

Step 2: Keep Your Antivirus Updated

• Open your antivirus software and enable automatic updates.
• Set it to run daily scans or at least a weekly full system scan.

Step 3: Perform a Full System Scan

• Go to your antivirus dashboard and select Full Scan to detect hidden threats.
• If malware is found, follow the removal steps provided by the software.

✅ Best for: Preventing common viruses, spyware, and ransomware.
❌ Limitations: Advanced malware (rootkits) may bypass basic antivirus detection.

2. Keep Your Operating System and Software Updated

Step 1: Enable Automatic Updates on Windows & Mac

• Windows Users:
  1. Go to Settings > Update & Security > Windows Update.
  2. Click Check for Updates and enable automatic updates.
• Mac Users:
  1. Open System Preferences > Software Update.
  2. Enable Automatic Updates to keep macOS secure.

Step 2: Update Your Browsers & Plugins

• Open Google Chrome, Firefox, Edge, or Safari.
• Go to Settings > About to check for browser updates.
• Update Java, Flash, and other plugins to prevent security vulnerabilities.

✅ Best for: Closing security loopholes that hackers exploit.
❌ Limitations: Older software versions may stop receiving updates, requiring an upgrade.

3. Use Strong Passwords and Multi-Factor Authentication (MFA)

Step 1: Create Secure Passwords

• Use a mix of uppercase, lowercase, numbers, and symbols (e.g., P@ssw0rd#2024).
• Avoid using the same password for multiple accounts.

Step 2: Use a Password Manager

• Store and generate strong passwords with Bitwarden, LastPass, or 1Password.
• Avoid saving passwords in your browser for better security.

Step 3: Enable Two-Factor Authentication (2FA)

• Activate 2FA on your email, banking, and important accounts.
• Use an authentication app (Google Authenticator, Authy) instead of SMS codes.

✅ Best for: Protecting against password leaks and brute-force attacks.
❌ Limitations: If you forget your 2FA codes, account recovery can be difficult.

4. Avoid Suspicious Links and Downloads

Step 1: Verify Emails and Messages Before Clicking Links

• Red Flags in Emails & Texts:
  ❌ Urgent action required (e.g., “Your account will be closed!”)
  ❌ Unknown sender with odd email formatting
  ❌ Unexpected attachments or weird file extensions (.exe, .scr, .zip)
• If unsure, hover over links to see the real destination URL before clicking.

Step 2: Download Software from Official Sources Only

• Only download apps and software from official websites or trusted app stores.
• Avoid “cracked” software—it often contains hidden malware.

Step 3: Use an Ad Blocker & Anti-Phishing Extensions

• Install uBlock Origin (Chrome/Firefox) to block malicious ads.
• Use Bitdefender TrafficLight for extra phishing protection.

✅ Best for: Preventing ransomware, phishing, and hidden malware.
❌ Limitations: Some safe websites may block content when ad blockers are enabled.

5. Backup Your Important Data Regularly

Step 1: Use an External Hard Drive or Cloud Storage

• Cloud Options: Google Drive, OneDrive, Dropbox
• Local Backup: External HDD or SSD (Western Digital, Seagate)

Step 2: Set Up Automatic Backups

• Windows:
  1. Go to Control Panel > Backup & Restore > Set up backup.
  2. Select an external drive or network location.
• Mac:
  1. Open System Preferences > Time Machine.
  2. Choose an external drive and set hourly, daily, or weekly backups.

Step 3: Test Your Backups

• Try restoring a file from your backup to ensure it works properly.
• Keep multiple backups in different locations for extra security.

✅ Best for: Preventing data loss from ransomware or hardware failure.
❌ Limitations: Cloud storage requires internet access and may have limited free space.
