## 1. Use a Secure Mode or Private / Incognito Window

- **Why?** Browsing in a private or incognito mode helps ensure no browser plug-ins, extensions, or cached data interfere with your CoinUnited.io session. This reduces the likelihood of malicious add-ons compromising your information.

- **Quick Shortcuts:**
  1. **Chrome:** Press **Ctrl + Shift + N** to open a new incognito window.
  2. **Firefox:** Press **Ctrl + Shift + P** to open a new private window.

## 2. Double-Check Withdrawal / Deposit Addresses

- **Why?** Phishing and malicious redirects can alter cryptocurrency addresses, causing funds to be sent to the wrong destination.
- **Steps to Protect Yourself:**

1. Always **save** your withdrawal/deposit address in a secure place (like a notepad document).
2. **Copy and paste** the address directly from the notepad into your browser.
3. Carefully **verify** the pasted address matches what you intended to use.

- **If You Spot Any Differences:**  
  Your device might be infected by **Trojans** or **viruses** that alter copied text.

## If Your Device Is Infected:

1. **Install and Run Antivirus Software**  
   Scan your system immediately to detect and remove any Trojans or viruses.
2. **Disable Unnecessary Plug-ins/Extensions**  
   Remove unfamiliar browser extensions and software.
3. **Reinstall OS (If Needed)**  
   In severe cases, back up critical files, then format your disk and reinstall your operating system.
4. **Seek Professional Advice**  
   If unsure, consult information security experts for further guidance.

## Additional Security Tips

- **Keep Software Updated**: Regularly update your operating system, browsers, and antivirus programs.
- **Use Strong, Unique Passwords**: Avoid reusing passwords across multiple services.
- **Enable Two-Factor Authentication (2FA)**: Add an extra layer of protection to your CoinUnited.io account.
- **Be Cautious of Public Wi-Fi**: Only use trusted networks, or set up a VPN when traveling.
