If you’ve encountered the frustrating Windows Security warning “Operation did not complete because the file contains a virus or potentially unwanted software” while trying to install a game (such as a FitGirl repack), this guide will help you safely bypass the false-positive detection without compromising your system’s security.

Why Does This Error Occur?

Windows Defender (now Microsoft Defender) aggressively blocks files it suspects to be malicious—even if they’re safe. Game repacks, mods, and certain installers often trigger false positives due to their compression methods or executable wrappers.

Step-by-Step Solution

Step 1: Temporarily Allow the Blocked File

1. Open Windows Security:

• Press Win + S, type Windows Security, and open the app.

1. Go to Virus & Threat Protection > Protection History.
2. Find the blocked threat under “Threat Blocked” and click on it.
3. Select “Allow” (or “Restore”) and confirm with Yes.

Step 2: Pause Real-Time Protection (Temporarily)

1. In Windows Security, go to Virus & Threat Protection > Manage Settings.
2. Turn off the following:

• Real-time protection
• Cloud-delivered protection
• Automatic sample submission

1. Minimize Windows Security (do not close it).

Step 3: Resume the Download/Installation

• Retry downloading or installing the game. It should now proceed without interruptions.

Step 4: Add the Game Folder to Exclusions (Permanent Fix)

1. Once installed, go back to Windows Security > Virus & Threat Protection > Manage Settings.
2. Scroll down and click “Add or Remove Exclusions.”
3. Click “Add an Exclusion” and select “Folder.”
4. Navigate to the game’s installation directory (e.g., D:\Games\YourGame).
5. Click “Select Folder” to whitelist it.

Step 5: Re-Enable Windows Defender

1. Return to Virus & Threat Protection > Manage Settings.
2. Turn back on all previously disabled protections.

Important Notes & Safety Tips

✅ Only disable security features temporarily—re-enable them immediately after installation.
✅ Download from trusted sources (FitGirl repacks are generally safe, but always verify checksums).
✅ Scan excluded folders occasionally to ensure no real malware is present.

Alternative Solutions

• Use a Third-Party Antivirus (e.g., Malwarebytes) for better control over false positives.
• Check the Game’s Official Website/Forum for known issues with antivirus software.

Conclusion

By following these steps, you can safely bypass false virus warnings while keeping your system secure. If you frequently install repacks or mods, adding exclusions is the best long-term solution.

Disclaimer: Disabling antivirus protection can expose your system to risks. Only exclude files/folders you trust. FitGirl repacks are widely used but always verify their integrity via checksums or community feedback.
