How to Fix: TeraCopy error message: "Operation did not complete ... file contains a virus", yet my antivirus did not prompt me about any detected viruses

TeraCopy error message: Operation did not complete because the file contains a virus, despite antivirus not detecting viruses.

Quick Answer: Check TeraCopy's settings to ensure 'Scan for viruses' is disabled.

The error message 'Operation did not complete because the file contains a virus' from TeraCopy can be frustrating, especially when your antivirus software has not detected any viruses. This issue affects users who are using TeraCopy to transfer files and have encountered this specific error. The lack of antivirus alerts can make it difficult to determine the cause of the problem.

This error message is particularly problematic because it suggests that the file contains a virus, which may lead to incorrect assumptions about the safety of the transferred data.

💡 Why You Are Getting This Error

  • The primary reason for this error is that TeraCopy uses its own built-in virus scanner to scan files during the transfer process. This scanner can sometimes flag clean files as containing viruses due to various factors such as file format, metadata, or other characteristics. This means that even if your antivirus software has not detected any viruses in the file, TeraCopy's scanner may still flag it.
  • Another possible reason for this error is a misconfiguration of TeraCopy's virus scanning settings. If the 'Scan' option is enabled and set to scan all files during transfer, it can lead to false positives.

🚀 How to Resolve This Issue

Disable Virus Scanning in TeraCopy

  1. Step 1: Open TeraCopy and go to the 'Settings' tab.
  2. Step 2: In the 'Settings' window, uncheck the box next to 'Scan' in the 'Advanced' section.
  3. Step 3: Save the changes and try transferring the file again.

Run a Virus Scan with Your Antivirus Software

  1. Step 1: Open your antivirus software (in this case, Avast) and check if it has detected any viruses in the file.
  2. Step 2: If no virus is detected, try transferring the file again to see if the issue persists.
  3. Step 3: Consider running a full scan of your system to ensure that there are no other potential issues.

✨ Wrapping Up

To resolve the 'Operation did not complete because the file contains a virus' error in TeraCopy, you can try disabling the built-in virus scanning feature or run a virus scan with your antivirus software. If the issue persists, it may be worth checking your TeraCopy settings for any misconfigurations and considering running a full system scan.
