Error code 0x800700E1 usually appears when you copy a file or install third-party software on Windows 10. The prefix of this stop code indicates that the operation was not completed successfully. However, the software is never malicious or contains no viruses, although the system displays a message indicating that the file contains a virus or potentially unwanted software.

The 0x800700E1 error is the result of Windows Defender, which usually prevents the installation of valid software due to special caution. In addition, the problem may cause you concern about damaged system files. If something goes wrong when transferring files from a USB flash drive to an external hard drive, confusion may also occur. You will encounter several methods to contain this error, such as – disabling Windows Defender, customizing in Regedit, changing the policy setting.

Using DISM Scan

In Administrator: Command Prompt, type the following commands.
Press Enter after each command:

Disabling the Security Suite

Windows Defender or another third party suite may interrupt the backup process due to a false alarm and trigger error code 0x800700E1 – this is regularly caused by unsigned applications, cracked executables and game changes.

If you are absolutely sure that this particular problem is not caused by malware or PuP, you can simply disable Windows Defender before running the backup to prevent the security scan from triggering this error code.

This process has been confirmed by a number of concerned users as running on Windows 10. If you are using a third-party AV suite, disable real-time protection or uninstall the security program and the remaining files.
