How to Enable or Disable Scan Archive Files by Windows Defender in Windows 10

information   Information
Windows Defender helps protect your PC against malware (malicious software) like viruses, spyware, and other potentially unwanted software. Malware can infect your PC without your knowledge: it might install itself from an email message, when you connect to the Internet, or when you install certain apps using a USB flash drive, CD, DVD, or other removable media. Some malware can also be programmed to run at unexpected times, not only when it's installed.

You can set a group policy that allows you to manage whether or not Windows Defender scans for malicious software and unwanted software in archive files such as .ZIP or .CAB files.

This tutorial will show you how to enable or disable if Windows Defender will scan archive files such as .ZIP or .CAB files in Windows 10.

You must be signed in as an administrator to enable or disable to scan archive files.
