Windows 10: Does Windows Defender scan all files that are downloaded?

Just a question, does windows defender scan all files that i download and quarantine them if they are harmful? Including archives such as rar or zip?

Windows 10 Defender scanning downloaded files

Running Win10 Home 64bit on a MSI Z270-A PRO motherboard, i7-6700, 16 GB ram.
This is a new build for me and I just installed Win10 Home and did all updates.

When I download programs with Defender running, do I have to manually scan the file before installing the program?

When I tried to manually scan a downloaded program using the following method, it doesn't show results of the scan:

• Rt click the file name.
• In the pop up menu, click "Scan with Windows Defender"
• A window pops up showing "Full Scan", "Custom Scan" and "Windows defender offline scan", but no results of the individual file scan.

Thanks for any ideas.

 

Edge scans downloads with Windows Defender?

Cryptic invisible reply. I like! I actually went to the effort of working out the deciphering process of your message. It was only highlighting the text but I feel like a code breaker.

Alas, I shall continue.
Like stated SmartScreen is a feature of Windows Defender and so Windows Defender will be doing the scanning. SmartScreen is like the name suggests is just a theoretical screen that comes into action upon certain triggers. In this case the triggers for SmartScreen for Edge will be mainly downloaded files. When you download something SmartScreen for Edge will spring into action which will call Windows Defender to do the work of scanning. Any necessary action thereafter will be taken by Windows Security depending on the result of the scan.

Hi Ian,

Thanks for posting your query on Microsoft Community.

This issue might occur if you have set any task scheduler for Windows Defender.

I suggest you to delete the task for Windows defender and check if it helps.

Follow the below steps:

• 
  Search and open Schedule tasks.
  
• 
  In the left-hand menu, open the Task Scheduler Library, then select
  Microsoft >Windows >Windows Defender.
  
• 
  Double-click Windows Defender Scheduled Scan.
  
• 
  Select the Triggers panel, then select Delete.
