Windows 10: Does the defender real time scan extend to attached drives?

I would like to know whether Windows Defender's real time scan extends to usb attached storage devices like flash drives, HDDs and SSDs?


If i transferred an infected file from a laptop HDD to USB drive and ii from USB drive to laptop HDD would Defender catch these infections assuming it can identify the malware signature?

Windows Defender: Disable real time; keep scheduled and on demand scanning

I just upgraded to Win 10 (RTM build). I have disabled the built in AV's (Defender) real time protection because I do not run it, never did and have never gotten a virus (and I've had a computer for 30 years).

I was able to disable real time scans by turning on the Group Policy's Disable Defender Policy. But this disables the application entirely. Is it possible to use this profile (which I used with Win 7's Security Essentials) with Win10 Defender:

• Real time scan off
  
• Scheduled scans (2AM) active
  
• On demand (shell integration right
  click) scans active
  

?

Or do I have to install a 3rd party scanner? I already run MBAM Premium, MBAE and EMET (those are protecting in real time, as their impact on performance is minimum), but I would really like to avoid a 3rd party AV.

TIA

 

Defender will only do periodic scanning, no real time protection

Hello,

This issue may happen if other security software, such as antivirus, anti-spyware, or anti-malware programs, are fully or partially installed on the computer. Windows Defender automatically turns off if you install another antivirus app.

Let us uncheck security messages for Virus Protection and Spyware, kindly follow the steps below:

• Press the Windows key + X, then select Control Panel.
• Click on Security and Maintenance.
• Click the Change Security and Maintenance Settings.
• Uncheck Spyware and unwanted software protection and Virus Protection.
• Click OK.
• Restart the device for the changes to take effect.

After the device restarted, make a full system scan using Windows defender.

To turn on real-time protection, do the steps below:

• Select the Start button, then select Settings.
• Click on Update & Security > Windows Defender.
• Turn on Real-time protection.

Update us on the results.

Regards.
