Windows 10: i just noticed that Tamper protection is turned off

does that mean that I was running my windows 10 without antivirus ?
im using windows 10 pro and the default windows 10 anti virus

do I need to do a full Scan ?
im using the PC as a server only and it is connected to the Internet

Defender Tamper Protection/1903

Moderators: This thread deals with Defender Tamper Protection setting and 1903. If this would be better served in a different location, please feel free to move the post.

Just wondering if anyone who installed 1903 is having any unusual issue with Defender's Tamper Protection.
Here's the blow-by-blow.....

1. Friend and I were running 1809 and installed 1903 via Update Assistant on Tuesday, May 21st. No issues and Defender Tamper Protection was on (default setting).
2. Two days later, the 23rd, friend gets alert that Tamper Protection is off. She turned it on and it seems to be holding.
3. Today, I get the alert Tamper Protection is off and I turned it on. So far, it's holding.

I have no idea why Tamper Protection would turn off. Both computers are clean -- no viruses, trojans, malware or adware. We do not mess around in the registry and there is absolutely no third-party antivirus on either machine.

For now, I'm taking a wait-and-see if Tamper Protection turns off again. I don't know if it's a 1903 bug or not. Any ideas or suggestions would be appreciated.

Hello Pauly, *Smile

It is recommended to leave tamper protection turned on to help prevent Windows Defender from being turned off from anything or anywhere other than directly from Windows Security.

Tamper protection in 1903?

No. Tamper protection means you can only make changes from within the Windows Security app. You can still turn off real time protection in the Windows Security app while tamper protection is in force.
