DST.exe is blocked by Windows defender. Is it a safe file or how can I get rid of the notification

[alvdeluqq]

Windows defender tells me that a DST.exe file has been blocked. I've run a virus scan and it can't find any virus on my computer. 

This is the message from Windows Defender:

As you can see, the file seems to be located in \Device\Harddisk0\DR0. But I can't manage to find that path

Is this file something I want to run on my computer or should I get rid of it?  If I should get rid of the file how can I get rid of it?

On the other hand, searching with the file explorer I found a DST.exe located in the path: Users\aluna\AppData\Local\Temp\HPDIAGS\64819556-07a0-42c4-a925-bba17af6db61

I don't know if it is the same or not, what should I do?

When I try to open it as an administrator it says that is signed by HP...

Thank you!

Same problem here. I get this message from time to time and don't know what to do. Should we unblock that file in Windows Defender?

Did anyone ever reply to your question?  I am also having the same issue.  HELP!!!!

It should be ok, DST most likely stands for "Drive Self Test" which is part of your HP Diagnostic software tools, which is a trusted software on your PC. Try reinstalling the app and/or allowing it as needed through your antivirus scan software settings.
