Trojan:O97M/DPlink.A file infection


Recommended Posts

Hey there!

This is more of just asking for Malwarebytes Staff/ Professional's opinion on an issue. On July 4th, I scanned my computer with Malwarebytes Premium and the Anti-rootkit beta; nothing was found each time. When I did a full scan of my computer with Windows Defender just to make sure, it says I was infected with "Trojan:O97M.Dplink.A". When I saw this I started to do some research on this trojan, but couldn't find any info other than a reddit thread talking about it and Microsoft's own entry on the trojan. I posted this to the Microsoft Community website asking if it was a false positive, but didn't really get a straight answer from them. I'll post it here because it goes into detail what happened; sorry that it's lengthy, but I like to try and be as thorough as I can be and I don't want to post links leading out of the forum: 

Hello!

I've been trying to figure this out all day; on my desktop earlier today, Windows defender flagged a file associated with the Immersive Control Panel - 'Control Panel a.k.a. ControlPanel.settingcontent-ms' - as 'Trojan:O97M/DPlink.A' in my user files and in the 'Windows.Old' files (I'd just reformatted and updated to 1803 about two weeks ago). This seemed strange since I've only logged into my Gmail, Youtube and Amazon since last night and haven't downloaded anything or even opened up an email, so I really haven't been in a position to have been infected by anything. Also, I had scanned my computer with Windows Defender last night too, and nothing came up when I did that. Windows Defender had deleted the file, so I don't have it on my computer anymore to send, if you needed it. I've run a full scan on my laptop and my father's laptop as well; WIndows Defender flagged the same exact file in the same exact location as the same Trojan I named above each time. On VirusTotal, I've noticed that Microsoft (Windows Defender) is the only Antivirus/Antimalware that's flagging it as a malicious XML file, labeling it 'Trojan:O97M/DPlink.A' leading me to suspect that this is a false positive. After a whole day of scouring the internet, I wanted to ask the Microsoft Community if this is indeed a threat or is Windows Defender detecting a false positive?

On a side note, W.D. deleted the suspected file off my laptop as well, but I do have a screenshot of where it detected the suspected file; I'll attach it for reference. I do have the suspected file still on my father's laptop; windows defender is doing a full scan with the most recent virus definitions now as opposed to earlier today and the same file is not being flagged anymore. On all the machines I've scanned I ran a full scan with Malwarebytes Premium before running Windows Defender; Malwarebytes didn't detect anything on any computer during any scan, even when I had it select the exact file in question.

[Screenshot is attached below]

To summerize, I'm wanting to know if the file Windows Defender flagged is truly malicious or just a false positive? Given how my desktop and my laptop have deleted ControlPanel.settingcontent-ms from 'windows.immersivecontrolpanel_cw5n1h2txyewy' folder, will this cause permanent damage to my systems or will they still function properly? (I haven't noticed any problems yet)"

I know that Malwarebytes staff isn't Microsoft, but based on the information above and the evidence I can present, do you feel confident in saying that this is a false positive? Admittedly, I do nnot have the ControlPanel.settingcontent-ms file on my computer since Windows Defender deleted it, but I have a link leading to the virus total page whee I uploaded it to the website; as of right now, Virus Total doesn't flag the file in question as malicious across any A.V./A.M.

Thank you for taking the time to read this monster of a post and I hope to hear from you soon!

Based on input from another user, I too would believe this is a FP from Microsoft. I have not scoured the Web or Microsoft site looking for confirmation but since the file contains no bad code and no other scanners found anything either it would  sure seem to be a FP.

 

I did find your post on Microsoft though
