What is missing startup file? and trojan

I have just run Sysinternals Autoruns on my Windows 11 laptop. Autoruns details things that run at startup.

In the section HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer\ShellExecuteHooks
it shows a missing file
{3CF9ECE0-1A9F-11d2-8C73-00C06C2005DE} File not found:

I have googled this string of characters and found relates to Directory Opus.

It doesn't give the name of the missing file, What exactly is missing?
Do I need to do anything about it?
DOpus seems to working ok, so I'm not sure what it refers to.

More worryingly, my searching led me to a site called Dr Web which says Directory Opus contains Trojan.Siggen28.57960

Here is link to the web site.. Trojan.Siggen28.57960 — Dr.Web Malware description library

DOpus has been around for a long time, why are they saying it contains a trojan?

Have a look

Toggling Preferences / Launching Opus / Explorer Replacement might be all you need to do.

Sounds like a bug in autoruns. It’s a CLSID not a file path.

Utter nonsense, unless they’re talking about a pirate version or something, which could contain anything.

Thanks for the replies, I don't have a crash and no problem with Dopus, it runs great. Maybe the missing item (CLSID) shown by Autoruns is because I have set DOpus not to start with Windows 11 and not to replace Windows File Explorer.

Either way, it doesn't cause any issues, I just wondered why Autoruns said it was missing, which made me think it should not be. I'm someone who tries to find an explanation for everything :slight_smile:

Regarding the drweb site which details various Dopus files as trojan. I agree, they're talking nonsense, they should get facts right and not post misinformation about highly regarded reputable software.
