Avira finds hidden registry entries

Avira finds two hidden registry objects. Can they be possible rootkits? i tried a google search i haven't found anything on them. I also posted in the avira forums, I didn't really get much input about what it can be. They mentioned a software called studio 9 uses hidden registry entries but I never installed this software. What else could it be?

Heres what it finds:

Starting search for hidden objects.
HKEY_LOCAL_MACHINE\Software\Classes\CLSID\{EB763CD6-EB61-CF33-466E-3849D06F
1F61}\InProcServer32\oaklgcffoomoodagbbadblbhlbffjc
[INFO] The registry entry is invisible.

'315899' objects were checked, '2' hidden objects were found.

Re: Avira finds hidden registry entries

Open Regedit and navigate to:

HKEY_LOCAL_MACHINE\Software\Classes\CLSID\{EB763CD6-EB61-CF33-466E-3849D06F1F61}

What DLL or other program is referenced there?

The key is this value: {EB763CD6-EB61-CF33-466E-3849D06F1F61} I do not have a Google hit on it, but that is not definitive of anything.

Look with regedit under the root key above and see if you can find a reference to something that is searchable.

There are no references to this when go to this key. Also trying to open InProcServer32 folder gives me an error - "cannot open InProcServer32: Error while opening key"

Do you use Daemon tools?
I do use daemon tools and i know it uses a type of rootkit technology but can they be related to these key? I have used sophos anti-rootkit scanner before and it leads to this key.: \HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\d347prt\Cfg\0Jf40 which I know is related to daemon tools.

I'm not sure, I just know Daemon Tools shows up in some scanners.

Since there is no reference to a PE type of file, the entry is harmless.

It looks to me to be a lookup table. For example, I might use the registry as a scratchpad to hold configuration settings.

It most assuredly is not a rootkit reference, and most assuredly is not an active threat. There is not there, there. The fact that it is hidden is the only interesting thing about it; but there is nothing particularly interesting about that either. If I was using the registry to record, say GUI settings, I likely would hide it so that all those who love to run registry cleaners did not zap the parameter lookup table storage area.

Without a PE reference, there is no harm and no foul.

Take the CLSID: {EB763CD6-EB61-CF33-466E-3849D06F1F61}
And use that value to search HKLM and HKCU to see if there are additional entries that lead to something intelligible.

Re: Avira finds hidden registry entries

I've searched for that value, there are no other entries that point to anything. I will take your word that its probably not a rootkit and i'm just being a little too paranoid about it. thanks for the help.

What do you mean when you say PE? I'm not familiar with that term in this context.

Re: Avira finds hidden registry entries

PE = "Portable Executable"
»en.wikipedia.org/wiki/Portable_Executable

Sorry for the use of jargon.

if the regkey, supposedly, is "hidden", i don't see how you were able to find it in the registry, unless it is not really hidden.. if it is not really hidden, then why did antivir flag it..

i would do a scan with "GMER" and see if it flags anything..

i also think that you should discuss this issue in the avira forum, so that, if there is a problem with antivir's rootkit-scanner, it is brought to their attention..

Hi redwolfe, I ran a scan with gmer and this is what it found for the registry portion:

---- Registry - GMER 1.0.14 ----

Reg HKLM\SYSTEM\CurrentControlSet\Services\d347prt\Cfg\0Jf40
Reg HKLM\SOFTWARE\Classes\CLSID\{EB763CD6-EB61-CF33-466E-3849D06F1F61}\InProcServer32
Reg HKLM\SOFTWARE\Classes\CLSID\{EB763CD6-EB61-CF33-466E-3849D06F1F61}\InProcServer32@oaklgcffoomoodagbbadblbhlbffjc 0x69 0x61 0x6C 0x65 ...
Reg HKLM\SOFTWARE\Classes\CLSID\{EB763CD6-EB61-CF33-466E-3849D06F1F61}\InProcServer32@naklmdmgnchnoppccdacnndjgjek 0x6A 0x61 0x69 0x65 ...

---- EOF - GMER 1.0.14 ----

So does this mean that avira is correctly flagging this entry and I should still ignore it? thanks

Re: Avira finds hidden registry entries

blaze, here is a link to a forum at "castlecops" where "experts" can help you with analyzing the GMER scan-results:

»www.castlecops.com/f233-Rootkit_···ons.html

alternatively, you could post in DSLReports' "cleanup" forum and see if any of the experts, there, have any suggestions.. here is a link for the forum:
