Possible rootkit infection?
« on: March 18, 2015, 07:32:55 AM »
Hi

My system was detecting some strange virus etc at random interval .. like for instance last detection was like 1/2 hour earlier and the one before that was 5/6days ago and when it happens ... avast keeps detecting this/that(mentioned bellow) for a brief period of time ... I'm using avast free version(latest update). All previous detections(some were detected multiple times):

C:\Users\Public\Favouries\Favourites.bat [Infection= Win32:RmnDrp]
C:\Users\Public\Libraries\Libraries.pif [Infection= Win32:RmnDrp]
C:\Users\Public\Pictures\Pictures.exe [Infection= Win32:RmnDrp]
C:\Users\Public\Pictures\NVIDIA Corporation\Corporation.bat [Infection= Win32:RmnDrp]
C:\Users\Public\Pictures\NVIDIA Corporation\3D Vision Experience\Vision Experience.exe [Infection= Win32:RmnDrp]
C:\Users\Public\Pictures\NVIDIA Corporation\3D Vision Experience\3D Vision Preview Pack 1\3D Vision Preview Pack 1.bat [Infection= Win32:RmnDrp]
C:\Users\Public\Pictures\Recorded TV\Recorded TV.exe [Infection= Win32:RmnDrp]
C:\Users\Public\Pictures\Recorded TV\Temp Rec\Temp Rec.exe [Infection= Win32:RmnDrp]
C:\Users\Public\Pictures\Recorded TV\Temp Rec\TemSBE.bat [Infection= Win32:RmnDrp]
C:\Users\Public\Pictures\Recorded TV\Temp Rec\Sample Media\Media.bat [Infection= Win32:RmnDrp]
C:\user\public\documents\DELL.exe [Infection= Win32:KillAV-AJZ[TRJ]
C:\user\public\documents\documents.exe [Infection= Win32:RmnDrp]
C:\user\public\documents\downloads\downloads.exe [Infection= Win32:KillAV-AJZ[TRJ]
C:\users\public\public.exe [Infection= Win32:KillAV-AJZ[TRJ]
C:\users\public\documents\dell\musicstage\MusicStage.scr [Infection= Win32:RmnDrp]
C:\users\public\Music\Music.scr [Infection= Win32:GenMalicious-BJV[Trj]

Then I scaned with avast+malewarebytes+supertin+rkill+ProcessExplorer+AdwCleaner+BootkitRemoval(bit defender)+MBAR(malewarebytes anti rootkit)+tdsskiller+ UKV(ultra kirus killer ... and all results the same ... nothing found.

Well so like 5days ago when detections stopped, I thought(hopped) that its gone somehow(stupid iknow) but anyway .. today avast detected again ... and I'm not getting this at all .. I mean the mentioned AV/Security tools above are quite good but they all fail at this .. and even Avast can't seem to detect the cause of this ..

I'm no expert on this but from my understanding .. something keeps recreating(at random interval) the files that avast detects .. and its possibly still in my system (hiding somewhere) .... or someone suggested .. it could be something like a drive by virus/something similar.

Whatever it maybe .. its getting into my system passing all security measures .. usually I have avast+malewarebytes+windwos defender active .. and as mentioned previously .. avast can detect everything(I think) that this specific virus creates .. however it or none of the mentioned security tools can detect the "Root" of this issue.

Any help is much appreciated.

if avast is correct, it seems you have a fileinfector ....
this is often bad news, depending on how far it has spread or avast is able to hold it back, this oftens end with a format C / reinstall

see blog here by Miekiemoes - Director of Research @ Malwarebytes   http://miekiemoes.blogspot.no/2009/02/virut-and-other-file-infectors-throwing.html

good or bad news, you find out when essexboy check your logs

Oh man .. I was actually hoping to avoid something like this ...

Lets hope for the best .. because I really don't want to use system recovery disk as it was created when I purchased this laptop .. about 3years ago ...

Anyway scan logs attached

I don't see much changes really .. performance wise.
About avast detection ... it used to happen randomly, as I have mentioned in my first post ... last detection was yesterday and the one before that 5/6days ago ... I suppose we'll have to wait and see(will keep you guys posted).
BTW do you have any suggestions on how do we recreate the event(avast detection) as in make the virus active? .. I really would like to have this thing removed for good.

I have one question though ... I have probably not the best security setup but decent setup or atleast I would like to think so .. my question is: how did thing virus or whatever it is .. get through?

As they are in the public folders then I would assume it is to do with a website you have
You can scan the folder with Avast and see if they are still there

Usually when they are auto generated ... avast detects them., right now no detections.

About the website part ... Just wondering ..how is it that avast can detect whatever the website creates within public directory and yet not the "root" of the problem itself(the script that keeps recreating those files at random interval)?

Also as I don't know which site is causing this issue(if infact it is), how do I prevent this from happening again? any suggestions?

Might be worth checking the individual website with zuluscaler http://zulu.zscaler.com/ to see if it can detect anything.  By web site I mean ones that you control and update

The public folders are where you put stuff that is shared between computers and websites.  I you manage/own/ control a web site that is where you would put stuff
