Title: New Virus?
Post by: RoughDobermann on September 24, 2011, 01:56:57 AM
Hi All:

According to Avast, my work laptop is infected by a "rootkit" named:

1264341053:3266290612.exe

c:windows/1264341053:3266290612.exe

I take the prescribed action (Delete) and schedule a boot scan (as suggested) and the little bugger is right back.  Nasty stuff.

Any ideas?

This needs further analysis by a malware removal specialist:
Go to this topic http://forum.avast.com/index.php?topic=53253.0 (http://forum.avast.com/index.php?topic=53253.0) for information on Logs to assist in cleaning malware. Use the information about getting and using the logs and start your own new topic and attach the logs there, not in the LOGS topic.

It is almost 1:20am in the UK and it is likely to be tomorrow morning when a malware removal specialist can take a look at it. So if you can get on with the process and that will give them something when they do get on-line.

Thanks, but here's a problem:  This bug apparently won't let me run Malwarebyte's AntiMalware.  The Quick Scan runs for a few seconds and then the program closes.  If I try again, a warning comes up that says something like "Program can't be found."  If I re-install MBAM, it runs again just like before.  Same thing with HiJack This.

Hi that is the zero access bootkit.  I will first need to remove the ads from the bad boy and then run to kill

 Download OTL (http://oldtimer.geekstogo.com/OTL.exe)  to your Desktop
netsvcs
%SYSTEMDRIVE%\*.exe
/md5start
explorer.exe
winlogon.exe
Userinit.exe
svchost.exe

 Download OTL (http://oldtimer.geekstogo.com/OTL.exe)  to your Desktop
  • Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.
  • Select All Users
  • Under the Custom Scan box paste this in
netsvcs
%SYSTEMDRIVE%\*.exe
/md5start
explorer.exe
winlogon.exe
Userinit.exe
svchost.exe
/md5stop
C:\Windows\assembly\tmp\U /s
CREATERESTOREPOINT

  • Click the Quick Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
    • When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
    • Post both logs

Thanks!  I'm doing the scan now.  A Microsoft Error Reporting box came up during the scan.  It looks a little different than a "normal" MS error report.  Normal?

OK here we go

Warning This fix is only relevant for this system and no other, using on another computer may cause problems

Run OTL
THEN

When you download the following programme you must save it to your desktop renamed as svchost

Download and Install Combofix
 
Download ComboFix from one of the following locations:
Link 1  (http://download.bleepingcomputer.com/sUBs/ComboFix.exe)
Link 2 (http://www.forospyware.com/sUBs/ComboFix.exe)
 
VERY IMPORTANT !!! Save ComboFix.exe to your Desktop
 
* IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here  (http://"http://forums.whatthetech.com/How_Disable_your_Security_Programs_t96260.html&pid=494216#entry494216")
As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
 

**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.

When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply.
Notes:
1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. Do not "re-run" Combofix. If you have a problem, reply back for further instructions.
 
Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

In my eagerness to fix this (leave tomorrow for a week business trip), I followed the advice of a "friend" who had me run TDSSKiller.exe.  It apparently found the bug (I have sound again) and no longer have the problem I mentioned in the first post, but I have neither wired not WiFi internet (limited/no connection).

Sorry.

Should I still do what you mention above or do another OTL scan?
Title: Re: New Virus?
Post by: essexboy on September 24, 2011, 10:33:20 PM
The problem with TDSKiller is that it does not see the mwsock infection as well

Run the OTL fix followed by combofix and that may re-instate the connection - if not I will look at manually fixing it

Okay, will do.  But, since I don't have access to the Interwebs on the laptop (but do on this PC), can I just download Combofix onto a thumb drive and place it on the laptops desktop (per instructions).  And, what if when I run Combofix and it has to get on the Internet to download the Windows Recovery thing?

Look for a yellow exclamation mark

Is there one next to the network adapter ?

If so select the ethernet one (Yukon)
Right click and select uninstall
Reboot and windows will reload the driver for that

Does the ethernet now work

It's asking me to uninstall Symantec through Add/Remove.  That is asking for a password I don't have.

I checked to see if DHCP client would start.  It won't.  Same error as before.

Could you go to this page http://support.microsoft.com/kb/915162

It will ask you to enter the registry this is a brief synopsis - what I would like to know is, are there any additional entries apart from the three mentioned ?

1.Click Start, click Run, type regedit in the Open box, and then click OK.
2.In Registry Editor, locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dhcp

3.Right-click the DependOnService entry, and then click Modify.

4. In the Value data box, delete the service that is described in the event that appears in the "Symptoms" section.
 
Note Typically, the only services that are in the DependOnService entry are the following services:

■Tcpip
■Afd
■NetBt

5. Close Registry Editor, and then restart the computer.

No, there are just those three entries, but NetBt is listed as "NetBT" not "NetBt"
Title: Re: New Virus?
Post by: RoughDobermann on September 27, 2011, 02:36:13 PM
Not sure if this matters, but the first entry (default) is (value not set)

I wonder if this a permissions problem as that is one of the zero access symptoms

Download this tool from here and install http://www.tweaking.com/content/page/windows_repair_all_in_one.html

Start the programme and go through steps one to four, or if time is short then select start repairs
Select the advanced option
Place a tick in reset registry permissions only
Then click start - reboot on completion

Okay did that.  Still no internet
Title: Re: New Virus?
Post by: essexboy on September 27, 2011, 05:09:30 PM
OK this does not appear to make any sense so I will do some deeper research
Title: Re: New Virus?
Post by: RoughDobermann on September 27, 2011, 05:12:05 PM
Under the Dependencies tab in DHCP Client Properties,  I now have:

AFD
TCP/IP Protocol Driver

But no NetBT
Title: Re: New Virus?
Post by: essexboy on September 27, 2011, 05:18:00 PM

Could you type the following in the run box pleae and let me know what the output is

CMD /K SC QC DHCP

It should be this

There is no data listed under DependOnGroup.  No idea if that is helpful!
Title: Re: New Virus?
Post by: RoughDobermann on September 27, 2011, 05:21:46 PM
Yes mine is the same
Title: Re: New Virus?
Post by: essexboy on September 27, 2011, 05:38:38 PM
Darn this is where I could do with an XP machine so that I could export that set of registry entries for you

Now  do the following

Click Start, Run and type DEVMGMT.MSC
In the View menu, click Show hidden devices
Double-click Non-Plug and Play drivers section
Double-click the entry AFD, and click the Driver tab
Set the Startup type to System.
Start the service. Note down the error message if any.
Similarly start the two other drivers namely:
TCP/IP Protocol Driver
NetBios over Tcpip

Close Device Manager and restart Windows.

Then run Regedit via the run key

Navigate to HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Dhcp
Right click the DependOnService select modify (shot 1)
Ensure that in the box that shows that you have the following entries (or add them) (shot 2 )

Post by: RoughDobermann on September 27, 2011, 05:46:39 PM
Afd and tcip both started.  There is no entry for netbios under dm, nonplugandplay!  It's not there!

Is the registry entry the one in your post if so I will export mine (XP Pro SP3) ?

See image extract of the key on my system.

I looked for netbt.sys under windows/system32/drivers and it IS there.  Shod I go to another xp machine copy it's netbt file and put it on mine?  There's a win 7 mChine downstairs
Title: Re: New Virus?
Post by: RoughDobermann on September 27, 2011, 05:57:31 PM
Yes mine looks identical
Title: Re: New Virus?
Post by: essexboy on September 27, 2011, 05:59:23 PM
Aye the file is there and it is a good copy, that was the one I replaced earlier

Go to control panel
Open the Network Connections folder.
Right click the local area network connection and click Properties.
Double click Internet Protocol (TCP/IP).
Click Advanced.
Click WINS.
Click the Enable NetBIOS Over TCP/IP button.

Post by: RoughDobermann on September 27, 2011, 06:09:59 PM
Ok enabled netbios on both LAN and wireless connections.  Rebooted and no Internet.  Netbt not shown under dependencies
Title: Re: New Virus?
Post by: DavidR on September 27, 2011, 06:11:26 PM
@ essexboy
I have that enabled, part of the default setting, see image and works fine on my system.
Title: Re: New Virus?
Post by: essexboy on September 27, 2011, 07:33:33 PM
OK back into the registry to ensure that the path is set correctly

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\NetBT
check that the image path is set at system32\drivers\netbt.sys

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\NetBIOS]
check that the image path is set at system32\drivers\netbios.sys
Title: Re: New Virus?
Post by: RoughDobermann on September 27, 2011, 08:53:08 PM
That worked, mostly!   Netbios still seems funny.  Dns works but not for wins resolution? 
Title: Re: New Virus?
Post by: essexboy on September 27, 2011, 08:58:55 PM
Sheesh well that took some following to find a partial resolution

OK what appears to be the current problem ?
Title: Re: New Virus?
Post by: RoughDobermann on September 28, 2011, 05:49:23 AM
My IT guy followed your advice and saw that the registry entry for NetBios (?) was COMPLETELY empty.  He did something and I am now fully operational again!  I cannot thank you enough, essexboy!

Enjoy your holiday!
