suspect rootkit or other virus

I recently discovered that my windows update is not working and neither is my firewall. I looked around and discovered that a possible cause could be a rootkit. I have very little experience dealing with this type of infection and would appreciate any help.

I have attached the reccomended logs.

heres part 2 of the otl log

Hi you have an old copy of OTL could you delete it from your desktop please

Download and Install Combofix

Download ComboFix from one of the following locations:
Link 1
Link 2

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

[*]Double click on ComboFix.exe & follow the prompts.
[*]Accept the disclaimer and allow to update if it asks

[*]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.
  3. If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.

Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

THEN

Download OTL 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
BASESERVICES
%SYSTEMDRIVE%*.exe
/md5start
services.*
explorer.exe
winlogon.exe
Userinit.exe
svchost.exe

%systemdrive%$Recycle.Bin|@;true;true;true
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

Unfortunately Combofix would not run properly. it got all the way through updating and then left me the message that it would only run on windows 2000 or XP. I am running 7 home premium and my PC is 64 bit. Should I just move on to OTL? As for my computer it actually seems to be running normally. The only problems i am having is that windows update and the firewall are not working properly and windows was unable to do anything to fix the problem.

Yes run the new copy of OTL as that will show me the services and any associated problems

I ran OTL as directed. Extras .txt did not appear and it could not be found on my desktop where OTL is or in my docs folder or downloads… Here is OTL.txt though

OK lets do some repair work first and the revisit the Combofix failure on completion

Download Windows Repair (all in one) from this site

Install the programme then run

Go to step 3 and allow it to run SFC

https://dl.dropbox.com/u/73555776/waio%20step3.JPG

On the start repairs tab click start

https://dl.dropbox.com/u/73555776/waiostart%20rep.JPG

Select the following items and tick restart system when finished

https://dl.dropbox.com/u/73555776/waio%20rep%20list.JPG

okay, program run as directed. The firewall seems to have kicked in. I haven’t checked windows update. What do you need me to do next?

OK lets check the rest of the services now… What are the current problems ?

run farbar service scanner

https://dl.dropbox.com/u/73555776/FSS.GIF

Tick “All” options.
Press “Scan”.
It will create a log (FSS.txt) in the same directory the tool is run.

Please copy and paste the log to your reply.

Actually, both the firewall and the update seem to be working. So no problems are apparent. I think we’re done unless you think it’s a good idea to run other programs. I ran that program anyways though. here is the log.

I could see no sign of a rootkit, if you are happy I will remove my tools

I am. Thank you very much, for your help. Hope you have a nice day.

Subject to no further problems :slight_smile:

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems

Now the best part of the day ----- Your log now appears clean :thumbsup:

A good workman always cleans up after himself so…The following will implement some cleanup procedures as well as reset System Restore points:

Run OTL
[*]Under the Custom Scans/Fixes box at the bottom, paste in the following

:Commands [resethosts] [emptytemp] [Reboot]

[*]Then click the Run Fix button at the top
[*]Let the program run unhindered, reboot the PC when it is done

Remove ComboFix

[*]Hold down the Windows key + R on your keyboard. This will display the Run dialogue box
[*]In the Run box, type in ComboFix /Uninstall (Notice the space between the “x” and “/”) then click OK

http://i1224.photobucket.com/albums/ee362/Essexboy3/Misc%20screen%20shots/CF_Uninstall-1.jpg

[]Follow the prompts on the screen
[
]A message should appear confirming that ComboFix was uninstalled

Run OTL and hit the cleanup button. It will remove all the programmes we have used plus itself.

We will now confirm that your hidden files are set to that, as some of the tools I use will change that

[*]Go to control panel
[*]Select folder options (Appearance > Folder options in category view)
[*]Select the View Tab.
[*]Under the Hidden files and folders heading select Do not show hidden files and folders.
[]Click Yes to confirm.
[
]Click OK.

SPRING CLEAN

To manually create a new Restore Point

[*]Go to Control Panel and select System
[*]Select System
[*]On the left select System Protection and accept the warning if you get one
[*]Select System Protection Tab
[*]Select Create at the bottom
[*]Type in a name i.e. Clean
[*]Select Create

Now we can purge the infected ones

[*]GoStart > All programs > Accessories > system tools
[*]Right click Disc cleanup and select run as administrator
[*]Select Your main drive and accept the warning if you get one
[*]For a few moments the system will make some calculations
[*]Select the More Options tab
[*]In the System Restore and Shadow Backups select Clean up
[*]Select Delete on the pop up
[]Select OK
[
]Select Delete

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

http://img233.imageshack.us/img233/7729/mbamicontw5.gif

Malwarebytes. Update and run weekly to keep your system clean

Download and install FileHippo update checker and run it monthly it will show you which programmes on your system need updating and give a download link

It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit

[*]Microsoft Windows Update
