Help! ZeroAccess Rootkit infection

[amnesia91]

Not sure how, probably downloading something I shoudlnt, but I've managed to get stuck with this blighter.

I've run Malwarebytes numerous times, and it says it is removing it, only for it to be there I reboot.

Having done some reading on it, it looks pretty serious and clearly theres no way I'm going to get rid of it on my own, so I'm throwing myself on your mercy!

Any help you provide will be very gratefully received.

DDS and Attach both attached.

I've also taken the liberty of attaching the RogueKiller file.

Thanks in advance

Welcome to the forum >>> Here you go......

Your computer is infected with a nasty rootkit. Please read the following information first.

You're infected with Rootkit.ZeroAccess, a BackDoor Trojan.

BACKDOOR WARNING

------------------------------

One or more of the identified infections is known to use a backdoor.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would advice you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the infection has been identified and because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

When Should I Format, How Should I Reinstall

I will try my best to clean this machine but I can't guarantee that it will be 100% secure afterwards.

Let me know what you decide to do. If you decide to go through with the cleanup, please proceed with the following steps.

-----------------------------------------

Please make sure system restore is running and create a new restore point before continuing!

For x32 (x86) bit systems download Farbar Recovery Scan Tool and save it to a flash drive.

Are you on a wireless network??

MrC

[amnesia91]

Because: a) I'm an idiot and b) didn't read the instructions properly

To answer your question, no I'm not on a wireless network, the laptop is plugged into the router, but it is occasionally used wirelessly.

[MrCharlie]

OK, please remind me that we have to restore those files.

~~~~~~~~~~~~~~~~~~~~~

Please download and run ComboFix.

The most important things to remember when running it is to disable all your malware programs and run Combofix from your desktop.

Please visit this webpage for download links, and instructions for running ComboFix

http://www.bleepingc...to-use-combofix

Ensure you have disabled all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

Information on disabling your malware programs can be found Here.

Make sure you run ComboFix from your desktop.

Give it at least 30-45 minutes to finish if needed.

Please include the C:\ComboFix.txt in your next reply for further review.

---------->NOTE<----------

If you get the message Illegal operation attempted on registry key that has been marked for deletion after you run ComboFix....please reboot the computer, this should resolve the problem. You may have to do this several times if needed.

MrC

[amnesia91]

Ok, we got there in the end, but it was far from straight forward.

CF log attached

Combofix.txt

[MrCharlie]

Looks Good.....

Please Update and run a Quick Scan with MBAM, post the report.

Make sure that everything is checked, and click Remove Selected.

Please let me know how computer is running now, MrC

[amnesia91]

Great thanks.

MBAM log attached

Semms to be running fine - better than it has in a long time, and able to cope with more programs open at once. And no re-direction from Google which is a winner.

mbam-log-2012-09-01 (00-20-01).txt

[MrCharlie]

Great, we have to restore those files that you deleted:

Download TDSSQlook.exe

Run it and choose A scan and press Enter

Copy the log back here TDSSQ.txt

You can find it in C:\TDSSQ.txt

This will start TDSSQlook and replace the file (you won't see anything happening though)

MrC

[amnesia91]

Ok done that - the missing files have appeared on my desktop

[MrCharlie]

OK, that sometimes happens, just delete them. MrC

[amnesia91]

Ok, cool. Done that.

Is that it?

[MrCharlie]

Lets check your computers security before you go:

Download Security Check by screen317 from HERE or HERE.

• Save it to your Desktop.
• Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.
• A Notepad document should open automatically called checkup.txt; please post the contents of that document.

MrC

[amnesia91]

Thats great, thanks.

You have out dated programs on the system which are vulnerable to malware.

Please update or delete them

Info on doing that can be found in my Preventive Maintenance below.

~~~~~~~~~~~~~~~~~~`

A little clean up to do....

Please Uninstall ComboFix: (if you used it)

Press the Windows logo key + R to bring up the "run box"

Copy and paste next command in the field:

ComboFix /uninstall

Make sure there's a space between Combofix and /

Then hit enter.

This will uninstall Combofix, delete its related folders and files, hide file extensions, hide the system/hidden files and clears System Restore cache and create new Restore point

(If that doesn't work.....you can simply rename ComboFix.exe to Uninstall.exe and double click it to complete the uninstall)

---------------------------------

Please download OTL from one of the links below: (you may already have OTL on the system)

http://oldtimer.geekstogo.com/OTL.exe

http://oldtimer.geekstogo.com/OTL.com

http://www.itxassoci...T-Tools/OTL.exe

Save it to your desktop.

Run OTL and hit the CleanUp button. (This will cleanup the tools and logs used including itself)

Any other programs or logs you can manually delete.

IE: RogueKiller.exe, RKreport.txt, RK_Quarantine folder, C:\FRST, etc....
