Infected with Trojan.0Access - Please help

[ag97]

My nephew was using my PC and seems that he was visiting malicious websites because now I see multiple security alerts from Avira and also Malwarebytes is reporting multiple files in C:\$RECYCLE.BIN folder moved to quarantine and all of them are identified as "Trojan.0Access". I have dedicated some time looking for a fix on the Internet and found similar issues reported in this forum. I was tempted to follow the solutions but I know each case could be different so I want to report my case and hopefully get the assistance I need to completely resolve this issue.

[MrCharlie]

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:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

http://www.dslreports.com/faq/10451

When Should I Format, How Should I Reinstall

http://www.dslreports.com/faq/10063

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.

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

Run RogueKiller again and click Scan

When the scan completes > click on the Registry tab

Put a check next to all of these and uncheck the rest: (if found)

[HJ INPROC][ZeroAccess] HKCR\[...]\InprocServer32 : (C:\$RECYCLE.BIN\S-1-5-18\$c4b4519eacc82a67a5db9d694f28ccd9\n) [-] -> FOUND

Now click Delete on the right hand column under Options

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

Next click on the Files tab and put a check next to these and uncheck the rest. (if found)

[ZeroAccess][FILE] n : C:\$recycle.bin\S-1-5-18\$c4b4519eacc82a67a5db9d694f28ccd9\n [-] --> FOUND

I followed your instructions and please find attached the TDDSKiller log as requested.

[MrCharlie]

Well Done, lets run ComboFix to clear up any leftovers.

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.bleepingcomputer.com/combofix/how-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.

[ag97]

Please find attached ComboFix.txt.

Good......

Lets check your computers security before you go and we have a little cleanup to do also:

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.
  
• Do Not Attach It!!!
  

MrC

[ag97]

I noiced the P2P was disabled when running the scan so I did it one more time making sure everything is checked as indicated and the result is again a clean log.

Here is checkup.txt

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

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

Please update or uninstall them

Info on doing that can be found in my Preventive Maintenance

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

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, MBAR, etc....AdwCleaner > just run the program and click uninstall.

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

Any questions...please post back.
