Welcome to the forum.

Please remove any usb or external drives from the computer before you run this scan!

Please download and run RogueKiller to your desktop.

For Windows XP, double-click to start.
For Vista or Windows 7, do a right-click on the program, select Run as Administrator to start, & when prompted Allow to run.


Click Scan to scan the system.
When the scan completes > Close out the program > Don't Fix anything!

Don't run any other options, they're not all bad!!!!!!!

Post back the report which should be located on your desktop.

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:

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 Files tab
Put a check next to all of these and uncheck the rest:

¤¤¤ Particular Files / Folders: ¤¤¤
[ZeroAccess][FILE] @ : c:\windows\installer\{37d014df-7cdb-0ce1-c8d4-6ff1206dddc8}\@ --> FOUND
[ZeroAccess][FOLDER] U : c:\windows\installer\{37d014df-7cdb-0ce1-c8d4-6ff1206dddc8}\U --> FOUND
[ZeroAccess][FOLDER] L : c:\windows\installer\{37d014df-7cdb-0ce1-c8d4-6ff1206dddc8}\L --> FOUND
[ZeroAccess][FILE] @ : c:\documents and settings\rob\local settings\application data\{37d014df-7cdb-0ce1-c8d4-6ff1206dddc8}\@ --> FOUND
[ZeroAccess][FOLDER] U : c:\documents and settings\rob\local settings\application data\{37d014df-7cdb-0ce1-c8d4-6ff1206dddc8}\U --> FOUND
[ZeroAccess][FOLDER] L : c:\documents and settings\rob\local settings\application data\{37d014df-7cdb-0ce1-c8d4-6ff1206dddc8}\L --> FOUND


Now click Delete on the right hand column under Options

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

Then.......

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.

No, you're "good to go"......just >

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 /

Posted Image

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

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, etc....

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

Any questions...please post back.

If you think I've helped you, please leave a comment > click on my avatar picture > click Profile Feed.

Take a look at My Preventive Maintenance to avoid being infected again.

Good Luck and Thanks for using the forum, MrC
