Hey, new here and was hoping someone could help me. I have the RootKit.0Access problem. I tried to follow the instructions you laid out here, but I got really REALLY lost. It's been almost 10 years since I've had any virus or malware. In that time I've lost a lot of computer skills, so I really need someone to help me step by step. Thanks to anyone who is willing to try!

[planex]

P.S. I would have attached DDS and Attach, but I don't know what those are.

[MrCharlie]

Welcome to the forum, please start at the link below:

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.

I have the files for you. I feel stupid saying this, but I don't know how to attach them.

[planex]

Nevermind, I found it under "more options." Here you go. Thanks for your help!

Oh! I doubt it's worth mentioning, but during those scans Malwarebytes was scanning. I doubt it interfered with anything. Also, when RogueKiller finished scanning it linked me to this site. My guess it that I won't be using any of the information on that site. Thanks!

[MrCharlie]

Here you go......

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

Quote

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
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.

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

Before we proceed further, please uninstall or disable uTorrent and any other peer-to-peer filesharing app.
Continued use of filesharing or ill-advised downloads will surely re-infect your system.

Here are the files you asked for. I don't mean to sound ungrateful, but torrents can be used for legitimate purposes too. I take some offense to the view that torrenting is always an aid to piracy. I am not a pirate and do not participate in illegal activities.

By the way, what do I do with the contents of C:\Users\User\Desktop\RK_Quarantine? Just so we're clear, I disabled uTorrent, but I don't agree with the view that having such a program installed labels me as some sort of criminal.

[MrCharlie]

First of all it's not my policy > I have nothing to do with Malwarebytes and I'm not one of the staff.
I just follow the forums rules just like you have to!

Like it says in my signature: I volunteer my free time to help you.

Here's the stated policy on P2P programs:

Quote

If you're using Peer 2 Peer software such as uTorrent or similar you must either fully uninstall it or completely disable it from running while being assisted here.
Failure to remove or disable such software will result in your topic being closed and no further assistance being provided.

The reason they want it disabled is:

Continued use of filesharing or ill-advised downloads will surely re-infect your system.

Not piracy.

By the way, what do I do with the contents of C:\Users\User\Desktop\RK_Quarantine?

Leave it for now, when we are done you can delete it.

That's not what they're saying...again the resaon is:

You have to take it up with the forums administration .....OK!!

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

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)

I ran RogueKiller again like you said. I deleted the first two but the following said it was replaced instead of being deleted: [HJ INPROC][ZeroAccess] HKCR\[...]\InprocServer32 : (C:\$Recycle.Bin\S-1-5-21-297971519-1915049780-1549598355-1001\$3568e537840c333f469ff821fd809671\n.) -> FOUND

I appreciate that you're giving your time to do this for free. I meant no disrespect.

I am now about to start the next part of the process and run FRST64 from System Recovery.

[planex]

I'm still getting redirects. Trying to log in to the forums here I was redirected to some mal site. I don't know if that's unusual for this stage of the process or not. I have attached the file you requested. Just as I was typing this Malwarebytes gave me a pop-up. I took a screenshot and attached it. Again, not sure if that's unusual for this stage. Again, thank you for your continuing support.

I am on a network with my roommate (who is very good with computers and very security conscious). I am hardwired into the network, but we do have password protected wireless access.

While I'm thinking of it, would using a restore point from a few weeks ago solve this whole problem?

I am now beginning the process with TDSSKiller.

[planex]

Ok, here is the log and the end screen for TDSSKiller. Just for additional information, there was a checkbox that said "Scan Loaded Modules." I left it unchecked because I wasn't sure.

No

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

The TDSSKiller log is clean, those files are good.

Can you hook up directly to the modem and by pass the wireless?

If so........

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

[planex]

Ok, about to run Combofix following the instructions in the link. I will have to leave for work in less than an hour. I'm hoping combo fix will be done by then. If not, I'll have to leave it running and come back to it - and this post - when I return home.

[planex]

Oh, I am always directly connected (via Ethernet cable). I do not ever connect to my network via wireless.

[MrCharlie]

OK, let me know.....MrC

[planex]

Here is the log from ComboFix. I would like to note that after running it and resarting several times, my computer is unable to see any networks whatsoever. I was only able to get online by borrowing my roommate's laptop. I've tried the few basic things I know to reestablish connection, but it literally thinks there's nothing there. I don't know how ComboFix works so I can't say what it did. I could sure use some help reestablishing my network connection.

Time for me to head out the door. I'll check back in 6 to 10 hours. Thanks for your help thus far. Please don't ghost on me!
