ZeroAccess RootKit Infection

[w3junky]

Thanks. I will try these tonight after work. It appears everything is removed though and WIndows Defender is just corrupt and needs to be reinstalled, so I was thinking that is all we need to do now. But of course getting Windows Defender reinstalled is another story.

[D-FRED-BROWN]

Yeah I'd say we should just leave fixing Windows Defender until the end

[w3junky]

So the ESET scan might take all night! But I will attach some of the other logs that I have completed. By the way, the ESET scanner is telling me 6 infected files so far after around 47% done (1 1/2 hrs). I'll attach the files now along with a screen shot of the virus ESET found. I'll update that log once it's done.

Sounds good. Keep me posted .

[w3junky]

ESET finished up. Logs attached.

[D-FRED-BROWN]

Still have a little more to do, but we're nearly there.

----------Step 1----------------
We need to run an OTL Fix

• Please reopen on your desktop.
• Copy and Paste the following code into the textbox.

• Push
• OTL may ask to reboot the machine. Please do so if asked.
• Click the OK button.
• A report will open. Copy and Paste that report in your next reply.

 

----------Step 2----------------

Please download Junkware Removal Tool to your desktop.

• Shut down your protection software now to avoid potential conflicts.
• Run the tool by double-clicking it. If you are using Windows Vista, 7, or 8; instead of double-clicking, right-mouse click JRT.exe and select "Run as Administrator".
• The tool will open start scanning your system.
• Please be patient as this can take a while to complete depending on your system's specifications.
• On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
• Post the contents of JRT.txt into your next message.

 

----------Step 3----------------
Instructions for DELETE:

• Close all open programs and internet browsers.
• Double click on adwcleaner.exe to run the tool.
• Click on Delete.
• Confirm each time with Ok.
• You will be prompted to restart your computer. A text file will open after the restart.
• Please post the contents of that logfile with your next reply.
• You can find the logfile at C:\AdwCleaner[s1].txt as well.

Afterwards, please reboot the computer.

----------Step 4----------------
Please post the OTL and Junkware Removal Tool and AdwCleaner reports in your next reply. How are things running now?

[w3junky]

So after doing Step 1, my PC is sitting at Logging Off for the past 5 mins. Is it ok to do a hard reboot? Things have been running fine since before the latest post, just the Windows Defender issue, so I wasn't sure if anymore malware removals really needed to be done.

[D-FRED-BROWN]

Hmm. If it doesn't finish logging off, try doing a force reboot, then running the script again in Safe Mode.

[w3junky]

The Step 1 seemed to work after a force reboot. I'll attach all logs.

JRT.txt

OTLLog.txt

AdwCleanerS1.txt

[D-FRED-BROWN]

Things look good. Judging by your last few logs, I'd say your system is clean.

Before we move on, please take the time to install the following updates. Program updates are a critical part of your computer's safety net, as outdated applications leave you vulnerable to malware.

 

---------

You're using an old version of Adobe Acrobat Reader, this can leave your PC open to vulnerabilities, you can update it here (uninstall version 7.0 first):
Adobe Reader X

Note: I suggest you uncheck an optional, third-party download (eg. McAfee Security Scan Plus).

After successfully installing Adobe Reader X, see this article on how to make this program more secure: Adobe Reader X secures itself by playing in the sandbox.

 

---------

 

See if you can reinstall Windows Defender- downloading Microsoft Security Essentials will include Windows Defender by default. If you don't wish to use MSE as your active antivirus program, you can always leave it disabled from active mode. http://windows.microsoft.com/en-us/windows/security-essentials-download

 

---------

 

Please let me know how the updates went, as failed updates may be due to malware.

[w3junky]

Thanks. I actually have Adobe X already. Well aware of previous Adobe issues (network engineer for my day job). I do have Adobe Photoshop 7, so maybe that is what you saw. I did follow the steps though to secure Adobe X, so thanks. I will try installing MSE tonight and see how it goes. I really appreciate your time on all of this.

[D-FRED-BROWN]

Sounds good. Keep me posted as to how it goes.

[w3junky]

I was able to just copy the files for Windows Defender from my work PC to my home PC and it seems to be working. So I believe we are done and I totally appreciate your help on this problem. I'll be donating some cash (not nearly as much as you deserve but just a small amount to say thanks).

[D-FRED-BROWN]

Glad to hear the updates went successfully!

Unless there are any other issues, I will now provide you with some steps to better protect your computer.

First, we need to remove ComboFix.

The following will implement some cleanup procedures as well as reset System Restore points:

Click Start > Run and copy/paste the following bolded text into the Run box and click OK:

ComboFix /Uninstall

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

Let's remove OTL and the other tools we used as well:

• Reopen on your desktop.
• Click on
• You will be prompted to reboot your system. Please do so.
  

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

Please consider using these ideas to help secure your computer. While there is no way to guarantee safety when you use a computer, these steps will make it much less likely that you will need to endure another infection. While we really like to help people, we would rather help you protect yourself so that you won't need that help in the future.

Please either enable Automatic Updates under Start -> Control Panel -> Automatic Updates or get into the habit of checking Windows Update regularly. They usually have security updates every month. You can set Windows to notify you of Updates so that you can choose, but only do this if you believe you are able to understand which ones are needed. This is a crucial security measure.

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

It is really dangerous to go online without an antivirus. Without one, you are extremely likely to get infected and the consequences could be even worse next time. All of the following are excellent free antiviruses. Be sure to only install one.

avast!.
AntiVir
AVG
Microsoft Security Essentials

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

Please consider installing and running some of the following programs; they are either free or have free versions of commercial programs:

Spybot-Search & Destroy
A tutorial on using Spybot to remove spyware from your computer may be found here. Please also remember to enable Spybot's "Immunize" and "TeaTimer" features if you don't have the resident part of another anti-spyware program running.

SpywareBlaster
A tutorial on using SpywareBlaster to prevent malware from ever installing on your computer may be found here.

SpywareGuard
A tutorial on using SpywareGuard for real-time protection against spyware and hijackers may be found here.

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

Please, consider maintaining a firewall with HIPS (Host Intrusion Prevention Systems). Firewalls are extremely important and are the first part of your computer's defense. HIPS stops malware by monitoring its behavior and it's very important, too.
A firewall is a software program or piece of hardware that helps screen out hackers, viruses, and worms that try to reach your computer over the Internet.
If you are using the Windows Firewall please note that it doesn't monitor or block outbound traffic and is therefore less effective than other free alternatives.

These firewalls are good and do have free versions available

• Outpost Firewall Free
  Online Armor Firewall
  

A tutorial on understanding and using firewalls may be found here.

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

Please keep your security programs up-to-date and run them whenever you suspect a problem to prevent malware problems. A number of programs have resident protection and it is a good idea to run the resident protection of one of each type of program to maintain protection. However, it is important to run only one resident program of each type since they can conflict and become less effective. That means only one antivirus, firewall and scanning anti-spyware program at a time.

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

Note that there are a lot of rogue programs out there that want to scare you into giving them your money and some malware actually claims to be security programs. If you get a popup for a security program that you did not install yourself, do NOT click on it and ask for help immediately. It is very important to run an antivirus and firewall, but you can't always rely on reviews and ads for information. Ask in a security forum that you trust if you are not sure. If you are unsure and looking for anti-spyware programs, you can find out if it is a rogue here:

http://www.spywarewa...nti-spyware.htm

A similar category of programs is now called "scareware." Scareware programs are active infections that will pop-up on your computer and tell you that you are infected. If you look closely, it will usually have a name that looks like it might be legitimate, but it is NOT one of the programs you installed. It tells you to click and install it right away. If you click on any part of it, including the 'X' to close it, you may actually help it infect your computer further. Keeping protection updated and running resident protection can help prevent these infections. If it happens anyway, get offline as quickly as you can. Pull the internet connection cable or shut down the computer if you have to. Contact someone to help by using another computer if possible. These programs are also sometimes called 'rogues', but they are different than the older version of rogues mentioned above.

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

Please consider using an alternate browser. Mozilla's Firefox browser is a very good alternative. In addition to being generally more secure than Internet Explorer, it has a very good built-in popup blocker and add-ons, like NoScripts, can make it even more secure. Opera is another good option.
If you are interested, Firefox may be downloaded from here
Opera is available here: http://www.opera.com/download/

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

For more useful information, please also read Tony Klein's excellent article: How did I get infected in the first place

Hopefully these steps will help to keep you error free. If you run into more difficulty, we will certainly do what we can to help.

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

I would grateful if you could reply to this post so that I know you have read it and, if you have no other questions, the thread can then be closed.

I will leave the thread open for a few more days. If you need anything, just come back here and let me know. After that time you will have to send me a PM.

Bad news. After doing the final steps in your latest post, after a reboot, the system is unable to load and goes into system recovery and when I attempt to have the system do an auto fix, it fails and tells me "Corrupt Registry". Unable to boot into safe mode as this comes up right away again. I am also unable to do any sort of system restore as I do not have that turned on. Ideas?

[D-FRED-BROWN]

Hmm. I think a system file was deleted. Let's take a look as to what's going on:

 

For x32 (x86) bit systems download Farbar Recovery Scan Tool and save it to a flash drive.
For x64 bit systems download Farbar Recovery Scan Tool x64 and save it to a flash drive.

Plug the flashdrive into the infected PC.

Enter System Recovery Options.

To enter System Recovery Options from the Advanced Boot Options:

• Restart the computer.
• As soon as the BIOS is loaded begin tapping the F8 key until Advanced Boot Options appears.
• Use the arrow keys to select the Repair your computer menu item.
• Select English as the keyboard language settings, and then click Next.
• Select the operating system you want to repair, and then click Next.
• Select your user account an click Next.

To enter System Recovery Options by using Windows installation disc:

• Insert the installation disc.
• Restart your computer.
• If prompted, press any key to start Windows from the installation disc. If your computer is not configured to start from a CD or DVD, check your BIOS settings.
• Click Repair your computer.
• Select English as the keyboard language settings, and then click Next.
• Select the operating system you want to repair, and then click Next.
• Select your user account and click Next.

On the System Recovery Options menu you will get the following options:

• • Startup Repair
    System Restore
    Windows Complete PC Restore
    Windows Memory Diagnostic Tool
    Command Prompt
• Select Command Prompt
• In the command window type in notepad and press Enter.
• The notepad opens. Under File menu select Open.
• Select "Computer" and find your flash drive letter and close the notepad.
• In the command window type e:\frst.exe (for x64 bit version type e:\frst64) and press Enter
  Note: Replace letter e with the drive letter of your flash drive.
• The tool will start to run.
• When the tool opens click Yes to disclaimer.
• Press Scan button.
• It will make a log (FRST.txt) on the flash drive. Please copy and paste it to your reply.

Let me know how things go. If you at any point have trouble using FRST, please stop and post back here to let me know.

[w3junky]

Appears the entire registry is messed up as I don't see any files from a command prompt. Anyways, I ended up reformatting the PC and reloading the OS. No worries though, I had necessary file backups already done a few days ago. But thanks again for your time on this, and you can close out the case.
