Another Win32:Malware-gen / Win32:Downloader-PKU[Trj] thread

Hey again, been a while since I was here, figured it was time for me to get another infection so here I am, ready to be helped and as clueless as the first time essexboy saved me.

Logs attached! It’s funny, I think the last time I had issues it was also zero access, which I guess is what the mbam log hints at.

well Essexboy is in bed now…or watching olympics ;D but he or one of the other malware removers will help you…tomorrow i guess

The pleasant Avast lady will keep me company until then, she’s so calm and collected despite the constant threat she detects!

yes she will make sure this bug cant phone home and invite more friends

Hi,

WARNINGUnfortunately one or more of the infections I have identified are Backdoor Trojans, IRCBots or other Malware capable of stealing very important information. You need to stop using all Internet Banking sites, change passwords to all sites with sensitive information from a clean computer and phone your bank to inform them that you may be a victim of identify theft. More often than not, we advise users that a full reinstallation of their Operating System is the only way to ensure that their computer will ever be 100% clean again.

Unfortunately I have found what is known as the ZeroAccess rootkit on your system. It is an especially nasty infection that can take quite some time to clean as well as may have damaged your system files itself. As a warning, during the cleaning (if you choose to do so) you may lose internet access with this computer and in the end we may need to reinstall the operating system anyway depending on the extent of the infection.

If you would like to format and reinstall your Operating System please let me know and we can assist you with that.

If you would like to continue with the cleaning, please continue with the following instructions and I will be more than happy to help. :slight_smile:

Download Combofix from the link below, and save it to your desktop.
Link

Note: It is important that it is saved directly to your desktop
If you get a message saying “Illegal operation attempted on a registry key that has been marked for deletion”, please restart your computer.


IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here


Right-Click and Run as Administrator on ComboFix.exe & follow the prompts.
When finished, it will produce a report for you.
[*]Please post the C:\ComboFix.txt for further review.


I probably shouldn’t be questioning anything at this point but I’ll just ask. Is it safe to do so even though Avast seems to be actively blocking something?

Edit: So the avast warnings seemed to come every 10 minutes or so, I just waited for one, disabled it, unplugged my router after and ran combofix. It restarted my computer and when it turned on it told me that Avast was running (It wasn’t in the taskbar or the task manager so I didn’t know how to disable it again). So I pressed ok anyways, I attached the log.

I made a mistake and didn’t run it from my desktop, please let me know if I need to re-do this since it didn’t exactly go according to plan. So far, no warnings.

Is it safe to do so even though Avast seems to be actively blocking something?
Yes...while you run ComboFix please disable Avast. Even if ComboFix still says Avast is running continue with the instructions....good question. :)
I made a mistake and didn't run it from my desktop, please let me know if I need to re-do this
No no....no mistake that caused a problem, but go ahead and move the ComboFix icon to your Desktop. It will need to be there later. :) ----------

P2P - I see you have P2P software uTorrent installed on your machine. We are not here to pass judgment on file-sharing as a concept. However, we will warn you that engaging in this activity and having this kind of software installed on your machine will always make you more susceptible to re-infections and possibly Identity Theft. It likely contributed to your current situation. This page will give you further information.

Please note: Even if you are using a “safe” P2P program, it is only the program that is safe. You will be sharing files from uncertified sources, and these are often infected. The bad guys use P2P filesharing as a major conduit to spread their wares.

I would strongly recommend that you uninstall these now. You can do so via Control Panel >> Programs and Features.

Malwarebytes

I see that you have Malwarebytes already on your computer. Please open Malwarebytes, update it and then run a Quick Scan. Save the log that is created for your next reply.

Please run a free online scan with the ESET Online Scanner
[i]Note: You will need to use Internet Explorer for this scan[/i]
[*]Tick the box next to YES, I accept the Terms of Use
[*]Click Start
[*]When asked, allow the ActiveX control to install
[*]Click Start
[*]Make sure that the options Remove found threats is NOT selected and the option Scan unwanted applications is selected.
[*]Click Scan (This scan can take several hours, so please be patient)
[*]If there are threats that are found, please press List of found threats and then in the next window that opens press Export to text file…
[*]Copy and paste/or attach that log as a reply to this topic

Note If not threats are found there will not be a log created.

Alrighty, attached the logs!

Looking much better.

[*]Please open Notepad (Start → Run → type notepad in the Open field → OK) and copy and paste the text present inside the code box below:


ClearJavaCache::

DDS::
Trusted Zone: clonewarsadventures.com
Trusted Zone: freerealms.com
Trusted Zone: soe.com
Trusted Zone: sony.com

[*]Save this as CFScript.txt and change the “Save as type” to “All Files” and place it on your desktop.

[*]Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before following the steps below. They can interfere with ComboFix or remove some of its embedded files which may cause “unpredictable results”.
[*]Referring to the screenshot above, drag CFScript.txt into ComboFix.exe.
[*]ComboFix will now run a scan on your system. It may reboot your system when it finishes. This is normal.
[*]When finished, it shall produce a log for you. Copy and paste the contents of the log in your next reply.

CAUTION: Do not mouse-click ComboFix’s window while it is running. That may cause it to stall.

In your next reply please attach the new ComboFix log and let me know how your system is running. :slight_smile:

Done, so far so good. Have had no Avast warnings since the original ComboFix run, no performance issues of any kind, no odd behavior as far as I can tell.

Hi,

Good. Please do the following…

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.


Attached the results.

I think I’m clear, but I don’t know for sure. Been 2 days and your signature says to message you, I apperently don’t have access to PMs so I’m bumping this.

Thank you for bumping this. :slight_smile:

Providing there are no other malware related problems…

IT APPEARS THAT YOUR LOGS ARE NOW CLEAN :smiley: SO LETS DO A COUPLE OF THINGS TO WRAP THIS UP!! :smiley:

This infection appears to have been cleaned, but I can not give you any absolute guarantees. As a precaution, I would go ahead and change all of your passwords as this is especially important after an infection.

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

Click Start > Run and copy/paste the following text into the Run box as shown and click OK.
Combofix /Uninstall
(Note: There is a space between the …X and the /U that needs to be there.)

Clean up with OTL:

[*]Right-click and Run as Administrator OTL.exe to start the program.
[*]Close all other programs apart from OTL as this step will require a reboot
[*]On the OTL main screen, press the CLEANUP button
[*]Say Yes to the prompt and then allow the program to reboot your computer.


Any of the logs that you created for use in the forums or remaining tools that have not yet been removed can be deleted so they aren’t cluttering up your desktop.
If you didn’t already have it I would keep Malwarebytes AntiMalware though.

Here are some tips to reduce the potential for spyware infection in the future:

1. Internet Explorer. Even if you don’t use it as your main browser it should be kept up-to-date because that is the browser Windows uses for updates.
Make your Internet Explorer more secure
- This can be done by following these simple instructions:

[*]From within Internet Explorer click on the Tools menu and then click on Options.
[*]Click once on the Security tab
[*]Click once on the Internet icon so it becomes highlighted.
[*]Click once on the Custom Level button.
[*]Change the Download signed ActiveX controls to Prompt
[*]Change the Download unsigned ActiveX controls to Disable
[*]Change the Initialize and script ActiveX controls not marked as safe to Disable
[*]Change the Installation of desktop items to Prompt
[*]Change the Launching programs and files in an IFRAME to Prompt
[*]Change the Navigate sub-frames across different domains to Prompt
[*]When all these settings have been made, click on the OK button.
[*]If it prompts you as to whether or not you want to save the settings, press the Yes button.
[*]Next press the Apply button and then the OK to exit the Internet Properties page.

2. Enable Protected Mode in Internet Explorer. This helps Windows Vista users stay more protected from attack by running Internet Explorer with restricted privileges as well as reducing the ability to write, alter or destroy data on your system or install malicious code. To make sure this is running follow these steps:
[*]Open Internet Explorer
[*]Click on Tools > Internet Options
[*]Press Security tab
[*]Select Internet zone then place check next to Enable Protected Mode if not already done
[*]Do the same for Local Intranet, Trusted Sites and Restricted Sites and then press Apply
[*]Restart Internet Explorer and in the bottom right corner of your screen you will see Protected Mode: On showing you it is enabled.

3. Use and update an anti-virus software - I can not overemphasize the need for you to use and update your anti-virus application on a regular basis. With the ever increasing number of new variants of malware arriving on the scene daily, you become very susceptible to an attack without updated protection.

4. Firewall
Using a third-party firewall will allow you to give/deny access for applications that want to go online. Without a firewall your computer is susceptible to being hacked and taken over. Simply using a firewall in its default configuration can lower your risk greatly. I would personally only recommend using one of the following two below:
Online Armor Free
Agnitum Outpost Firewall Free

5. Make sure you keep your Windows OS current. Windows XP users can visit Windows update regularly to download and install any critical updates and service packs. Windows Vista/7 users can open the Start menu > All Programs > Windows Update > Check for Updates (in left hand task pane) to update these systems. Without these you are leaving the back door open.

6. WOT (Web of Trust) As “Googling” is such an integral part of internet life, this free browser add on warns you about risky websites that try to scam visitors, deliver malware or send spam. It is especially helpful when browsing or searching in unfamiliar territory. WOT’s color-coded icons show you ratings for 21 million websites, helping you avoid the dangerous sites. WOT has an add-on available for Firefox, Internet Explorer as well as Google Chrome.

7.Finally, I strongly recommend that you read TonyKlein’s good advice So how did I get infected in the first place?

Please reply to this thread once more if you are satisfied so that we can mark the problem as resolved.

All done, thank you!

:slight_smile: You are more than welcome!! Glad that we could help.
