Right so I've had this infection for a few months now and i thought i had gotten rid of it for good. I recently had to open my Host File to put some IP's in there and i found two very odd lines, which i tried to remove. Upon removing them, and saving the Host file, I opened the file once more to check, and they were back on. This alerted me that something was going on, so I googled a bit and saw they were probably part of a Trojan. Booted into Safe Mode and did a full system scan with Norton 2011 and Malwarebytes Anti-Malware. Norton is still scanning (Currently it has found and removed two Trojan.Gen entries), and MBAM has also found several trojans which I had previously removed. The last time the infection flared up and I noticed activity, MBAM was unable to do anything, however Norton took care of that (I guess for the time being..). Now since I have been running Norton, I haven't had any signs that point to the stuff being active...but I guess it is. Re-Formatting is not an option for me, even though I would love to do it.



Host File Entries:

SUPERAntiSpyware:

Please download and scan with SUPERAntiSpyware Free

  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If it will not start, go to Start > All Prgrams > SUPERAntiSpyware and click on Alternate Start.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and under Scanner Options, make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen and exit the program.
  • Do not run a scan just yet.
Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with SUPERAntiSpyware as follows:
  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes" and reboot normally.
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.
If you have a problem downloading, installing or getting SAS to run, try downloading and using the SUPERAntiSpyware Portable Scanner instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.

Now GMER

GMER does not work in 64bit Mode!!!!!!

Please download GMER from one of the following locations and save it to your desktop:

  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic Full Scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning

Here are the Results:

Norton: Found 3 Genuine instances of Trojan.Gen, after scanning 1,340,973 items.
Location: C:\Users\2\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\10

SUPER: Found 284 Tracking Cookies - No biggie
SUPER didn't detect anything since I already removed the infections with MBAM, If I reboot however, the trojans will simply regenerate.
Norton seems to stop them from launching, especially the Rogue.Antivirus

GMER: Found a few

GMER 1.0.15.15530 - http://www.gmer.net
Rootkit scan 2011-01-13 04:11:39

I already have, in my first post. It isn't the entire log, but it contains the important parts (Infected ones).
I didn't copy over the other stuff because it simply said how long the scan took etc...
Anyway here it is again.

Host File Entries:

122.224.6.164 cao.iwillhavebigdick.com
173.192.153.178 www.123.com


MBAM Cleaner Log:

Registry Data Items Infected:

Folders Infected:

These pretty much all regenerate on reboot or a week or two in the future, and MBAM is almost always unable to remove them fully. They don't seem to be doing any harm, but then again they are Trojans.

Oh alright, Well I don't have access to the infected PC at the moment, I will however in a few hours but the version of MBAM I had installed
was the latest, and I updated it at around 11PM EST last night. So whatever was available then. I'll post the actual versions in a few hours.

Can you not edit the log file when posting logs.

Your infection may need a deeper look:

Please follow the instructions in ==>This Guide<==.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Please include the link to this topic in your new topic and a description of your computer issues and what you have done to resolve them.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

Once you have created the new topic, please reply back here with a link to the new topic.

I only edited one thing from the log, and that was a false positive under Files. The other edit was simply to let you know I had used Norton Power Eraser with some degree of success.

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MR Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic.
The power of accurate observation is commonly called cynicism by those who haven't got it.
