I'm currently working on a computer that has the Trojan:DOS/Alureon.E virus. It wasn't really noticeable until it started hiding my siblings' files that were being synced with iCloud and iCloud started removing the files from their laptops. My first step is usually to pop the drive out and make a backup of it but I didn't bother to do that this time. Instead, I decided to try to clear things up on the infected PC. This allowed the virus to continue hiding files. When my father called me to tell me that their files were being deleted, I pulled the plug on it, pulled the drive and scanned it with MS Security Essentials. That's how I found out that it is Trojan:DOS/Alureon.E.

So, I used my Google Fu and found this thread. I've downloaded all of the utilities listed in the thread to a flash drive, disabled Security Essentials, and ran unhide.exe. The next post will contain my miniToolBox Results.txt file.

I decided rather than pasting the results in here, I'd throw them up on one of my servers and link to them. So, here is the Result.txt file. Let me know if there is anything else I should be looking out for while I'm working on this.

When I lost all of my progress on this, I enabled Security Essentials again. It found that the computer is now infected with Trojan:Win32/Sirefef.AH

These are some of the nastiest bugs I've encountered. I suppose there's a completely different strategy I need to take with this one. Time to do more searching.

hello, can you do these?/


Please download TDSSKiller.zip and and extract it.
  • Run TDSSKiller.exe.
  • Click Start scan.
  • When it is finished the utility outputs a list of detected objects with description.
    The utility automatically selects an action (Cure or Delete) for malicious objects.
    The utility prompts the user to select an action to apply to suspicious objects (Skip, by default). Let the options as it is and click Continue
  • Let reboot if needed and tell me if the tool needed a reboot.
  • Click on Report and post the contents of the text file that will open.

    Note: By default, the utility outputs the log into system disk (it is usually the disk with installed operating system, C:\) root folder. The Log has a name like: TDSSKiller.Version_Date_Time_log.txt.



If TDSSKiller does not run, try renaming it. To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to these[/color] instructions. In some cases it may be necessary to redownload TDSSKiller and randomly rename it before downloading and saving to the computer.

I'm currently running a full scan with MBAM. I was unable to run TDSKiller last night, no matter how I renamed it. I even downloaded it again on my PC, renamed it, copied it to a flash drive and put it on the infected PC. It still would not run. I will attempt to run it again after the MBAM scan finishes.

Something is still hiding everything, too. So, I'll have to run unhide again before the miniToolBox. If my siblings didn't have important school work on this, I'd just cut my losses and wipe the disk.

I'll let you know the outcome (if any) of TDSKiller and ESET when I get to run them.

When MBAM finished its scan, it had found about 350 infected files. It was able to clean them.

Running FixTDSS.exe found an infected MBR and was able to fix it.

I ran unhide.exe again. Then I ran the ESET Online Scanner and it found nothing.

I also ran Minitoolbox again. Here are the results from that.

It looks to me like it might be clean, now. Let me know what you think.

Rerun MBAM (MalwareBytes) like this:

Open MBAM in normal/regular mode and click Update tab, select Check for Updates,when done
click Scanner tab,select Quick scan and scan (normal mode).
After scan click Remove Selected, Post new scan log and Reboot into normal mode.

You need to to reset your Hosts file.
Click Run in the File Download dialog box or save MicrosoftFixit50267.msi to your Desktop and double-click on it to run. Then just follow the prompts in the Fix it wizard.



You have some Toolbars you should remove thru the Control Panel/Add/Remove... These are really just spyware and no body uses them.



Important Note: Your version of Java is out of date. Older versions have vulnerabilities that malicious sites can use to exploit and infect your system.Please follow these steps to remove older version Java components and update:

  • Close any programs you may have running - especially your web browser.
Go to Posted Image > Control Panel, double-click on Add/Remove Programs or Programs and Features in Vista/Windows 7 and remove all older versions of Java.
  • Check (highlight) any item with Java Runtime Environment (JRE or J2SE) in the name.
  • Click the Remove or Change/Remove button and follow the onscreen instructions for the Java uninstaller.
  • Repeat as many times as necessary to remove each Java versions.

  • If using Windows 7 or Vista and the installer refuses to launch due to insufficient user permissions, then Run As Administrator.
  • When the Java Setup - Welcome window opens, click the Install > button.
  • If offered to install a Toolbar, just uncheck the box before continuing unless you want it.
  • The McAfee Security Scan Plus tool is installed by default unless you uncheck the McAfee installation box when updating Java.
Note: The Java Quick Starter (JQS.exe) adds a service to improve the initial startup time of Java applets and applications but it's not necessary.
To disable the JQS service if you don't want to use it:
  • Go to Start > Control Panel > Java > Advanced > Miscellaneous and uncheck the box for Java Quick Starter.

I ran a full scan with MBAM, since I had the time. It found nothing.

I fixed the hosts file, removed all of those pesky toolbars, and updated java.

Thank you for all of your help. This definitely would have taken longer without it.
