Trojan.Downloader

[Tagara]

Hello. So the day as I am writing this I decided to find an texturepack for the game Minecraft. The texture pack that I was looking for is an Xray pack, so that I can see through blocks. (Me, a friend and his brother are playing on a private server that I host. My friend's brother stole items for us, which was against the rules of my server. I do not wish to use cheats on other servers, this is just to find, and retrieve the lost items that he does not want to give back.)

 

So, I searched Google for an Xray-pack. The first result was from the site, Minecraftdl.com. I've heard about it before, but I never use it, I stick to Minecraftforums.net, hosted by Curse, as it is much safer there.

When I downloaded the texturepack, which should come some sort of an folder, like a zipped one etc. Instead it was an .exe, and then I was instantly alerted. I scanned the file with my Malwarebytes PRO, it did not see anything wrong with it. So after some thinking I decided to open it, as I tought it was an downloader, packed with ads (the kind that comes with different freeware, where you get to decide if you would like to download extra programs or not, much like OpenCandy.)

My Malwarebytes PRO did not pick up anything, but my AVG Internet Security 2014 did. It told me that it was an Trojan.Downloader13, or something close to that. I am not familiar to Minecraftdl.com site, and I don't really know if they give you .exe files as I just explained. If so, did AVG flag the file because it will download something (with your permission, that is) or was it an actual trojan?

I quickly downloaded Hitman Pro, it did not find anything. AVG deleted the file, and right now ESET's online scanner is running @ 50%. No detections yet. I will run Malwarebytes and AVG afterwards, just to make sure that there is nothing. Is this just because AVG doesn't like the site that the file come from?

 

Below I have attached the downloads page from Minecraftdl.com. This is the exact page that I got it from:

I hope that we can run only a few tools to check for a possible infection, or leftovers, since I have run a few other tools already.

STEP 0

RKill is a program that was developed at BleepingComputer.com that attempts to terminate known malware processes

so that your normal security software can then run and clean your computer of infections.

When RKill runs it will kill malware processes and then removes incorrect executable associations and fixes policies

that stop us from using certain tools. When finished it will display a log file that shows the processes that were

terminated while the program was running.

As RKill only terminates a program's running process, and does not delete any files, after running it you should not reboot

your computer as any malware processes that are configured to start automatically will just be started again.

Instead, after running RKill you should immediately scan your computer using the requested scans I've included.

Please download Rkill by Grinler from one of the links below and save it to your desktop.

Link 1

Link 2

• On Windows XP double-click on the Rkill desktop icon to run the tool.
• On Windows Vista/Windows 7 or 8, right-click on the Rkill desktop icon and select Run As Administrator
• A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
• If not, delete the file, then download and use the one provided in Link 2.
• If it does not work, repeat the process and attempt to use one of the remaining links until the tool runs.
• If the tool does not run from any of the links provided, please let me know.
• Do not reboot the computer, you will need to run the application again.

STEP 01

Backup the Registry:

Modifying the Registry can create unforeseen problems, so it always wise to create a backup before doing so.

• Please download ERUNT from one of the following links: Link1 | Link2 | Link3
• ERUNT (Emergency Recovery Utility NT) is a free program that allows you to keep a complete backup of your registry and restore it when needed.
• Double click on erunt-setup.exe to Install ERUNT by following the prompts.
• NOTE: Do not choose to allow ERUNT to add an Entry to the Startup folder. Click NO.
• Start ERUNT either by double clicking on the desktop icon or choosing to start the program at the end of the setup process.
• Choose a location for the backup.
  • Note: the default location is C:\Windows\ERDNT which is acceptable.
• Make sure that at least the first two check boxes are selected.
• Click on OK
• Then click on YES to create the folder.
• Note: if it is necessary to restore the registry, open the backup folder and start ERDNT.exe

STEP 02

Please run a Quick Scan with Malwarebytes

Open up Malwarebytes > Settings Tab > Scanner Settings > Under action for PUP > Select: Show in Results List and Check for removal.

Please Update and run a Quick Scan with Malwarebytes Anti-Malware, post back the report.

Make sure that everything is checked, and click Remove Selected if anything is found.

STEP 03

Please download RogueKiller and save it to your desktop.

You can check here if you're not sure if your computer is 32-bit or 64-bit

• RogueKiller 32-bit | RogueKiller 64-bit
• Quit all running programs.
• For Windows XP, double-click to start.
• For Vista,Windows 7/8, Right-click on the program and select Run as Administrator to start and when prompted allow it to run.
• Read and accept the EULA (End User Licene Agreement)
• Click Scan to scan the system.
• When the scan completes Close 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 am sorry that I reply this late. I will follow these instructions once I get home.

[AdvancedSetup]

Okay, thanks

[Tagara]

It looks like I have solved the problem.

So, what will happen to the link that I gave you, that is the download to the file that AVG flagged.

[AdvancedSetup]

Nothing.  If you're no longer having an issue and feel that it's resolved I'll go ahead and close your topic and we're done here.

 

Cheers

[Tagara]

Okay. I wish to continue with the help. It seems like Malwarebytes has picked up a backdoor. Also, it never hurts to scan your PC.

 

EDIT: https://forums.malwarebytes.org/index.php?showtopic=145100

 

Same problem as me, I have LoL installed and Malwarebytes found it, confirmed false positive. There is no backdoor.

 

Shall I still run the scans that you have told me to above?

[AdvancedSetup]

Completely up to you.  As you say - it only takes time and there is no cost so you let me know what you'd like to do.
