Malwarebytes just blocked a Trojan: am i safe?


Recommended Posts

Hi everyone! happy new year! I hope you and your dear ones are safe!

Long story short, today i installed Wargaming.net official launcher, Game Center.

However, right after the download of World of Tanks started, Malwarebytes Premium blocked some IPs due to Trojans.

I immediately stopped the download and decided to install and play the game directly through Steam.

I guess the Trojan alert was caused by seeding or some kind of torrent p2p technology to deliver the game -and- malwares/trojans with it.

googling here and there it appears NOT to be a false positive, as someone stated in an old thread these IPs spread 'Mozi Linux malwares' (I don't know what they are).

However, what I'd like to know and what i'm asking you is : am I safe?

I am genuinely concerned, and a bit paranoid too, that anything of these Trojans got into my pc and/or opened a backdoor, or scanned ports (the famous "port scanning") in my local network or router. I'm kinda tech savvy but not -that- savvy.  I don't know...

i run mbam premium and bitdefender total security. Did a run of both scans + adwcleaner and nothing is found. may I rest assured like nothing happened?

 

thank you!

Please go to Control Panel, Programs, Programs and Features and uninstall the following

  • Bonjour
     

 

What does this batch file do?

C:\Users\Phior\Desktop\Google Drive.lnk -> C:\Program Files\Google\Drive File Stream\launch.bat ()

 

I'm having the Web Research team double-check on these IP blocks. There were three of them and all three were from this process.

C:\\ProgramData\\Wargaming.net\\GameCenter\\wgc.exe",

 

I'll let you know what they say.

Please run the following cleanup fix for me.

 

Please download the attached fixlist.txt file and save it to the Desktop or location where you ran FRST from.
NOTE. It's important that both files, FRST or FRST64, and fixlist.txt are in the same location or the fix will not work.

Please make sure you disable any real-time antivirus or security software before running this script. Once completed, make sure you re-enable it.

NOTICE: This script was written specifically for this user, for use on this particular machine. Running this on another machine may cause damage to your operating system that cannot be undone.

Run FRST or FRST64 and press the Fix button just once and wait.
If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log on the Desktop (Fixlog.txt) or wherever you ran FRST from. Please attach or post it to your next reply.

Note: If the tool warned you about an outdated version please download and run the updated version.

NOTE-1:  This fix will run a scan to check that all Microsoft operating system files are valid and not corrupt and attempt to correct any invalid files. It will also run a disk check on the restart to ensure disk integrity. Depending on the speed of your computer this fix may take 30 minutes or more.

NOTE-2: As part of this fix all temporary files will be removed. If you have any open web pages that have not been bookmarked please make sure you bookmark them now as all open applications will be automatically closed. Also, make sure you know the passwords for all websites as cookies will also be removed. The use of an external password manager is highly recommended instead of using your browser to store passwords.

NOTE-3: As part of this fix it will also reset the network to default settings including the firewall. If you have custom firewall rules you need to save please export or save them first before running this fix.

The following directories are emptied:

  • Windows Temp
  • Users Temp folders
  • Edge, IE, FF, Chrome, and Opera caches, HTML5 storages, Cookies and History
  • Recently opened files cache
  • Flash Player cache
  • Java cache
  • Steam HTML cache
  • Explorer thumbnail and icon cache
  • BITS transfer queue (qmgr*.dat files)
  • Recycle Bin

Important: items are permanently deleted. They are not moved to quarantine. If you have any questions or concerns please ask before running this fix.

The system will be rebooted after the fix has run.

fixlist.txt

Thanks

Hi AdvancedSetup, i really thank you for your quick reply.

1) the Bonjour service: I think it's not malicious, i had it for a long time and it belongs to icloud/apple, something that has to do with iTunes on PC. can you confirm me on this?

2) the directory "C:\Users\Phior\Desktop\Google Drive.lnk -> C:\Program Files\Google\Drive File Stream\launch.bat", I think it belongs to the application that synchronizes my google drive on my PC, can you also confirm this is not dangerous? could it be a dressed up malware?

3) right after the trojan block, yesterday, i immediately stopped the download and deleted the program listed as "C:\\ProgramData\\Wargaming.net\\GameCenter\\wgc.exe" (like i said, it's the game client that was downloading World of Tanks).

I really appreciate your investigation with your team on those IPs to check if and what they're spreading. Also, as you can see in this thread, one of that same company's engineers reported the same problem. if this can help your investigation.

 

Looking forward to your answers thanks!

I'll do the cleanup fix as soon as possible.

Yes Bonjour is part of Apple but it is not needed by a Windows computer. About the only potential reason you might need it is if you have a Apple TV connected to your computer. You could probably even still connect that without Bonjour. It's just a network discovery tool but is extremely noisy, chatty and actually creates a storm of unneeded network traffic on your computer. I have and use iTunes as well with zero issues.

I would highly recommend you uninstall it. Your computer will thank you almost guaranteed. If you find for some unknown reason it is causing you an issue it is very easy to reinstall but I've had thousands of people remove it and only a couple say they wanted it back. It's poorly written software in my opinion.

 

 

Use NOTEPAD to open this file and copy/paste it's value back here unless there is something private in there which I doubt.

C:\Program Files\Google\Drive File Stream\launch.bat

 

Well, if the file WGC.EE is now gone and you don't use it then it should no longer pose any threat.

 

 

Please go ahead and run the FIX when you have time. It will do a general clean up and verify core Operating System files, etc and do a disk check, etc.

Thanks @ParanoiaBoy

The IP blocks prevent any further interaction from that IP. There are no sings of an infection on your system. The Team replied back that that IP blocks are still valid.

Let's go ahead and run another 3rd party antivirus scan to help alleviate and reduce your concerns.

 

 

Microsoft Safety Scanner

Please make sure you Exit out of any other program you might have open so that the sole task is to run the following scan.   
That goes especially for web browsers, make sure all are fully exited out of and messenger programs are exited and closed as well
 

STEP 1

Please set File Explorer to SHOW ALL folders, all files, including hidden ones.  Use OPTION ONE or TWO of this article

https://www.tenforums.com/tutorials/7078-turn-off-show-all-folders-windows-10-navigation-pane.html

STEP 2

I suggest a new scan for viruses & other malware. This may take several hours, depending on the number of files on the system and the speed of the computer.

The Microsoft Safety Scanner is a free Microsoft stand-alone virus scanner that can be used to scan for & remove malware or potentially unwanted software from a system. 

The download links & the how-to-run-the tool are at this link at Microsoft 

https://docs.microsoft.com/en-us/windows/security/threat-protection/intelligence/safety-scanner-download

 

Look on the Scan Options & select the FULL scan.

Then start the scan. Have lots of patience. It may take several hours.

  • Once you see it has started, take a long long break;  walk away.  Do not pay credence if you see some intermediate early flash messages on the screen display.  The only things that count are the End result at the end of the run.
  • The scan will take several hours.  Leave it alone. It will remove any other remaining threats as it goes along.  Take a very long break, do your normal personal errands .....just do not use the computer during this scan.

This is likely to run for many hours as previously mentioned  ( depending on the number of files on your machine & the speed of the hardware.)

The log is named MSERT.log  and the log will be at C:\Windows\debug\msert.log

Please attach that log with your next reply.

Thank you
