My computer is/was infected with multiple trojans

[lawlessn]

My computer HDD died whilst travelling in Vietnam. I bought a new HDD while in Vietnam and they installed windows. The installation also seemed to include malware including key loggers as I found once I installed Avast and then Malwarebytes.

 

I have since installed more anti malware software but I'd like to make sure I've removed all the malware/Trojans/key loggers before I log into any important sites (eg banking).

 

I appreciate any help.

I've attached DDS logs, screen shots and other logs relating to this issue. Please let me know if there is anything further you need.

 

Thanking you in advance

Well the logs show you have something going on.  A new clean computer should not have all those entries in the Event Logs.

 

Let's start by having you run the following please.

 

Please visit this webpage and read the ComboFix User's Guide:

• Once you've read the article and are ready to use the program you can download it directly from the link below.
• Important! - Please make sure you save combofix to your desktop and do not run it from your browser
• Direct download link for: ComboFix.exe
• Please make sure you disable your security applications before running ComboFix.
• Once Combofix has completed it will produce and open a log file.  Please be patient as it can take some time to load.
• Please attach that log file to your next reply.
• If needed the file can be located here:  C:\combofix.txt
• NOTE: If you receive the message "illegal operation has been attempted on a registry key that has been marked for deletion", just reboot the computer.

Hi,

 

Thanks for your help.

 

I have started to run combo fix and got the following pop up "Unable to create file C:\Windows\erdnt\Hiv-backup\ERDNT.INF - Registry back up will continue, but no restore information for the ERDNT program will be saved. This means that later restoration of the registry can only be done manually, by using another OS to copy back the files."

 

There is only one option to continue and that is "OK".

 

Should I continue?

 

 

[AdvancedSetup]

That is not a good sign as it would seem that something is preventing it.  Are you sure you're logged on with Admin rights?

Did you disable your antivirus while running it?

[lawlessn]

Yes antivirus disabled.

 

Since the new hard drive was set up there is only one login so I am assuming this has admin rights would that be correct? Should I click ok then cancel the program and then try again (maybe in safe mode?)

[AdvancedSetup]

Yes, please try from Safe Mode and see if it makes any difference.  If needed we can run some other scanner.

[lawlessn]

Ok, Despite trying to disable all the scanners I installed it seemed that I could not disable Spybot S&D and Comodo internet security so I just uninstalled both programs. I then restarted, disabled other malware and virus scanner and right clicked Combofix and ran it as administrator and I had no problem.

 

Here is the report:

 

Hmmm for some reason cut and paste and the paste options in the text editor above are not working so I will attached the file.

ComboFix.txt

[AdvancedSetup]

Great, glad you were able to get it to run.  If found and correct some issues for us.

 

Please go ahead and run through the following steps and post back the logs when ready. 

 

MBAR will probably alert about AppInit_DLLs and you should be able to tell it to continue to do the scan.

If not let me know.

STEP 03
Please download Malwarebytes Anti-Rootkit from here

• Unzip the contents to a folder in a convenient location.
• Open the folder where the contents were unzipped and run mbar.exe
• Follow the instructions in the wizard to update and allow the program to scan your computer for threats.
• Click on the Cleanup button to remove any threats and reboot if prompted to do so.
• Wait while the system shuts down and the cleanup process is performed.
• Perform another scan with Malwarebytes Anti-Rootkit to verify that no threats remain. If they do, then click Cleanup once more and repeat the process.
• When done, please post the two logs produced they will be in the MBAR folder... mbar-log.txt and system-log.txt

STEP 04
Please download Junkware Removal Tool to your desktop.

• Shutdown your antivirus to avoid any conflicts.
• Right click over JRT.exe and select Run as administrator on Windows Vista or Windows 7, double-click on XP.
• The tool will open and start scanning your system.
• Please be patient as this can take a while to complete.
• On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
• Post the contents of JRT.txt into your next reply message
• When completed make sure to re-enable your antivirus

STEP 05
Lets clean out any adware now: (this will require a reboot so save all your work)

Please download AdwCleaner by Xplode and save to your Desktop.

• Double click on AdwCleaner.exe to run the tool.
  Vista/Windows 7/8 users right-click and select Run As Administrator
• Click on the Scan button.
• AdwCleaner will begin...be patient as the scan may take some time to complete.
• When it's done you'll see: Pending: Please uncheck elements you don't want removed.
• Now click on the Report button...a logfile (AdwCleaner[R0].txt) will open in Notepad for review.
• Look over the log especially under Files/Folders for any program you want to save.
• If there's a program you may want to save, just uncheck it from AdwCleaner.
• If you're not sure, post the log for review. (all items found are adware/spyware/foistware)
• If you're ready to clean it all up.....click the Clean button.
• After rebooting, a logfile report (AdwCleaner[s0].txt) will open automatically.
• Copy and paste the contents of that logfile in your next reply.
• A copy of that logfile will also be saved in the C:\AdwCleaner folder.
• Items that are deleted are moved to the Quarantine Folder: C:\AdwCleaner\Quarantine
• To restore an item that has been deleted:
• Go to Tools > Quarantine Manager > check what you want restored > now click on Restore.

Then..................

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 the report.

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


STEP 06


Please go here to run the online antivirus scannner from ESET.

• Turn off the real time scanner of any existing antivirus program while performing the online scan
• 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 option Remove found threats is unticked
• Click on Advanced Settings and ensure these options are ticked:
  • Scan for potentially unwanted applications
  • Scan for potentially unsafe applications
  • Enable Anti-Stealth Technology
• Click Scan
• Wait for the scan to finish
• If any threats were found, click the 'List of found threats' , then click Export to text file....
• Save it to your desktop, then please copy and paste that log as a reply to this topic.

STEP 07
Please download the Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatibale with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit

• Double-click to run it. When the tool opens click Yes to disclaimer.
• Press the Scan button.
• It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
• The first time the tool is run, it also makes another log (Addition.txt). Please attach it to your reply as well.

[lawlessn]

Ok these steps have been completed.

 

Please note I only just installed the free codec pack (an item found in one of the scans) as part of samsung Kies software which is used to sync data between my mobile phone and pc.

 

On that point is there anyway malware could also have copied to my phone when connected as a usb device and then get back on my system after I clean it?

 

My phone has started to play up (I think its unrelated) so I am looking to restore it to factory settings and reinstall everything after I back it up with Kies. Just want to make sure that I don't reinfect my system.

 

Results:

 

Step 03:

please post the two logs produced they will be in the MBAR folder... mbar-log.txt and system-log.txt 

 

See attached mbar-log (15-50-29).txt and system-log.txt 

 

Step 04:

Post the contents of JRT.txt into your next reply message

 

See attached JRT

 

Step 05:

a logfile report (AdwCleaner[s0].txt) will open automatically. Copy and paste in reply 

** See above about Free Codec pack - In any case I removed it **

run a Quick Scan with Malwarebytes Anti-Malware, post the report 

 

See attached AdwCleaner(S0) and Mbam-log (16-50-49)

 

Step 06:

If any threats were found, click the 'List of found threats', then click Export to text file.

 

See attached ESET Online scanner log. These were all found on D drive. D Drive only contains files that were able to 

be recovered from the old hard drive after it failed. These files have not been installed. The movie 

files have also not been accessed since coping across. 

 

Step 07:

•It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.

•The first time the tool is run, it also makes another log (Addition.txt). Please attach it to your reply as well.

 

See attached: Farbar log - FRST and Farbar Log-Addition

 

I look forward to your reply.

The logs look pretty good now.  Generally speaking the PC / Phone use different types of files so not 100% but typically files from the phone won't execute on the PC and vice versa so the chances of such an infection is pretty unlikely though conceivably possible.  

 

Please Run TFC by OldTimer to clear temporary files:

• Download TFC from here and save it to your desktop.

[lawlessn]

Ok - so I don't need to do anything about those files that showed up in D drive under the ESET Scan?? 

 

I've now deleted the temp files and run the security check.... Here is a copy of the log:

[AdvancedSetup]

Please check your version of Java and Flash and update them.

 

If you're not running an SSD then look at defragging your hard drive.

 

Those files are not real infections but are flagged as the installers can and will try to install PUP (Possibly Unwanted Programs) such as conduit toolbar, and other junk like that.

I would recommend deleting them and not using CNet for such file downloads.  Try to find files where the installer is not wrapped in junkware.

 

How is the computer running now?

Are there still any signs of an infection?

[lawlessn]

Flash updated.

 

Mostly the computer seems to be good. Since the 5/12 I have twice gotten a warning from Malwarebytes about blocking outgoing IP address:

 

2013/12/12 04:48:59 +0700 ADMIN-PC admin IP-BLOCK 94.100.23.179 (Type: outgoing, Port: 49363, Process: avastsvc.exe)

2013/12/12 04:48:59 +0700 ADMIN-PC admin IP-BLOCK 94.100.23.179 (Type: outgoing, Port: 49364, Process: avastsvc.exe)

2013/12/12 07:18:12 +0700 ADMIN-PC admin IP-BLOCK 94.100.23.179 (Type: outgoing, Port: 51532, Process: avastsvc.exe)

2013/12/12 07:18:12 +0700 ADMIN-PC admin IP-BLOCK 94.100.23.179 (Type: outgoing, Port: 51533, Process: avastsvc.exe)

 

I am not sure if this is anything to be concerned with.... From memory it happened when I was recovering webpages I think. Well I know that was the case the first time can't remember if that was the case about this one I've posted above.

 

Also do I actually need to install Java?

 

And is there anything else I should do to ensure my system is safe?

[AdvancedSetup]

If the IP block is only rarely then its fine. An IP block that is persistent or continues even with your browser and email closed is an issue.

No, if you can do without Java that would be best, but if you do need it then ensure its always running the latest version.

At this time there are no more signs of an infection on your system.

However if you are still seeing any signs of an infection please let me know.

Let's go ahead and remove the tools and logs we've used during this process.

Most of the tools used are potentially dangerous to use unsupervised or if ran at the wrong time.

They are often updated daily so if you went to use them again in the future they would be outdated anyways.

The following procedures will implement some cleanup procedures to remove these tools.

It will also reset your System Restore by flushing out previous restore points and create a new restore point.

It will also remove all the backups our tools may have created.

Uninstall ComboFix (if used):

• Turn off all active protection software including your antivirus.
• Push the "Windows key" + "R" (between the "Ctrl" button and "Alt" Button)
• Please copy and past the following into the box ComboFix /Uninstall and click OK.
• Note the space between the X and the /Uninstall, it needs to be there.

Remove the rest of the tools used:

Please download OTCleanIt and save it to your Desktop. This tool will remove all the tools we used to clean your pc.

• Double-click OTCleanIt.exe.
• Click the CleanUp! button.
• Select Yes when the "Begin cleanup Process?" prompt appears.
• If you are prompted to Reboot during the cleanup, select Yes.
• The tool will delete itself once it finishes, if not go ahead and delete it by yourself.
• If asked to restart the computer, please do so

Note: If you receive a warning from your firewall or other security programs regarding OTCleanIt attempting to contact the internet, please allow it to do so.

AdwCleaner Removal:

• Double click on AdwCleaner.exe to run the tool.
• Click on Uninstall
• Confirm with Yes

ESET antivirus Removal:

• This tool can be uninstalled via the Control Panel, Programs, Uninstall

If there are any other left over Folders, Files, Logs then you can delete them on your own.

Please visit the following link to see how to delete old System Restore Points. Please delete all of them and create a new one at this time.

A lot of reading here but if you take the time to read a bit of it you'll see why/how infections and general damage are so easily inflicted on the computer. There is also advice on how to prevent it and keep the system working well. Don't forget about good, solid backups of your data to an external drive that is not connected except when backing up your data. If you leave a backup drive connected and you do get infected it can easily damage, encrypt, delete, or corrupt your backups as well and then you'd lose all data.

Nothing is 100% bulletproof but with a little bit of education you can certainly swing things in your favor.

Hi Ron,

 

I have removed the tools and restore points and created a fresh restore point. I don't have Java installed on this new hard drive so that saves me a step!

 

Thanks so much for all your help in making sure my system is safe to use again and for the sites about malware. You don't know how much of a great help you have been - You're awesome!!

 

If I do notice further problems how do I contact you?

 

Thanks heaps

Nick

PS - I will be upgrading to Malware PRO shortly! You guys have been great!
