Win32:Atraps-pf [Trojans] Please help!
« on: July 03, 2012, 08:17:06 AM »
Hello,

Avast keeps picking up this Trojan Horse (Win32:Atraps-pf) on my system and saying it moved it to chest* however it keeps happening every so minutes.

I ran M/Bytes, it instructed me a reboot was required to remove the found infected files but then my computer just kept crashing and couldn't restart, so after doing a successfull restore to be able to get back into win 7, now I also keep getting new tabs popping up in my browser directing me to ad-sites.

I re-ran M/bytes in safe mode however, this time I did not remove the infected files to avoid system crashing again.

I would immensley appreciate any help in cleaning this for good please.

Thank you.

OK lets get at it

Warning This fix is only relevant for this system and no other, using on another computer may cause problems

Be advised that when the fix commences it will shut down all running processes and you may lose the desktop and icons, they will return on reboot

Run OTL
  • Under the Custom Scans/Fixes box at the bottom, paste in the following


    Quote
    :Files
    C:\Windows\assembly\GAC_32\Desktop.ini
    C:\Windows\assembly\GAC_64\Desktop.ini
    C:\Windows\Installer\{ca2def57-a32c-ed50-39a7-6560710f0774}

    :Commands
    [purity]
    [resethosts]
    [emptytemp]
    [CREATERESTOREPOINT]
    [Reboot]
  • Then click the Run Fix button at the top
  • Let the program run unhindered, reboot the PC when it is done
  • Open OTL again and click the Quick Scan button. Post the log it produces in your next reply.
THEN

Download and Install Combofix
 
Download ComboFix from one of the following locations:
Link 1
Link 2
 
VERY IMPORTANT !!! Save ComboFix.exe to your Desktop
 
* IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here
  • Double click on ComboFix.exe & follow the prompts.
  • Accept the disclaimer and allow to update if it asks




  • When finished, it shall produce a log for you.
  • Please include the C:\ComboFix.txt in your next reply.[/b]
Notes:
1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. Do not "re-run" Combofix. If you have a problem, reply back for further instructions.
3.  If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.



Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

Hello,

After completing the first step, OTL instructed to do a reboot - when I clicked yes, I got the blue screen (system crash).

Rebooted in normal mode anyway, OTL produced a log which is the first attachment.

I then ran a "Quick Scan" in OTL ( did not have All Users* box ticked though - not sure if I was meant to), the second attachment is the Log that that scan produced.

If my computer is clean now, should I re run M/Bytes? if not then I'll await further instruction.   I've posted this as soon as computer has rebooted so not sure yet if Avast will still be picking up Trojan or not?  If it does occur, I'll reply accordingly.

Once again though, thank you immensely for the time/help.

Hello,

I attached the new M/bytes scan.  It seems to have found 12 infected files...most are key gens from software I've downloaded but yet to install/execute.  Also I did get another system crash (blue screen) when I went to print something but not sure if this has anything to do with that...

I did not remove the infected files once again from M/bytes to avoid a possible system crash - not sure now if you want me to do this or not?

Avast doesn't seem to have picked up anymore of the Trojan issues it was detecting before.

I'll run Avast! scan and see what the comes up with also...

Thanks.

Just a quick follow up...

Ran Avast! and the scan also found infected files.  However wasn't to sure where/how to attach the required log.

C:\Qoobox\Quarantine
C:\_OTL\MovedFiles
Was the infection found in either of the above locations ?

Allow MBAM to remove all detections

Could you run a fresh OTL quick scan ensuring all users is selected

Hello,

In regards to the Avast! scan, yes it found all but two of the infected files in the c:\_otl\movedfiles location however it showed that (2) Win32:Sirefef-PL [Rtk] were also found in c:\windows\assembly\Gac_32\desktop.ini & c:\windows\assembly\Gac_64\desktop.ini and that when I went to apply the "Move to chest" command, all infected files including those in the _OTL\MovedFiles location, were moved except for the above two.  It gave an "error:access is denied (5)" message.

I have attached the latest Quick scan log ran in OTL.

I will also re-run M/bytes now and allow it to remove all infected files found and report back if any errors/system crashes occur.  Thanks.

Quick follow up...

Re ran M/Bytes and for the infected files it found to be removed, a restart was needed.  So, once again in attempting to do so - I got the blue screen system crash.  Nonetheless, I restarted and re ran M/bytes and this time no threats were found.

Regarding Avast! scan, The two infected files that were giving me the error message when attempting to "move them to chest", I simple used the delete action in Avast to erase them - along with the other infected files that were "moved to chest".

Re ran Avast! scan and no threats found with that either.

No sure if a "quick scan" with OTL is required after having done these lastest tests.  the previous scan log uploaded was just prior to these.

Thanks.

Nope looks good

Subject to no further problems   :)

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems 

Now the best part of the day ----- Your log now appears clean  :thumbsup:

A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset  System Restore points:

Run OTL
  • Under the Custom Scans/Fixes box at the bottom, paste in the following
    Quote
    :Commands
    [resethosts]
    [emptytemp]
    [Reboot]
  • Then click the Run Fix button at the top
  • Let the program run unhindered, reboot the PC when it is done
Remove ComboFix

  • Hold down the Windows key + R on your keyboard. This will display the Run dialogue box
  • In the Run box, type in ComboFix /Uninstall (Notice the space between the "x" and "/") then click OK



  • Follow the prompts on the screen
  • A message should appear confirming that ComboFix was uninstalled
Run OTL and hit the cleanup button.  It will remove all the programmes we have used plus itself. 

We will now confirm that your hidden files are set to that, as some of the tools I use will change that
  • Go to control panel
  • Select folder options (Appearance > Folder options in category view)
  • Select the View Tab.
  • Under the Hidden files and folders heading select Do not show hidden files and folders.
  • Click Yes to confirm.
  • Click OK.

Your Java is out of date. Older versions have vulnerabilities that malware can use to infect your system.
Please follow these steps to remove older version of Java components and upgrade the application.

 Upgrading Java:
  • Go to this site  and click Do I have Java
  • It will check your current version and then offer to update to the latest version
SPRING CLEAN

To manually create a new Restore Point
 
  • Go to Control Panel and select System
  • Select System
  • On the left select System Protection and accept the warning if you get one
  • Select System Protection Tab
  • Select Create at the bottom
  • Type in a name i.e. Clean
  • Select Create
Now we can purge the infected ones
  • GoStart > All programs > Accessories > system tools
  • Right click Disc cleanup and select run as administrator
  • Select Your main drive and accept the warning if you get one
  • For a few moments the system will make some calculations
  • Select the More Options tab
  • In the System Restore and Shadow Backups select Clean up
  • Select Delete on the pop up
  • Select OK
  • Select Delete
Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

Malwarebytes.  Update and run weekly to keep your system clean

Download and install FileHippo update checker and run it monthly it will show you which programmes on your system need updating and give a download link

It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit
To learn more about how to protect yourself while on the internet read our little guide  How did I get infected in the first place ?

Keep safe  :wave:
