[HELP!!] Win32:Malware-gen/Win32:Downloader-PKU [trj]
« on: July 28, 2012, 04:40:33 AM »
Hi,

I've been getting warnings from Avast about these two viruses. I really help with their removal.

I've attached the logs. Let me know if additional information is needed!

Thank You!

Hi @Wazoos


I will be working on your Malware issues


You have three antivirus in the system.



Step1.

Uninstall AVG and Symantec (Programs and Features > Uninstall), and then remove orphans

AVG Remover   (64bit)

Norton Removal Tool



Step2.

Re-run OTL.exe.

  • Copy and paste the following text written inside of the quote box into the Custom Scans/Fixes box.

Code: [Select]
:files
C:\Windows\Installer\{001591a7-0e56-2c14-2a32-6028491d017e}
C:\Users\Alex\AppData\Local\{001591a7-0e56-2c14-2a32-6028491d017e}
ipconfig /flushdns /c

:commands
[CREATERESTOREPOINT]
[emptytemp]
[Reboot]
  • Then click the Run Fix button at the top.
  • Let the program run unhindered; it will reboot the system when it is done and open notepad with logreport. Attach here that logreport.
Step3.

  • Right-click on the avast! icon in the lower right corner of the screen and choose Open Avast! User Interface.
  • In the window that opens on the top right corner, click Settings.
  • In a new window that opens, choose the option Troubleshooting, Uncheck Enable avast! self-defense, and click OK.

  • Right-click on the avast! icon in the lower right corner of the screen and select avast! shield controls .
  • In the menu that appears, choose Disable Permanently. When you are prompted to turn off security, click Yes.
Note: Do not forget to turn on this option after the cleaning.




Step4.


> Download ComboFix from here and save it to your Desktop.
If you are unsure how ComboFix works please read this guide carefully.
note: ComboFix must be downloaded to your Desktop.

> Temporarily disable your AntiVirus program.
If you are unsure how to do this please read this Instruction.

> Run ComboFix. Click on I Agree!
ComboFix will check if there is a newer version of ComboFix available.
Click Yes if prompted to download.

ComboFix will display DISCLAIMER OF WARRANTY ON SOFTWARE.
Click Yes to allow ComboFix to continue.

If Recovery Console is not installed, ComboFix will offer download & installation.
Click Yes to allow ComboFix to install Recovery Console.
Note:Do not mouse-click Combofix's window while it is running.


> When the tool is finished, it will produce a log report for you. (typical location: C:\ComboFix.txt )
  Attach log reports ( ComboFix.txt) back to topic.

Update: It's been about an hour. I haven't gotten any avast popups/warnings (they use to pop up pretty frequently, at least every 5-10mins). I did turn back on the shield/self defense option after the clean up.

Logs looking good.


 Again, temporarily disable your antivirus as you did before



It is necessary to uninstall the ComboFix :
  • Click Start (or ) then Run.


    On Windows7 or Vista you may use Start Search field if Run is not available.

  • In the line of text type in (Copy) the following:
Code: [Select]
ComboFix /Uninstall
    Note that there is a space between " ComboFix " and " /Uninstall " .

    • then click OK (or press Enter ).
    Wait for the uninstall process is complete.




    Re-Run OTL and click CleanUp! button.
    This command will also remove and other tools that we used.




     I recommended to you to use MCShield if you will.
    It will prevent infection by computer via USB flash drive, mobile phone or any other memory card.
    And not only will prevent infection, but will immediately clean Memory card or external HDD

    Hi,

    So I just did all of that. Didn't run into any problems.

    I'm guessing my computer's clear of those viruses now, right?

    Thanks a lot for all the help and time you provided! I really appreciate it.
