welcome to the forum. our malware expert will check those logs and give you further instructions on how to move forward.

in the mean time i suggest you try malwarebytes antimalware as a first step and see if that could not solve your problem.

http://filehippo.com/download_malwarebytes_anti_malware/

download, install, update and do a scan. don't forget to remove what it finds. a system reboot might be needed.

good luck.

Thank you. I have already done that and rebooted, it removed quite a few things but it can't get rid of this problem. I appreciate the help, I have been trying for days to get rid of this thing to no avail.

Hi there lets get shot of it for you

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
    :OTL
    O4 - HKU\.DEFAULT..\RunOnce: [IsMyWinLockerReboot] msiexec.exe /qn /x{voidguid} File not found
    O4 - HKU\S-1-5-18..\RunOnce: [IsMyWinLockerReboot] msiexec.exe /qn /x{voidguid} File not found
    O4 - HKU\S-1-5-19..\RunOnce: [IsMyWinLockerReboot] msiexec.exe /qn /x{voidguid} File not found
    O4 - HKU\S-1-5-19..\RunOnce: [mctadmin] C:\Windows\System32\mctadmin.exe File not found
    O4 - HKU\S-1-5-20..\RunOnce: [IsMyWinLockerReboot] msiexec.exe /qn /x{voidguid} File not found
    [2011/12/04 15:30:05 | 000,011,058 | -HS- | M] () -- C:\ProgramData\72bs46l7510qqd65su81o88bl5bo5ucy5anfmc57ymk620
    [2011/12/04 15:30:04 | 000,011,058 | -HS- | M] () -- C:\Users\Trevor Harvey\AppData\Local\72bs46l7510qqd65su81o88bl5bo5ucy5anfmc57ymk620

    :Files
    ipconfig /flushdns /c

    :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

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

So far so good. It wouldn't let me start Avast at first but I rebooted and everything seems to work fine.

So I did a full system scan with Avast afterwards and it found 5 infected files, then I did a boot scan and it found a couple more, MBAB didn't find anything with a quick scan though. I'm going to run another full scan with both programs and see what happens.

Win32:Sirefef-FQ
Win32:Sirefef-C
Win32:Malware-gen
Win64:Sirefef-C
Win32:MalOb-HO

The MBAM finished the full scan and found nothing and Avast is at 65% with nothing found so I think it's clean, but I won't get my hopes too high until it's 100% done.

Win32:Sirefef-FQ
Win32:Sirefef-C
Win32:Malware-gen
Win64:Sirefef-C
Win32:MalOb-HO

If the above files were located in either :
Qoobox
OTL_Movedfiles

Then they were the ones we quarantined earlier.

If you are still happy tomorrow let me know and I will remove my tools

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
  • Click Start.
  • Open My Computer.
  • Select the Tools menu and click Folder Options.
  • 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:
