Trojan.Sirefef and others (OTL, MBAM, aswMBR files attached) -- thx for yr help

Essexboy,

OTL fix ran fine but while running Quick Scan, the computer crashed. Could it have something to do with me selecting All Users for the Quick Scan? That doesn't make sense to me but thought I'd mention. After rebooting, I re-ran OTL Quick Scan and it ran fine. Then I ran ComboFix and it ran fine too.

I am attaching all the relevant logs: the output of OTL Run Fix (07182012_224451.log), the output of the successful OTL Quick Scan (OTL_07182012.Txt), the output of ComboFix (CombFix_07172012.txt), and the message I received when the PC rebooted after the crash (Crash.txt).

Two weird things are happening: (1) three icons have appeared on my desktop after the OTL Quick Scan: Desktop.ini twice and a Word document named ~SCIALS1.docx. (2) When I try to open C:\ComboFix.txt, I get a system message saying an "illegal operation attempted on a registry key that has been marked for deletion."

Given the crash and the suspect icons, I am doubtful that my system is clean. Any help would be much appreciated. I will use the PC as normal (Internet connection included) and let you know how it goes.

Thanks,
Afoyfs

Ref the illegal operation

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.


Sometimes malware does fight back and crash the system, but it is not a major problem if it only occurs once
The icons are system files and will be rehidden once we finish

After this run can you let me know what problems remain

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
  
  
  

  :OTL
  IE - HKCU\..\SearchScopes\{70D46D94-BF1E-45ED-B567-48701376298E}: "URL" = http://127.0.0.1:4664/search&s=_LDvHwHZa0jdvtz6sJjWntW1BVU?q={searchTerms}
  O6 - HKLM\Software\Policies\Microsoft\Internet Explorer\Restrictions present
   
  :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.

Both the OTL Fix and Quick Scan ran perfectly and I am attaching the log from both here.

The PC has been running fine over the past day.

Thanks,

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

• 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.

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

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

• Microsoft Windows Update
