Been working on this machine for many hours. Could not get ahead of the issue. Removed HD to get data off and reclone but in doing so ran more scans and most importantly reset permissions on all folders and files. So when I put the HD back in the original computer I was able to run Combofix and get ahead of this beast.

some entries from malewarebytes scans;

Files Infected:
C:\WINDOWS\system32\us?rinit.exe (Rogue.Antivirus2010) -> Quarantined and deleted successfully.

Registry Keys Infected:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Userinit (Trojan.Agent) -> Quarantined and deleted successfully.

Files Infected:
C:\System Volume Information\_restore{718E0156-3611-4DD7-A737-6E3C9A8028F5}\RP47\A0006289.exe (Trojan.FakeAV) -> Quarantined and deleted successfully.
C:\System Volume Information\_restore{718E0156-3611-4DD7-A737-6E3C9A8028F5}\RP47\A0006290.dll (Trojan.Agent) -> Quarantined and deleted successfully.
C:\WINDOWS\system32\drivers\vbma558a.sys (Trojan.Agent) -> Delete on reboot.
C:\Documents and Settings\xxxx\Application Data\Microsoft\stor.cfg (Malware.Trace) -> Quarantined and deleted successfully.
C:\WINDOWS\system32\us?rinit.exe (Rogue.Antivirus2010) -> Quarantined and deleted successfully.


my AVG logs are gone since I had to remove AVG to run Combofix.

Wanarp.sys was probably to most persistently flagged file. I replaced it with a known good.

Basically at this point I'm just hoping to get a clean bill of health on the attached logs and maybe some feedback on what this was. This is by far the worst infection I've ever fought.

thanks for any help,

ChazIT

Hello and welcome to Bleeping Computer

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

If you have since resolved the original problem you were having, we would appreciate you letting us know. If not please perform the following steps below so we can have a look at the current condition of your machine.

If you have not done so, include a clear description of the problems you're having, along with any steps you may have performed so far.

Upon completing the steps below another staff member will review and take the steps necessary with you to get your machine back in working order clean and free of malware.

If you have already posted a DDS log, please do so again, as your situation may have changed.
Use the 'Add Reply' and add the new log to this thread.

Thanks and again sorry for the delay.

We need to see some information about what is happening in your machine. Please perform the following scan:
  • Download DDS by sUBs from one of the following links. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explaination about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Information on A/V control HERE

We also need a new log from the GMER anti-rootkit scanner. Please first disable any CD emulation programs using the steps found in this topic:

Why we request you disable CD Emulation when receiving Malware Removal Advice

Then create another GMER log and post it as an attachment to the reply where you post your new DDS log. Instructions on how to properly create a GMER log can be found here:

Thanks Casey,
Yes I was able to finally completely resolve. Having the HD out of the machine helped fix the permissions problems. Combining another Combofix and scans w/ AVG and malwarebytes I was able to finally get clean scans and give the computer back to my FIL.
