Zero Access Alternate File System Jail

This is the second of two systems I need assistance cleaning. I have included a TDDSkiller log from just after I installed the OS (Win 7 Home 64 Bit) and one from today. Compare the partitioning of the disk... UGH. I do see the hidden file with the 16 digit numerical name and 16 digit file extention! Internet access is now history on the machine.

Included also is a new set of OTL logs, an Avast MBR log and a zipped MBR.dat file.

Do this scan on the computer.

Please download ComboFix from any of the links below, and save it to your desktop. For information regarding this download, please visit this web page: http://www.bleepingcomputer.com/combofix/how-to-use-combofix

* IMPORTANT !!! Save ComboFix.exe to your Desktop

IMPORTANT....

1. Close any open browsers.

2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

3. Do not install any other programs until this if fixed.

Double click on ComboFix.exe & follow the prompts.

• When finished, it will produce a report for you.
• Please post the C:\ComboFix.txt

Note:
Do not mouse click ComboFix's window while it's running. That may cause it to stall

Note: If you have difficulty properly disabling your protective programs, refer to this link --> http://www.bleepingcomputer.com/forums/topic114351.html

I have run Combofix as requested and cannot click anything because the links to everything is gone (...key set for deletion error). Do you want me to reboot? Please advise.

Thanks. Btw, is this MBR file clean as well as the other machine?

A restart may be required to it now.

Yes the MBR looks clean.

Herew is the Combofix log.

If this helps, it seems control of the fake desktop I'm using from the Malware partition has it's hooks in group policy.... [attachment=123849:combofix.txt]

If this helps, it seems control of the fake desktop I'm using from the Malware partition has it's hooks in group policy

That is new to me.

Can you export that group policy for my review?

****** End Of Log ******

Your log is clean.

Can you export that group policy for my review?

If you need help to export this key let me know.

I do see the hidden file with the 16 digit numerical name and 16 digit file extention! Internet access is now history on the machine.

What can you give me on this. I have nothing to verify.

Everywhere i look is clean. Internet access is good. Performanceis fine.

Gad we could help.

Time for some housekeeping

The following will implement some cleanup procedures as well as reset System Restore points:

Click Start > Run and copy/paste the following bold text into the Run box and click OK:

ComboFix /Uninstall

Delete the other tools we used.
