Forum Rules

When posting your problem, do not run and post a ComboFix log. ComboFix is a tool that should only be run under the supervision of someone who has been trained in its use. Using it on your own can cause problems with your computer. Any posts containing CF Logs will be ignored.

To receive help, you should instead provide a detailed description of your problem, detailed word-for-word error messages that you are receiving, screenshots of strange behaviour, and your operating system. This information is much more useful to our helpers than a ComboFix log.


If you have not received help after three days, please post a link to your topic HERE.

Launch it.Click on change parameters-Select TDLFS file system

Click on "Scan".Please post the LOG report


Please download GMER from here(doesnot work on 64 bit OS)

If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
Now click the Scan button. If you see a rootkit warning window, click OK.
When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
Click the Copy button and paste the results into your next reply.

Hello will this run?


Download the FixTDSS.exe

Save the file to your Windows desktop.
Close all running programs.
If you are running Windows XP, turn off System Restore. How to turn off or turn on Windows XP System Restore
Double-click the FixTDSS.exe file to start the removal tool.
Click Start to begin the process, and then allow the tool to run.
Restart the computer when prompted by the tool.
After the computer has started, the tool will inform you of the state of infection (make sure to let me know what it said)
If you are running Windows XP, re-enable System Restore.
How do I get help? Who is helping me?

I didnot get your TDSSkiller log,it seems FIXTDSS as cured your infected mbr.

From aswmbr log,i could see that you are infected with 64 bit zero access rootkit which has been quarantined by avast.We require advanced tools to completely remove it

Read the guide here

http://www.bleepingcomputer.com/forums/topic34773.html

and create a topic here

http://www.bleepingcomputer.com/forums/forum22.html

Good luck

You did not psot the proper logs in the new topic.

Please go here....Preparation Guide ,do steps 6-9.

Create a DDS log and post it in the new topic you started Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
If GMER won't run skip it and move on.

Let me know if that went well.
How do I get help? Who is helping me?
