Win32/Sirefef.DA trojan

[CRD72]

Hi,

My ESET antivirus has notified me that I am infected with the win32/Sirefef.DA trojan. It says that it is in the operating memory and that it could not remove it. If someone would be able to help me remove it I would greatly appreciate.

Thank you for your time.

Welcome to the Malware Removal Forum.

Please read ALL of this message including the notes before doing anything.

Pleases follow the instructions in the below link:

READ & RUN ME FIRST. Malware Removal Guide


and attach the requested logs when you finish these instructions.

• **** If something does not run, write down the info to explain to us later but keep on going. ****
• Do not assume that because one step does not work that they all will not. MGtools will frequently run even when all other tools will not.

• After completing the READ & RUN ME and attaching your logs, make sure that you tell us what problems still remain ( if any still do )!

Helpful Notes:

1. If you run into problems trying to run the READ & RUN ME or any of the scans in normal boot mode, you can run the steps in safe boot mode but make sure you tell us what you did later when you post logs. See the below if you do not know how to boot in safe mode:
   • Starting your computer in Safe mode
2. If you have problems downloading on the problem PC, download the tools and the manual updates for SUPERAntiSpyware and Malwarebytes ( links are given in the READ & RUN ME) onto another PC and then burn to a CD. Then copy them to the problem PC. You will have to skip getting updates if (and only if) your internet connection does not work. Yes you could use a flash drive too but flash drives are writeable and infections can spread to them.
3. If you cannot seem to login to an infected user account, try using a different user account (if you have one) in either normal or safe boot mode and running only SUPERAntiSpyware and Malwarebytes while logged into this other user account. Then reboot and see if you can log into the problem user account. If you can then run SUPERAntiSpyware, Malwarebytes, ComboFix and MGtools on the infected account as requested in the instructions.
4. To avoid additional delay in getting a response, it is strongly advised that after completing the READ & RUN ME you also read this sticky:
   • Don't Bump! It Only Hurts You!!!

Any additional post is a bump which will add more delay. Once you attach the logs, your thread will be in the work queue and as stated our system works the oldest threads FIRST.

I was also having redirecting problems with FireFox, so I followed the steps and here is my GooredFix logfile:

I was also having redirecting problems with FireFox, so I followed the steps and here is my GooredFix logfile:

If you followed these steps then where is the TDSSKiller log also?

I would also like to see logs from running the other procedures I linked you to:

• SUPERantispyware
• Malware Bytes
• Combofix
• Rootrepeal (unless on 64 bit)
• MGTools

Then you will have finished running the procedures and I can properly analyse all the logs.

[CRD72]

I've run all of the scans that were asked and here are the logs.

And here is the MGTools logs.

Please also download MBRCheck to your desktop

• Double click MBRCheck.exe to run (vista and Win 7 right click and select Run as Administrator)
• It will show a Black screen with some information that will contain either the below line if no problem is found:
  • Done! Press ENTER to exit...
• Or you will see more information like below if a problem is found:
  • Found non-standard or infected MBR.
  • Enter 'Y' and hit ENTER for more options, or 'N' to exit:
• Either way, just choose to exit the program at this point since we want to see only the scan results to begin with.
• MBRCheck will create a log named similar to MBRCheck_07.16.10_00.32.33.txt which is random based on date and time.
• Attach this log to your next message. (See: HOW TO: Attach Items To Your Post )
