Re: Windows Firewall Detecting Sinowal.Trojan

Hello again, BluBerri.

Please copy this page to Notepad and Save it to your Desktop in order to assist you when carrying out the following instructions.

Before beginning the fix, read this post completely. If there's anything that you do not understand, kindly ask your questions before proceeding.
Ensure that there aren't any opened browsers when you are carrying out the procedures below.

It is IMPORTANT that you don't miss a step & perform everything in the correct order/sequence.

The computer had AVG installed in it
It appears that you now have F-Secure antivirus installed. Is this correct?

------------------------------------------------------

Close any open browsers.

Disable your antivirus and antispyware applications, usually via a right-click on the System Tray icon. They may otherwise interfere with ComboFix.

Open Notepad and copy/paste all the text in the quotebox below into Notepad:

Collect::
c:\windows\system32\TDSSwxprjkwc.0ll
c:\windows\system32\TDSSyoaqtvub.0ll
Save this Notepad file as CFScript.txt to your Desktop and then close the file.





Referring to the picture above, drag CFScript onto ComboFix

If you are prompted to update ComboFix, please click Yes

Your desktop may go blank. This is normal. It will return when ComboFix is done. ComboFix may reboot your machine. This is normal.

When finished, it shall produce a log for you. Please post that log, ComboFix.txt in your next reply.

Note:
Do not mouseclick ComboFix's window whilst it's running. That may cause it to stall.


When CF finishes running, the ComboFix log will open along with a message box--do not be alarmed.

With the above script, ComboFix will capture a file to submit for analysis.

Ensure you are connected to the internet and click OK. A browser will open. Simply follow the instructions to copy/paste/send the requested file.


Please let your helper know you successfully submitted the file.


------------------------------------------------------

Please download HijackThis and Save it to your Desktop.

Alternate link

Double-click on the file you just downloaded. Click 'Run' or 'Install' and follow the prompts to install.

It will by default install to the directory - C:\Program Files\Trend Micro\HijackThis

Upon install, HijackThis should open for you.

Should it not open, navigate to C:\Program Files\Trend Micro\HijackThis and double-click on HijackThis.exe

1. If it gives you an intro screen, just choose 'Do a system scan and save a logfile'.
2. If you don't get the intro screen, just hit 'Scan' and then click on 'Save log'.
3. Please post the HijackThis log in your next reply. Do not fix anything in HijackThis since they may be harmless.
4. Close HijackThis now please.

Please post the following in your next reply:
