There is a standard Aurora removal procedure now, but judging from your HTJ log, it doesnt look like you've done it yet:
You will need to disconnect from the Internet for most of the cleaning procedures, so you should print out the following instructions or save them into a text file using Notepad.
Download the trial version of Ewido Security Suite here:
http://www.ewido.net/en/download/
Install it, and update the definitions to the newest files. Do NOT run a scan yet.
Download Nailfix from here:
http://www.noidea.us/easyfile/file.php?download=20050515010747824
Unzip it to the desktop but please do NOT run it yet.
Next, reboot your computer in Safe Mode by doing the following:
1) Restart your computer
2) After hearing your computer beep once during startup, but before the Windows icon appears, press F8.
3) Instead of Windows loading as normal, a menu should appear
4) Select the first option, to run Windows in Safe Mode.
For additional help in booting into Safe Mode, see the following site:
http://www.pchell.com/support/safemode.shtml
Once in Safe Mode, double-click on Nailfix.cmd. Your desktop and icons will disappear and reappear, and a window should open and close very quickly --- this is normal.
Then run Ewido, and run a full scan. Save the logfile from the scan.
Next run HijackThis, click Scan, and check:
R1 - HKCU\Software\Microsoft\Internet Explorer\SearchURL,(Default) = websearch.drsnsrch.com/q.cgi?q=
R3 - Default URLSearchHook is missing
F2 - REG:system.ini: Shell=Explorer.exe C:\WINDOWS\Nail.exe
O4 - HKLM\..\Run: [flxhpjl] c:\windows\system32\gsrkgd.exe
O23 - Service: System Startup Service (SvcProc) - Unknown owner - C:\WINDOWS\svcproc.exe
Close all open windows except for HijackThis and click Fix Checked.
Now click on the "Config" button in the lower right corner of HijackThis' main window.
In the next window. click on the "Misc Tools" button at the top then click the "Delete an NT service" button. Type the following in the box and click OK:
svcproc
- Open Windows Explorer, and in the Folder Options->View settings under the Tools menu, select "show hidden files and folders", and uncheck "Hide protected operating system files" and "Hide extentions for known file types".
-Locate and delete the following files if found (ewido may have deleted some of them already):
C:\WINDOWS\Nail.exe
c:\windows\system32\gsrkgd.exe
C:\WINDOWS\svcproc.exe
- Empty your Recycle Bin and reboot normally.
- Run HijackThis again and post the new log it generates, as well as the log from the Ewido scan.
