Try the latest update for the aurora infection. It's a canned speech so just ignore the unnecessary stuff :).
Please download the trial version of Ewido Security Suite here:
Install it, and update the definitions to the newest files. Do NOT run a scan yet.
Please download Nailfix from here:
Unzip it to the desktop but please do NOT run it yet.
Next, please 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:
Once in Safe Mode, please 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 please run Ewido, and run a full scan. Save the logfile from the scan.
Next please run HijackThis, click Scan, and check:
F2 - REG:system.ini: Shell=Explorer.exe C:\WINDOWS\Nail.exe
Close all open windows except for HijackThis and click Fix Checked.
Restart your computer in normal mode and please post a new HijackThis log, as well as the log from the Ewido scan.
