Hello cmhdover, welcome to our site. :)
Your log certanly does indicate "unwanted guests", including the rather nasty "Aurora" infection.
To begin with, please follow the Aurora removal instructions below carefully and fully. In addition to removing Aurora, they should clean up at least a few of the other nasties you have:
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....050515010747824
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:
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.
