Hi Timsgirl. Download the latest version of Combofix.exe from
here and save it to your Desktop.
Doubleclick on combofix.exe and follow the prompts. A window will open with a warning. Type "1" (and Enter) to start the fix. When the scan completes, Disk Cleanup will run and then a text window with your log will open. Please copy and paste that log back here.
A caution - do not touch your mouse/keyboard until the scan has completed. The scan will temporarily disable your desktop, and if interrupted may leave your desktop disabled. If this occurs, please reboot to restore the desktop.
Copy this log in your next reply together with a new HijackThis log.
Also go
here and download Silent Runners.vbs to a new folder on your Desktop (Clicking the the download link works if you use IE. If you use FireFox, rightclick on the link and choose "Save Link As") and run it. It generates a log too. It takes a minute or two and it will notify you with a popup when your log is ready (make sure you wait for the popups please) Please post the information back in this thread too (you may need to make a couple of posts). If your antivirus program queries the script, allow it to run. It's not malicious.
