    Close all Windows except HijackThis and click on "Fix Checked".

    Option 1: Possible Foistware/ Borderline Spyware: NetAssistantBHO
    Foistware is not malware but is bundled with another unrelated program and installs without you knowledge or permission. I recommend removal.
    Bundled with Freeze.com_Toolbar - a Softomate Toolbar variant - Softomate customizes toolbars to customers needs. The dll files for their toolbars contain some spyware/adware functionality, although not all of the toolbars use this. Some of the toolbars are fine to have, so every case is different. Your choice.

    Special instructions for Shockwave Updater:
    Flash player is known for leaving behind old insecure files. It is better to clean out the entire entry, uninstall, then reinstall:

    • Boot into Safe Mode
      [o] Restart your computer and start pressing the F8 key on your keyboard.
      [o] Select the Safe Mode option when the Windows Advanced Options menu appears, and then press ENTER.
    • Double-click the Flash Player Uninstaller setup on the desktop and run the uninstaller program.
    • Reboot your computer to complete the uninstall.
    • Download latest version of Flash Player HERE and save to the desktop.
    • . Double click the setup and run to install. Reboot when through.
    • Once the new version is installed, follow the directions to disable the auto-updater.
      [1] Navigate to the Shockwave Welcome page:http://www.adobe.com/shockwave/welcome/
      Note: The context menu can be accessed from any Shockwave movie if the context menu has been enabled by the author, but this URL was provided to simplify the process.
      [2] Windows: Right click the Shockwave movie.
      [3] From the drop down menu choose "Properties".
      [4] Uncheck the box next to "Automatic Update Service" to disable the auto update feature.

    Please Download SDFix HERE and save it to your Desktop.
    • Double click SDFix.exe and it will extract the files to %systemdrive%
      (Drive that contains the Windows Directory, typically C:\SDFix)

      Boot into Safe Mode
    • Restart your computer and start pressing the F8 key on your keyboard.
    • Select the Safe Mode option when the Windows Advanced Options menu appears, and then press ENTER.

      Run SDFix
    • Open the extracted SDFix folder and double click RunThis.bat to start the script.
    • Type Y to begin the cleanup process.
    • It will remove any Trojan Services and Registry Entries that it finds then prompt you to press any key to Reboot.
    • Press any Key and it will restart the PC.
    • When the PC restarts the Fixtool will run again and complete the removal process then display Finished, press any key to end the script and load your desktop icons.
    • Once the desktop icons load the SDFix report will open on screen and also save into the SDFix folder as Report.txt
    • Attach Report.txt back here

    Rescan with HijackThis and include new log in next reply, along with SDFix Report.

    Sorry- I missed this. didn't realize it was an issue since you are loading the program: Description: This is a valid program but it is not required to run on startup.

    O4 - HKCU\..\Run: [DW6] "C:\Program Files\The Weather Channel FW\Desktop\DesktopWeather.exe"


    Run Eset NOD32 Online AntiVirus Scanner HERE

    Note: You will need to use Internet Explorer for this scan.
    • Tick the box next to YES, I accept the Terms of Use.
    • Click Start
    • When asked, allow the Active X control to install
    • Disable your current Antivirus software. You can usually do this with its Notification Tray icon near the clock.
    • Click Start
    • Make sure that the option "Remove found threats" is Unchecked, and the option "Scan unwanted applications" is checked
    • Click Scan
    • Wait for the scan to finish
    • Re-enable your Antivirus software.
    • A logfile is created and located at C:\Program Files\EsetOnlineScanner\log.txt. Please include this on your post.
    If this log is clean and the problems have been resolved, I'll have you remove the cleaning tools.

    I don't open files with a .doc format. Sorry. I have been experiencing an extremely slow internet all day- not site related.

    However, the embedded link I left is good- I just brought the site up using it. Please give it another try.
