I think a BHO may be causing my computer some problems. I am using XP and IE 7.0

If I leave some tabs open at the bottom of IE and then log off of the internet when I log back on and click on the tabs they will close instead of opening.

I only have five BHOs on my computer Do you think any the follow BHOs may be causing this problem and if it is how do I remove them?

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{06849E9F-C8D7-4D59-B87D-784B7D6BE0B3} "Adobe"

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{52706EF7-D7A2-49AD-A615-E903858CF284} "Netzero"

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{8853708A-2E5C-80FC-1A5C-B410077C3BE1} "not sure about this one"

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{E0FEFE40-FBF9-42AE-BA58-794CA7E3FB53} "google gears"

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{FFFFFEF0-5B30-21D4-945D-000000000000} "stardownloader"

Thanks in advance for any help,

Internet Explorer Add-ons are plug-in applications designed for Microsoft Internet Explorer Web browser. The "Manage Add-ons" lists all the third-party browser extensions installed in Internet Explorer and provides the ability to disable them selectively but cannot be used to delete them. If an add-on is disabled, Internet Explorer adds the CLSID or Class ID control to the don't load list in the registry so when launching a new instance of it, the list is checked by iexplore.exe and explorer.exe processes and never loads that control. Add-ons may be ActiveX controls, Toolbar extensions, Browser extensions and Browser Helper Objects (BHOs) which are plug-in applications designed for the Microsoft Internet Explorer Web browser. More specifically, BHOs are code modules (.dlls) that are loaded into Explorer and Internet Explorer and run automatically every time you start your browser. BHO's were designed to allow developers to extend the functionality of Windows and improve features. However, some BHO's are malicious malware components which can act as a toolbar or browser plug-in and can be difficult to remove. The BHO you're not sure about appears to be related to malware so lets do a scan.

Please download Malwarebytes Anti-Malware (v1.34) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes. Click this link to see a list of programs that should be disabled.

That's good, nothing was found.

If you still need to remove that BHO entry, an easy tool to do so is to download and use ToolbarCop.
  • Extract (unzip) the file, and save the executable to a permanent folder, not a Temp directory. This is because ToolbarCop creates the Undo (.reg) files in the same directory from where it's launched.
  • Double-click on ToolbarCop.exe to launch.
  • Scroll through the list and look for the toolbar/BHO (Object Type/Class ID) you want to remove.
    (The CLSID or Class ID is long 128 bit number composed of a combination of letters and numbers)
    -- In your case look for {8853708A-2E5C-80FC-1A5C-B410077C3BE1}.
  • Right-click (highlight) the Add-on and choose Delete the selected item.
  • Exit ToolbarCop.
  • Now open Windows Explorer, navigate to the location of that .dll file, right-click on it and choose delete.
ToolbarCop Usage Instructions if needed.

I downloaded 3.3 by mistake. What is the best way to remove 3.3 so that I can download 3.4? I do not see the application in my add or remove software control panel.

Thanks,
Yeto

It does not include an installer. Just delete the folder where you unzipped it.
