Adware.Searchexplorer adds various Internet Explorer buttons and a search field named Searching-4U.

When certain keywords are searched for in the Searching-4U field, various advertisements can appear on the system. This adware can track various browsing habits. It also has a possible silent update feature.

When Adware.Searchexplorer is installed, it does the following:
  1. Creates the folder named C:\Program Files\Search-Explorer, and then adds the Explbar.dll file to that folder.

  2. Creates the folder, C:\Program Files\Searching-4U, which contains the End User License Agreement (EULA) and the Uninstall.exe file.

  3. Adds the registry keys:

    HKEY_CLASSES_ROOT\SearchExplorer.SearchExplorerObj

    HKEY_CLASSES_ROOT\SearchExplorer.SearchExplorerObj1

    HKEY_CURRENT_USERS\Software\Searching-4U

    HKEY_LOCAL_MACHINE\Software\CLASSES\SearchExplorer.SearchExplorerObj

    HKEY_LOCAL_MACHINE\Software\CLASSES\SearchExplorer.SearchExplorerObj1

    HKEY_LOCAL_MACHINE\Microsoft\Windows\CurrentVersion\Uninstall\Searching-4U

    HKEY_USERS\Software\Searching-4U





Note: Removing this adware component from the system will likely cause the program that installed it to not function as intended. The uninstaller generally identifies the programs that will not work after uninstallation.
  1. Update the virus definitions.
  2. Uninstall "Toolbar - Searching-4U" and "Searching-4U" using the Add/Remove Programs utility.

For specific details on each of these steps, read the following instructions.

1. Updating the virus definitions
Symantec Security Response fully tests all the virus definitions for quality assurance before they are posted to our servers. There are two ways to obtain the most recent virus definitions:
  • Running LiveUpdate, which is the easiest way to obtain virus definitions: These virus definitions are posted to the LiveUpdate servers once each week (usually on Wednesdays), unless there is a major virus outbreak. To determine whether definitions for this threat are available by LiveUpdate, refer to the Virus Definitions (LiveUpdate).
  • Downloading the definitions using the Intelligent Updater: The Intelligent Updater virus definitions are posted on U.S. business days (Monday through Friday). You should download the definitions from the Symantec Security Response Web site and manually install them. To determine whether definitions for this threat are available by the Intelligent Updater, refer to the Virus Definitions (Intelligent Updater).

    The Intelligent Updater virus definitions are available: Read "How to update virus definition files using the Intelligent Updater" for detailed instructions.

2. Uninstalling the Adware
  1. Do one of the following:
    • On the Windows 98 taskbar:
      1. Click Start > Settings > Control Panel.
      2. In the Control Panel window, double-click Add/Remove Programs.

    • On the Windows Me taskbar:
      1. Click Start > Settings > Control Panel.
      2. In the Control Panel window, double-click Add/Remove Programs.
        If you do not see the Add/Remove Programs icon, click "...view all Control Panel options."

    • On the Windows 2000 taskbar:
      By default, Windows 2000 is set up the same as Windows 98. In that case, follow the instructions for Windows 98. Otherwise, click Start, point to Settings, point to Control Panel, and then click Add/Remove Programs.

    • On the Windows XP taskbar:
      1. Click Start > Control Panel.
      2. In the Control Panel window, double-click Add or Remove Programs.

  3. Click Add/Remove, Change/Remove, or Remove (this varies with the operating system). Follow the prompts.
  4. Repeat for "Searching-4U."

3. Scanning for and deleting the infected files
  1. Start Norton AntiVirus and make sure that it is configured to scan all the files. For more information, read the document, "How to configure Norton AntiVirus to scan all files."
  2. Run a full system scan.
  3. If any files are detected as infected with Adware.Searchexplorer, click Delete.


    Note: If you ran the Add/Remove programs applet as described in the previous section, it is possible that all the files were removed, and therefore, they will not be detected.

4. Deleting the values from the registry

WARNING: Symantec strongly recommends that you back up the registry before making any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify the specified keys only. Read the document, "How to make a backup of the Windows registry ," for instructions.


Note: This is done to make sure that all the keys are removed. The keys may not be there if the uninstaller removed them.

  1. Click Start, and then click Run. (The Run dialog box appears.)
  2. Type regedit

    Then click OK. (The Registry Editor opens.)

  3. Navigate to and delete the keys:

    HKEY_CLASSES_ROOT\SearchExplorer.SearchExplorerObj

    HKEY_CLASSES_ROOT\SearchExplorer.SearchExplorerObj1

    HKEY_CURRENT_USERS\Software\Searching-4U

    HKEY_LOCAL_MACHINE\Software\CLASSES\SearchExplorer.SearchExplorerObj

    HKEY_LOCAL_MACHINE\Software\CLASSES\SearchExplorer.SearchExplorerObj1

    HKEY_LOCAL_MACHINE\Microsoft\Windows\CurrentVersion\Uninstall\Searching-4U
