Removal Instructions:

Files:

Please use Windows Explorer or another file manager of your choice to locate and delete these files.
  • The file at "<$SYSDIR>\IEPlugin.dll".
Make sure you set your file manager to display hidden and system files. If Bulla uses rootkit technologies, use our RootAlyzer or our Total Commander anti-rootkit plugins.
You will have to use a global search for files without a name specified. Be extra careful, because just the name might not be enough to identify files!

Registry:

You can use regedit.exe (included in Windows) to locate and delete these registry entries.
  • A key in HKEY_CLASSES_ROOT\ named "IEPlugin.Plugin", plus associated values.
  • Delete the registry key "{3E8A1971-45A5-45EE-828B-8C78431C0BD4}" at "HKEY_CLASSES_ROOT\CLSID\".
  • Delete the registry key "{B6B3E6EB-A7DE-4FF5-AF28-795CE0A3A24E}" at "HKEY_CLASSES_ROOT\Interface\".
  • Delete the registry key "{8F358C54-381D-4205-96B6-4A4D6D2EC289}" at "HKEY_CLASSES_ROOT\TypeLib\".
  • Delete the registry key "IEPlugin" at "HKEY_LOCAL_MACHINE\SOFTWARE\".
If Bulla uses rootkit technologies, use our RegAlyzer, RootAlyzer or our Total Commander anti-rootkit plugins.

Browser:

The following browser plugins or items can either be removed directly in your browser, or through the help of e.g. Spybot-S&D or RunAlyzer.
  • Look for ActiveX software installed from "www.bulla.com".
  • Please check your bookmarks for links to "http://startpage.ms".
  • Please remove Browser Helpers named "IEPlugin".
