Description:
This program installs an IE toolbar and changes the start page without user consent. During installation there is no possibility to choose a directory, the program does not have a visible uninstaller. Executing the installer manually removes the toolbar, but some files will not be removed.
The toolbar is supposed to work like a search engine. And it in fact does find some good results but as soon as the user clicks on a link it connects to another URL for a short time before it finally goes to the desired page.
Removal Instructions:

Installed Software List:

You can try to uninstall products with the names listed below; for items identified by other properties or to avoid malware getting active again on uninstallation, use Spybot-S&D or RunAlyzer to locate and get rid of these entries.
  • Products that have a key or property named "Accoona Toolbar".

Files:

Please use Windows Explorer or another file manager of your choice to locate and delete these files.
  • The file at "<$PROGRAMFILES>\Accoona\quiesce.exe".
  • The file at "<$PROGRAMFILES>\Accoona\showbar.exe".
  • The file at "<$PROGRAMFILES>\Accoona\tbquiesce.exe".

  • The file at "<$WINDIR>\acc1.txt".
  • The file at "<$WINDIR>\ncc1.txt".

  • The directory at "C:\Program Files\Accoona".
