You can remove those applications by visiting Add & Remove Programs
from your Control Panel (in Windows XP) and Programs and Features
(Windows 7). Open that section and locate those two entries and click Uninstall
and follow the uninstall steps. To completely remove the applications (registry entries, temporary files, folders and leftover) I suggest using a more advanced tool like CCleaner. Download the application, install it using its own wizard and run it from the desktop. Upon starting the application use the menu on the left and locate Tools
. From there, locate those 2 applications and remove them. After this operation use the Registry
menu on the left and perform an advanced cleaning.
