I believe BlinkXBeat is a Toolbar that comes with a screensaver.
The correct way to remove any program you installed is to use Add/Remove Programs
from the Control Panel or Programs and Features
first, then restart the computer and delete the Program folder if it still exists. Note: With some programs its best to uninstall while in "safe mode"
If not listed there, Windows keeps Screensavers with an .scr extenstion in the C:\Windows\System2 folder. Open Windows Explorer, navigate to that folder, locate BlinkXBeat, right-click on it and choose delete.
