Quick Research: I did a Google search on "WebSpecials remove" and located a good description
from http://www.scanspyware.net/info/WebSpecials.htm. It says that
"WebSpecials is an adware that brings frequent advertisements to your computer screen."
What I Did:
1. Looked at c:\program files\WebSpecials, found the file, and failed to delete it directly:
>dir c:\program files\WebSpecials
webspec.dll
...
>rmdir c:\program files\WebSpecials
webspec.dll in use
2. Run HijackThis > "Open the Misc Tools section" > "Delete a file on reboot",
select c:\program files\WebSpecials\webspec.dll, and reboot the system.
