Summary
There is no virus by this name. However, we sometimes get queries about
a messagebox that comes up in Windows saying:
Hey!
whoa! WinWindow!
OK
This message appears to be a bug in some versions of Macromedia
Directory, which is a multimedia tool often used to create
screensavers and stuff like that. This is not a virus.
