Hikaru.exe

hikaru.exe, alse known as Sadako virus in Japan, was a Japanese screamer joke application created by shizuka. It is a variant of the Win32.Joke_Ghost joke program.

If the user runs it, it doesn't seem to do anything. However it silently becomes present in the operating computer's memory and triggers a payload at random times which shows a full-screen picture of a ghost girl, similar but not the same as McDonalds.exe, with a scream sound effect. It quickly spread over the Internet in Japan in the early 2000s. However, it didn't become as popular as its cousin. Some have complained that even when restarting the computer, the application will still continue its usual behavior.

The most recent version of this virus is "4.0v".
