Joke.Win.Aloap is not a trojan (altough some programs report it as such) but a joke program.
After being run it starts to shake current and all further opened application windows. This works under all versions of MS Windows.
To deactivate the joke you should open Task Manager and kill 'Aloap Window' process.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
