This is a relatively harmless macro virus. It infects a Normal template upon closing an infected document. Other documents are infected upon their opening and creating.
Upon exiting Word in one case in ten, the virus displays a question as follows:
Good Luck 98
5912 + 6118 - 65 * 12 = 11265 ?
[ Yes ] [ No ]
This equation may be right or wrong. If a user gives the right answer, the virus displays the message:
Congratulation !
Congratulation, you have done a great job !
Otherwise the virus displays two other messages:
Sorry !
Sorry, you are wrong !
Happy Birthday !
Today (9/24/) is my birthday.
There is the current year. And then the virus changes the system date to 9/24/.
You have to check a system's date on a computer after disinfection.
