and removal
The payload for all three members of the X97M/Barisada family is the same and highly destructive. On 24 April of any year, between 14.00 hour and 15.00 hour, when closing an infected spreadsheet, the user will get a pop-up box with questions. The first pop-up box will display:

Barisada1


If you give the correct answer No, the pop-up

Barisada2


will be displayed and the user may continue without problems.

If the answer given was Yes, the user is warned

Barisada3


and shown the next question:

Barisada4


If the answer given is Yes, the user gets the message

Barisada5


and may continue safely.

However, if the answer given is No, the user gets the message:

Barisada6


and when pressing the OK button, the virus will clear all cells in all open spreadsheets thus destroying potentially precious data.
