This is a complex virus from Taiwan. It has been spread in at least a
fake RAR 2.5 beta version.
Olivia activates on the 10th of April and the 23rd of December. On
these dates it will open the CD-ROM drive of the machine, ask the user
to insert a music CD and then it starts to play the CD. After this the
virus overwrites the beginning of the hard drive and displays a message
in Taiwanese. After this the machine freezes, with music still playing.
