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.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
