Katrin blogged previously about the new Bagle variant that spreads via emails with Olympic-themed content ("2006 Torino Winter Games FREE Tickets" and so on).
This is not the first time winter Olympic games are being targeted by computer viruses. During the 1994 Lillehammer Olympic games a Swedish virus writing group got some coverage for their Olympic-themed virus, known as Virus.DOS.VCL.Olympic.1440.
The virus was programmed to overwrite the hard drive of the infected machine on the starting day of the games, and then display this message:
Kristin and Haakon were the mascots of the 1994 games and Antonio was a reference to Juan Antonio Samaranch, the president of International Olympic Committee at the time.
Do note that just like VCL.Olympic, Bagle.FY doesn't seem to be widespread.
