Virus.DOS.Italian.578 or Italian is a virus that runs on MS-DOS. It might originate from Italy, but it might not, because the text is in English. However it could have just been a translation.
Italian is a dangerous memory resident parasitic virus. It hooks INT 21h and writes itself to the end of .com files that are currently executed.
On April 25 (the same day as the Italian liberation from the Nazis in 1945), it displays the Italian flag with the following message:
_ ITALY IS THE BEST COUNTRY IN THE WORLD _
and will then erase the disk sectors. It also contains the text:
F**ks to Italian Virus Killers
Please note: the message is not censored in the real virus.
