F-Secure Virus Descriptions : Satria

Satria is a typical boot sector virus, which only spreads from a machine to another via floppy disks and propogates when a machine is booted with an infected floppy in drive A:. After this all floppies get infected during access.

Satria activates on the fourth of July. When an infected machine is booted on this date, the virus displays a graphic which says 'I <heart> U'. Otherwise the virus just spreads.

Satria also contains two unencrypted texts which are never displayed: 'My Honey B'day' and 'SATRIA'.

VARIANT:

Satria.B

This version displays a slightly different screen when activating. It also overwrites the original MBR without saving a copy of it.
