Stoned.Flame is a newer version of the Stoned virus but does not
contain any significant improvements.
Like the original Stoned virus, Stoned.Flame infects hard disk MBR's
and floppy boot sectors. The special thing about this virus is that it
always saves the original boot sector in the same spot on the disk,
no matter what the disk type is. This causes data corruption on some
types of floppy disks.
After infecting the hard disk the virus stays memory-resident
occupying 1 kB of DOS base memory. When the virus is resident, all
floppies used in drive A: are infected unless write-protected.
During infection, the virus records the current month. After this it
checks the month every time it is run. When the virus detects that the
month has changed, it overwrites track 0 of the startup hard disk and
displays a picture representing flames.
Flame was reported to be in the wild in Finland in August 1993.
