Name : Byte Voyager I
Aliases : No Aliases
Type/Size : Boot/1024
Clones : No Clones
Symptoms : No Symptoms
Discovered : 08-04-91
Way to infect: Boot infection
Rating : Less Dangerous.
Kickstarts : 1.2/1.3/2.0 (Just DD-Disks)
Damage : Overwrites boot.
Removal : Install boot.
Comments : If you are booting with a ByteVoyager-Infected disk
the virus copies itself to address $7F000 and changes
the KICK-Vectors to stay resident in memory. For
infection the virus uses the DoIO()-Vector ehich will
be patched after the next reset.
The ByteVoyagerVirus test for block 880 (Root of DD
Disks) so it`s very unlikely that the virus infects
a HD-Disk (BUT NOT UNTHINKABLE). The disk which will
be infected get an new name:
"Infected by BYTE VOYAGER !!!!!!"
After the 1st infection the virus installs a new
patch in the ZERO-PAGE ($6C.w). This patch checks for
an special value in memory. If this value reaches
45000 your AMIGA will break down.
The whole virusbootblock is crypted by using the
$dff006 register so you can`t read anything in the BB
