Comments : The Paradox 2 virus i s a very harmless one. If you
are booting with an infected disk the virus copies
itself to address $7F000 and changes the KICK-Vectors
to stay resident in memory. After the next reset the
virus patches the DoIO()-Vector to infect other disks
After the 1st infection the virus additionally patches
the ZERO-Page ($6C). This patch increases a value by 2
If this value reaches 120000 the virus executes an
endless-routine by showing a white screen. The whole
bootlock is crypted with the $DFF006-Register.
