Since near 1986, with
the Pakistani Brain boot virus, till 1995, when Win95/Boza virus was
released, the virus for DOS had their days of glory.
Without memory protection
and security features, and full of undocumented features, DOS was researched
till nearly all its secret where know. Works like Ralph Brown Interrupts
List where the bible of the DOS vxers, and advanced features where implemented
for such virus, in some points not yet surpassed by actual virus technology.
The extinction of this OS
with the come of the win32 plataforms, was the great equalizer. In a
short space of time, all vxers, be with 10 or 1 year of experience,
where put in same level.
Of course, the ones with
a good DOS base started the win32 research faster...

There are the virus I coded for the
DOS OS. Most of they are very simple, and much times, buggy. They are here without
order, advanced and simple mixed, even why I learned boot virus coding in ASM
even before I started to code some HLLs file virus.
