Write your reply.

in their documentation they say they don't need it, but as far as i'm
concerned they do... besides, a verified clean boot is the easiest, most
secure way to subvert all memory resident viruses...
i find this somewhat unlikely... int13 entry points in the bios are not
constant for all bios (if they were, viruses would be having a field
day)... now i suppose adinf could use tunneling to find the true int13
entry points... but whats to stop a virus from blocking your tunnelling
or from subverting your tunnelling? couldn't a kernel infector setup
pmode type trapping to stop even port writes?... could a conventional
virus patch the kernel in memory to acheive the same end?...
or maybe a virus would simply use it's own tunnelling to find those
entry points, save them somewhere else and then destroy the originals in
memory... or point the originals at the virus controlled copies...
also, and i know this from experience, adinf (the version i tested,
10.02 i believe) can't use the secure mode you're talking about if your
memory manager is using a stealth option (which my installation of qemm
does)...
perhaps, but your integrity files are open to attack if not stored on a
floppy disk, and a new virus could certainly be made to block the
loading of your program simply on the basis of it's exe header...
by the way, does adinf detect companion infectors? i have a couple
companion bodies on my computer but i've never seen adinf complain about
them...
that will catch ordinary stealth viruses, will that catch sector level
stealth viruses?
my, oh my... it's good to see an actual av developer in this area
again... i hear bill lambdin was looking for anyone related to adinf to
discuss a security concern a couple months ago... did he manage to get
in touch with anyone and voice those concerns?
good product by the way... i'm amazed by the speed of the crc
generation...
... Bill Gates wants YOU... ok, maybe just your money...
