Hi Rick:
Well I don't believe that would be a protection at all against viruses. Why?
If I where to write a virus and knowing that reactos has such protection that would not
stop me at all. I could simply write a function to calculate the hash in the virus (or
simply tell the OS to do it for me) and update such database. Look at windows file
protection, virus laugh at it. I think the verification of the PE checksum is enough to
tell if a file is corrupt and would be faster wich means a faster load. If you want to
know some more about viruses look for the e-zines of 29A on the internet to find out more
about the subject. Their articles are as advanced as those in phrack (the latest). I think
there is not solution for viruses, users will always do insecure things and viruses will
be there waiting for them to do it.
Regards
Waldo

Sun will be releasing Solaris 10 shortly as a commercial product available for purchase.
There is a new file system that is 128-bit, and is protected by md5 checksums, I think
this is a great idea for reactos. I think before a program executes there should be a
binary verifier that checks this checksum and then allows the program to run. This would
help in deterring Windows viruses from attaching themselves to reactos binaries. Since
ReactOS is open source it will be harder to protect a binary if there is an attack and a
malicious user replaces a dll or an exe. Perhaps this can be done using a small xml file
or a txt file called md5sums or something. Please let me know what you think.
