New subject: ReactOS and Viruses

25 Nov 2004

Hi Thomas:

There are some parts of your e-mail that I can't understand but I believe you try to
give some kind of solution. And yes I think is correct at some point, I was wondering once
about that, to do the same with native applications as for example what is done with java
applets running in the browser. Containing them to some set of files. I think that yes it
would be good to prevent applications corrupting other files and such things. And in fact
could be great for advanced users But ...

1 - That is not a solution for viruses, there are kernel mode virus and trojans I wonder
how that can get there. At the end human intelligence can't be stopped that easy and
of course the opposite also happens, ignorance could be huge. I wonder how a virus like
the I love you that can be written in a couple of minutes could spread that far. Believe
me that won't work.

2 - That should not be enabled by default, sometimes if you present a password to users
they will get lost. That happened to some users that switched from win98 to an NT based
one. That was news, and was true. With the solution you propose there will be a lot that
will press the Yes. Eh I even know ppl that click whatever they please when a message box
appears.

Regards
Waldo

Hi why would it be a could a idea simply becures we eliminate a lot of old viruses but we
could
allso make a function theire hold all exe files from execute when they contain some
strange
command f.eks the delete or format funtion or some other stuff or some kind of database
and the
send a signal out

Maybe
Reactos->MaybeVirusFile(Filename,Path);
VirusApps<-TestingFile(Filename,Path);

Ekstra Idea:
And a funtion to Stop new apps from run (REGEDIT RUNAPPS etc.)
Some New viruses use that way to start all the time and the user could be asked

NEW APP STARTING UP

RUN THE APP [X] DISMISS THE APP [ ] VIRUS TEST APP [ ]

Information about file

NEWER SHOW AGAIN [X]

And then make a group of apps that run i secure mode FOLDER SECURERUN
and then make a group of apps that run i unsecure mode FOLDER UNSECURERUN
So those in SECURE can´t change the reg and delete file e.g.
don´t know just and idea

but think people should care more about getting reactos to work...

  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 Waldo
