[DUG] Renaming file in use

[Rohit Gupta]

Sean,

I thought I would try this out and you are right, another crappo from 
Microsoft.  Not only can you rename the file, it also renames the path 
in the shortcut that launched it.  Another way a virus can get in.  And 
you can even rename the dll thats in use.  Further to that if you rename 
a system dll, it silently copies it from the backup.  All test on 
win2k.  Will all this really work the same way on XP, 2kserver, 
2k3server, Terminal Services, a pc using Domain Server and Longhorn ????

I would still maintain that its is idotic to rely on this mechanism. 

Any primitive virus protection thingy should foil this.  But does it ?  
:-(  Zonealarm certainly did not complain.

I despair.  Its worth the effort to write a virus to teach MS a lesson.

Just for the record OS2 had the same weakness and I created a fuss about 
it in public forums then.  :-(   But then I forget... windows has the 
basis as OS2.
