[Full-Disclosure] WIN XPSP2 - is this a possible way to hack?

["Gregh" <chows@xxxxxxxxxxxxxx>]

Just noticed this one by accident. 

I had downloaded, some days back, a file to install a program that I hadn't 
gotten around to setting up. The file was named "setup.exe" and sat on my 
desktop. I had been getting errors with another already installed program so 
decided to uninstall it and install it again to cure that. When I attempted to 
install the other program which I had named "this.exe", by simply double 
clicking on it, the program named "setup.exe" (which is an innocent program, 
BTW) started.
This doesn't happen on every occasion but it occurred to me if "setup.exe" was 
invisible on my desktop and deleted itself after it had been run and had been 
put there by someone wanting to install something else on my machine, that I 
could have just clicked "next" repeatedly and ended up installing the wrong 
program.

As most of you know, clicking "next" and installing without reading is about 
what most normal users do. 

Is this thing of "setup.exe" sometimes taking over a NORMAL thing from MS?

Note that I tried it with several other programs and it seems dependant on the 
way the individual program setup is configured as to whether the file 
"setup.exe" takes over where it shouldn't be or not.

Whatever, it seems a great way to install things on XPSP2 machines that 
shouldn't be there.

Greg.
