PDF filename selection in Explorer activates AcroRd32Info.exe

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View
My system is using Windows XP Home with SP2. I also have Acrobat Reader
version 7.0.5 installed. I recently took note of the fact that when I
open Windows Explorer and then select (left click once on) a file name
ending in ".pdf", Windows Task Manager indicates that an executable
named "AcroRd32Info.exe" initiates and then runs for 30 seconds.

My understanding from doing a Google is that this little program is
supposed to make Acrobat Reader able to open the .pdf file faster.


Now how hard would it be for a malware author to create something that
could exploit this capability? Apparently this has been a subject of
discussion since at least July 2005:


(search for "AcroRd32Info.exe" on the page)

My question is, how smart was Adobe to create such a thing? Better yet,
since if they can write software that does this kind of thing, *anybody*
can, how smart was it for Microsoft to make such a thing possible in
their OS?

Unless I'm missing something, simply clicking on a file name ONCE could
theoretically or even factually start the downloading, installation
and-or running of *any* kind of malware.

I would like to know, if possible, how to deactivate this kind of thing.
Is it a service running in the background that allows left clicking once
on a file name to activate a program or is it something that's built
into the kernel or what?

Any serious discussion about this subject will be greatly appreciated.

I would blow Acrobat off completely. Foxit PDF Reader is lightning fast
and is far superior to Adobe Acrobat reader.

Good luck!

I've heard people talking about that program in alt.comp.freeware. Guess
it's time to give it a try. Thanks!
