Exploit

One of the methods exposed allows direct control over low level features of the object, which in turn allows execution of arbitrary code. The code will run with the privileges of the target user opening the PDF document.

AcroRd32Info is a another creative pieces of crap from Adobe a package for Acrobat Reader. Embed in Windows Explorer Shell, its main role is to start an initial prefetching for PDF documents in the Memory.

To test this program behavior, you will need to open your windows task manager (ctrl+alt+del once) and browse to any folder that contained a PDF documents and stay idle. Within just few seconds AdobeRd32Info will be loaded in the background and stay in memory.That was just for browsing the folder without opening any PDF files yet.

Windows has a standard prefetch modes and its fairly stable for most of the applications out there. Having a another background prefetcher hook on explorer is plain abusive not to mention its running without the owner permissions.

AcroRd32Info stay in your memory so consider it as a pest. So how to disabled it?
