Adobe Reader BHO help/question

[UselessUser]

Hi,

I am just trying to work out something in regards to Adobe Reader. I am
running XP SP2 with Adobe Reader 8.

It has installed a BHO which I have subsequently disabled, now when I click
on PDF's in Internet Explorer, they open in the browser but I get this
message:

"One or more PDF extensions have been disabled. This may impact how PDFs are
displayed in Internet Explorer. Please go to Manage Add-ons in Internet
Explorer and enable add-ons from Adobe. You will need to restart Internet
Explorer after performing this action."

Now the truth is, I do not want to do this.... I then decided to investigate
BHO's a little more and found the reg key where they exist:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects

In here I have two CLSID's. One is for Java's SSV.dll, whereas the other
correctly correlates to the acroIEhelper.dll file installed by Adobe in the
Program files directory. However I have noted that this CLSID does not have
the NoExplorer DWORD value. Does this mean that whilst Internet Explorer can
not use the extension, Explorer itself can, and this is why it is opening in
IE (Despite the errors), or is there another reason why this is occuring?
Also why would a BHO run with Explorer?? Is this not a security risk?? What
browser helper objects use Explorer rather than IE??

Sorry just a bit mystified about this, and thought I would ask for some
expert advice!

Did you have a question? I did not see one in your post.

If what you want to do is NOT integrate Acrobat Reader in your browser,
go into Acrobat Reader's options (preferences) and disable browser
integration. That will force the browser to download the .pdf and open
in whatever is currently designated as that filetype's handler (which
would be Acrobat Reader).

Useless,
Vanguard is correct. What it appears to us that your doing is not wanting
adobe reader to open while your browsing the web, which is really the only
reason you would want to disable it's BHO. It would be even easier to just
configure Reader to not open them within the browser following the steps that
Vanguard has given.
Reader's BHO in this case is how IE will call to adobe Reader to open within
it's window, essentially it does exactly what it says, it's a browser helper
object, it assists the browser in doing something. Disabling only parts of
an IE add-on can cause application issues like the error message you are
experiencing.

The implied question here is whether the Adobe Reader BHO is a dire threat
to security and the answer is no.
There is no need to disable the BHO unless you do not want .pdf files to
open properly inside IE.
