Hi. I'll try to be cogent, but I'm a little under the weather.
It is really important to distinguish between Windows Explorer and Internet
Explorer (and, of course, other browsers).
You've said that you're using IE7, which is probably good. IE7 has the
ability to help you control, to a very great extent, the behavior of any
Add-ons (Browser Helper Objects / Browser Extensions) that you may have
installed. Just go to the Tools | Manage Add-ons | Enable or Disable Add-ons
location in IE7. There's a drop-down at the top of that dialog that lets you
Add-ons that have been used by Internet Explorer
Add-ons currently loaded in Internet Explorer
Add-ons that run without requiring permission
Downloaded Active-X controls
You will need to look through those and study them to get a solid feel for
what they are and where they come from. IE7 has an excellent online help file
system. You'll want to use it to do your basic research and then look up your
add-ons to be sure whether or not all of your add-ons should be there.
Windows Explorer can also have add-ons added to it. Popular ones do things
like add toolbars or right-click context menu options. All such applications
SHOULD put some kind of entry into your Add/Remove Programs dialog. Sometimes
the entry in Add/Remove Programs has a name that isn't very similar to the
name of what you installed. I wouldn't trust any installer that violates
proper etiquette in this respect.
I suggest avoiding the addition to IE7 of things like download accelerators
(Microsoft's own download manager is okay, though.) and things that control
basic browser features like whether or not scripts will run. The browser is
quite capable of handling all of this itself. And most, if not all, of these
"enhancements" that I've seen are smoke and mirrors. You may need plug-ins to
handle Flash, Adobe Acrobat, Quicktime, Real, and perhaps other popular
online file formats. But adding anything that interferes with or supplements
IE7's own control over its own internal functions is probably just asking for
I'm concerned about your Java support. My Sun Java applet is Standard
Edition 6 version 1.6.0 (build 1.6.0-b105) and was just downloaded from
http://www.java.com yesterday. But I don't use the Sun JRE to support IE7. I
install it (custom installation option) for use with Mozilla Firefox 188.8.131.52.
I also use a plug-in named NoScript for Firefox. I turn off all scripting by
default and enable it TEMPORARILY at each Web site I visit it on a
case-by-case visit. That's how I browser everywhere but KNOWN good sites. I
do my slumming with Firefox because that security arrangement just works
better for visiting unknown sites -- in my opinion. But if you have an older
version of the JRE installed that needs to be replaced right away.
You can turn off all scripting for ordinary Internet sites in IE7, too, and
just add sites one-by-one to the Trusted category. That's a little less
convenient and can result in a few odd issues with Windows / Microsoft
Updates until you get it all sorted out.
I hope I haven't misunderstood your message and that my attempt at "advice"
is not confusing. It is necessary for me to be a little vague here because it
would be very hard for us to really nail down the exact configuration of your
browser and all of the ramifications thereof. Basically I'm saying that you
need to do some research and some real soul-searching on this issue of
add-ons in this operating system. The Internet Explorer and Windows Explorer
functions are integrated very tightly into the OS and can have far-reaching
effects upon it. It is important to avoid installing anything for which you
do not have a clearly demonstrated need. Even then, no matter how badly you
feel you need a given function it is best to avoid installing it unless you
have done some research to be sure that it is trustworthy. (Popularity of a
piece of software is usually NOT a good criterion to use for establishing its
On my system I use Quicktime Alternative, Real Alternative, Adobe Flash, and
Adobe Acrobat plug-ins for IE7. Those are the only IE plug-ins on my systems
other than those that Microsoft actually provides with IE7 in Vista RTM. (I'm
a TechNet subscriber and am using Vista Business for testing on my personal
systems right now.) Any time I'm tempted to install something else I remember
how many people I've helped people fix their systems after they installed
Good luck. And I hope my message isn't as muddle-headed as I feel.
Thanks mate, You're right regarding the add ons for my browser which is IE7..
I installed 'DAP' [download accelerator plus] the other day and now i can see
the connection DEP, DAP its all coming together [smile]. And more recently,
yesterday in fact, 'PopUpBuster' from ECOM software. Thereis an option in the
setup of the latter to 'enable script links [Enables executing Java and
VBScript links]' which i've just checked and it isn't enabled [unticked]
which is the way it would have been at the time as I haven't changed it.
-- Iv'e just reread your reply and think I may have misunderstood. I don't
know about anything placing extentions, add ons in windows explorer.
PopUpBuster runs from explorer, is activated from win exp. Ther is no entry

All I can tell you about Java is that it's Java 2 platform standard edition

The DEP message you received may, or may not, have been related to the Web
site for which you received a warning.
I have two suggestions to make, and I hope others will chime in if there are
other matters I'm overlooking.
specifically, as well as a warning while visiting that Web site -- which
browsing to sites with unknown characteristics I strongly suggest NOT
enabling scripting in the browser (regardless of brand or version of the
browser). Enable scripting ONLY for sites that you trust on a one-by-one
basis. This is accomplished by different methods in different browsers. You
don't want to get a step-by-step for this from someone on a newsgroup. You
want to do the research yourself so that you understand how and why your
browser works the way it does. But the bottom line is -- no active scripting
allowed unless YOU specifically allow it for the site you are visiting.
Regardless of which browser you are using always make sure that your
that covers all of the common software sources is the Secunia security
advisory. There are others. Subscribe to one via RSS or e-mail. Read every
issue to be sure that you have applied patches or workarounds for every item
that applies to your systems. There have been fairly recent updates to the
Microsoft scripting support for its browsers and for the Sun JRE, which
supports other browsers like Firefox as well as IE.
Regarding DEP closing Windows Explorer (not Internet Explorer), if I
understood your message correctly this is what happened to you, and I suspect
that it probably doesn't have anything to do with the Web site you mentioned
-- unless you installed something from that site on your system. (Some of the
techniques used for getting us to install stuff can be pretty insidious.)
But I'm guessing that you have an application installed that places an
extension or add-on in Windows Explorer. I can give you an example with which
I have personal experience. In Windows XP Pro SP2 I kept receiving occasional
Windows Explorer shutdown messages from DEP. I finally traced it to an
application named SnagIt which installed a plug-in or extension for Explorer.
All I had to do to eliminate the issue was to tell the SnagIt installer NOT
to install that context handler -- or remove SnagIt altogether. Because
SnagIt's plug-ins were also causing problems with some Office apps I just
blew SnagIt off the system -- though I had used it for years. I found other
ways to get the functionality I needed. Pretty easy to do in Vista RTM.
I think you need to check to see if you have something on your system that
adds extensions to Explorer. Eliminate all such items temporarily, see if the
problem occurs again. If not, add them back until it does. You might also
extend DEP to cover all applications, rather than just the Windows components
that it covers by default. That's what I do. That setting may warn you about
behavior from an application which could cause failures in Explorer or other
Sorry for the rambling. Not enough coffee yet this morning.
I got a message from DEP [data execution protection] telling me that it had
to close win exp for security reasons so as well as doing this I clicked the
link for help on this subject. It explained the steps to take if DEP takes
action and these were pretty standard security measures [scan etc] It also
said something about when it is ok to use the affacted app again but being
windows explorer I don't see as I have a choice. My AVG had just done its
scheduled scan and come up with nothing and i have used win exp since with no
problems so is it possible this was a glitch or something? The only possible
breach of security I can think of is last night 'java' gave me a security
warning about a web site whilst browsing. It gave me the option to either
continue to the site or cancel, i cancelled but still appeared to go to the
site. I have just updated java and AVG is up to date too. Any light shed on
this would be much appreciated thanks.
