Open File - Security Warning

R

Rich Pasco

I'm running Windows XP.

Within the last week, every time I double-click on a JPG image file in
Windows Explorer (or type its name on the command line), I get:

Open File - Security Warning
Do you want to open this file?
... [Open] [Cancel]
[x] Always ask before opening this file
While files from the Internet can be useful, this file type can
potentially harm your computer....

I can un-check the "Always ask" box, and then it doesn't prompt me any
more for that particular image, but it still prompts for other JPG images.

Can anyone explain why I am suddenly getting this prompt?

Could it be that recently I installed Firefox 3.0?

How can I disable this prompt for *all* JPEG images, regardless of how
I acquire them?

If I right-click on a newly-downloaded image and choose Properties,
At the bottom of the General tab it says:

Security: This file came from another computer and might be blocked
to help protect this computer. [Unblock]

It only says this for images downloaded with Firefox 3.0.1, not images
I had previously downloaded with 2.0.16. Clicking [Unblock] has the
same effect as un-checking "Always ask": it only affects that one file.

Apparently XP maintains a "blocked" flag in the file properties. This
is news to me. I want to make all JPG images automatically unblocked.
This could be by either (a) fixing Firefox to store images without the
"blocked" flag, or (b) fixing Windows to ignore it.

Suggestions?

I found some useful information at Experts Exchange:

for XP Pro:

1. Click Start, Run and type GPEDIT.MSC
2. Navigate to: User Configuration | Administrative Templates
| Windows Components | Attachment Manager
3. Double-click "Do not preserve zone information in file
attachments"
4. Set it to "Enabled"

Unfortunately, this only prevents newly-downloaded files from being
flagged as suspicious. It does not stop Windows from warning me
about files which were already downloaded and flagged.

Also the aforementioned control affects all files equally, when I
wanted to handle JPG files specially.

You are a your own Self Help Guru!

I wonder, what if you E-mail the pictures to yourself. Will that remove the warning?
