Hi John. You're right, no infection.
You asked "The one thing I would like to know is, how could this have
happened?"
Well, the behavior started right after I uninstalled MyDefrag v.4.2.6, and
downloaded and installed v.4.2.7. Now, at that point I think everything was
still OK. I wanted to run the new version, so I went to my start menu and
clicked on the icon for MyDefrag. From here on, my memory of exactly what I
did gets a little bit fuzzy. At any rate, I think I checked the properties
for the MyDefrag icon, and it was still targeting v.4.2.6, which I had
already uninstalled. Or maybe when I clicked on the icon, it brought up an
Open With window. At any rate, I definitely remember associating something
with MyDefrag.exe, and I think that was when everything went to hell. It
seemed like anything I tried to open opened MyDefrag instead. After the
fact, I've realized that apparently I somehow corrupted the .exe file
association. Elmo had sent me a link to Doug Knox's website which has XP
File Association fixes. That probably would have fixed my problem, but I
didn't yet realize that. I was just so sure that what I wanted to do was to
do a System Restore that I wasn't into other alternatives. I was just about
ready to try the Safe Mode approach to System Restore when my wife needed to
use the computer. I told her I had screwed the computer, but she was welcome
to see if she could access anything. By this time, I had realized that it
was only .exe's that were opening MyDefrag, and I thought maybe she could do
what she wanted without clicking on an .exe. Well, I realized when she got
on her userid, she could open .exe's with no problem, so as soon as she was
done, I ran %systemroot%\system32\restore\rstrui.exe in the start run box,
like John John had told me earlier. System Restore came up, I restored to
the previous restore point, went back to me userid, and everything was good
again.
That's about the best I can reconstruct the situation. In retrospect, it
seems like it was awfully easy to mess up the computer. Nothing gave me a
red flag, or warned me I was about to do something dumb. I'm still really
not exactly sure what it was that I did. I was just trying to answer the
computer's question of what did I want to open MyDefrag with, and I said
MyDefrag. All's well that ends well. Right?
