Notepad.exe tries to connect to the internet

Hausi Tellenbach

Hi all.

I have Windows XP Professional Build 2600.xpsp2.030422-1633 (Service Pack 1)
with all available Critical Updates and Service Packs from
windowsupdate.microsoft.com and also from officeupdate.microsoft.com.

My personal firewall (KPF 4.0.16) asks me to allow Notepad.exe a connection
to ftp.leo.org [131.159.72.23], Port ftp [21] as soon as I choose "Save
as..." or "Open..." in the notepad.exe...

Notepad.exe to the internet? I remember, there was TROJ_QAZ, but neither the
antivir with actual signatures, nor my investigations in the registry and
folders let me find any part of a trojan or of an other malware. I also
"asked" google, but I couldn't find any hint about this. Also Regedit and
"Search..." "containing ftp.leo.org" didn't let me find a clue.

Yes, I remember: Long time ago I was on ftp://ftp.leo.org/pub/freedb an I
droped the Icon from the IE-Adress Bar as shortcut (freedb.url) to the
desktop - is it possible, this is the reason?

After deleting freedb.url, notepad.exe didn't ask anymore to connect to the
internet - if I place the shortcut again to the desktop, Kerio ask me
again - it's reproducable. I noticed, desktop was the last place I saved a
..txt-file - so I tried to move the freedb.url to My Documents, saved a .txt
there and tried again. Now My Documents was the last place and as soon as I
choosed "Save as..." or "Open..." from notepad.exe, Kerio asked me to allow
notepad.exe to connect to the internet. I've tried it again with a test.url,
which points to a http-site - no connection asked -> only for ftp-sites.

=> If there is a .url which points to an ftp site in a folder, which was the
last place notepad stored a file, notepad.exe will try to connect to the
location of this .url as soon as I choose "Save as..." or "Open..." - No
malware, but reproducable!

So, I'm wondering, what's the reason? Can I do something to correct this
behavior? Am I the only one, who is able to reproduce this behavior?

Where'd you learn of this ftp site? Do you program or write private info.
with Notepad? If so, you may be compromised. I myself didn't try to
recreate the problem, as it sounds pretty suspicious. The following is the

Not quite. Explorer (or the shell) is verifng the shortcuts (eg the File Open window). Windows hates FTP, it has a problem with FTP bad (it hangs till the ftp site answers). It should also happen at bootup. Put it in favourites. I can't connect to that site.

Hi Mary.

As I wrote - it's neither the qaz, nor an other malware - I've checked every
entry in startup (hklm, hkcu, startup-folder (pers and common), even
win.ini, etc.)
=> No unknown entry - it happens even if I disable some unnessesary stuff in
the startup with msconfig and what's not enabled, I've nothing found about
the left entries in google (web and news) - there is also no unknown service
and neither antivir, Spybot nor Adaware, etc. has detected a malware.

I think, my PC is really clean
