Dalantech is correct.
The reason you cannot find any .ZLn files on your hard disk after dealing with
them is that they get transformed into .EXE files if you open them! ZoneAlarm
nags and nags "This is potentially dangerous. Are you sure?" and then
"Are you really sure?" etc, but finally does the dirty deed if you insist.
I had a Windoze Explorer open to the Eudora attachments folder when I did
finally open one such file (after virus-checking it up down and sideways with
multiple AV tools) and....
... I damn near ate my desk when its file extension flipped from .ZL9 to
.EXE before my horrified eyes..
It was benign. But a very nasty moment.
I think ZoneAlarm should provide oxygen cylinders for such times. ;)
All part of the fun, but still..
BTW, thanks for the link to zonelog.co.uk - nice little tool that one.
Take care out there
