I have one customer somehow overtaken and sending encrypted Zip files to her contact list. The beauty is that the filters bypass encrypted files with the comment UNCHECKED. Thanks so much...
First, does anyone have info how to stop this virus/worm? The latest I saw was:

zip password 1234567
Don't hesitate to ask me any questions.
