Very dangerous!

Running infected files causes the worm to reconstruct the uninfected host file using saved data. Such reconstructed files will have '~1' appended to the name (ex., infected MSOFFICE.EXE will be accompanied by an uninfected MSOFFI~1.EXE). The worm deletes them as soon as the program stops running so they exist only temporarily.

W32/Klez.e@MM sends itself out using SMTP protocol. It harvests the Windows address book for email addresses.

The virus may save a copy of itself into .RAR archives.

There is a date-activated payload associated with this threat. On the 6th day of March, May, September, or November, the virus may overwrite local and network files containing the following extensions with zeros: .txt, .htm, .html, .wab, .doc, .xls, .jpg, .cpp, .c, .pas, .mpg, .mpeg, .bak, or .mp3.

If the month is January or July, all files may be overwritten.
