Attached File: pp-app.zip

The file pp-app.zip contains a copy of W32/Mimail-N with a random filename.

W32/Mimail-N creates a copy of itself named ee98af.tmp and a copy of pp-app.zip named zipzip.tmp, both in the Windows folder. The worm also creates other helper files that are non-malicious and can simply be deleted. Such files may include:

C:\tmpcan3.txt
