W32/ExploreZip.worm is a worm that infects Windows systems. It is very dangerous, potentially more destructive than Melissa. It reproduces itself by sending replies to incoming email messages, with itself as an attachment called "zipped_files.exe". It includes a payload: it will search the user's hard drive and delete all files of types .c, .cpp, .asm, .doc, .xls, .ppt.

IMPORTANT: If you receive an email with the message:

"I received your email and I shall send you a reply ASAP. Till then, take a look at the attached zipped docs."
