I-Worm.Pepex

Worm Pepex spreads via the Internet. It can arrive in infected e-mails with attached files, by file-sharing or IRC networks. It installs itself to the computer and uses remote mail servers to distribute itself to e-mail addresses found in some HTML files. It also modifies mIRC chat client's settings and places infected files to shared folders of the KaZaA peer-to-peer software and spreads using this software.
