Illsei is an Internet worm that spreads by e-mail through messages with infected attachments. Bogus letters are in Spanish. Once installed, the parasite infects Task Manager, disables Registry Editor and System Restore. It also lowers security-related system settings. Illsei uses its own mail engine to send malicious e-mails to all the addresses it finds in local documents, web and mail program files. The worm secretly runs on every Windows startup.
