I-Worm.KakWorm

Worm KakWorm spreads in the Internet in infected messages without attachments. It infects a PC immediately after a user opens an infected message for preview. That is possible because the worm is written in Java Script language. Also it works only on specific computers: it needs Microsoft Outlook Express mail client installed in English or French versions of the Windows operating computer. The KakWorm doesn't work in other environments. After the infection it places some files on a hard disk and sends its copies to other users. Although this worm doesn't remove your files or documents, it is very difficult to recognize and cure it: most modern antivirus software doesn't detect it.
