Type:
Worm

This script is intended to be a mass-mailing worm that spreads using mIRC and Microsoft Outlook. The samples of the worm that the Symantec AntiVirus Research Center (SARC) has received from customers were not able to spread due to bugs in the worm's code. Because of this, on July 5, 2001, the threat assessment was downgraded from level 2 to level 1.

NOTE: Virus definitions prior to June 28, 2001, detect this worm as Bloodhound.VBS.Worm



All samples received by SARC have a minor bugs in them which cause the worm not to work as intended.
