Brief Description 


Hybris.A is a worm that reaches computers in a file attached to an e-mail message. The sender of this message is Hahaha < > and the subject of the message in English is Snowwhite and the seven dwarfs-The REAL story!, but there are also versions in Spanish, Portuguese and French.

The danger of Hybris.A lies in its capacity to spread. It does this by controlling the e-mail message sent from infected computers. When the user sends an e-mail message, the worm waits a while and then sends another message.

When Hybris.A activates, it infects files with an EXE extension. Every November 24, it also displays an animation of a spiral on the Windows desktop.
