Rudi, this is a hoax as are most of these types of e-mails:
http://www.symantec.com/avcenter/ven...a.holiday.html

Win a Holiday is not a virus. It is a hoax. The "virus" does not exist. There is currently no virus that has the characteristics ascribed to "Win a Holiday." It is a sham, meant only to panic new or inexperienced computer users. In addition, it is a mild variant of the "Join the Crew" hoax (form 4).

The hoax message includes one of the following "warnings":


VIRUS WARNING !!!!!!
If you receive an email titled "WIN A HOLIDAY"
DO NOT open it. It will erase everything on your
hard drive. Forward this letter out as many
people as you can. This is a new, very malicious
virus and not many people know about it. This
information was announced yesterday morning from
Microsoft; please share it with everyone that might
access the Internet. Once again, pass this along
to EVERYONE in our address book so that this may be
stopped. Also, do not open or even look at any mail
that says "RETURNED OR UNABLE TO DELIVER" This
virus will attach itself to your computer components
and render them useless. Immediately delete any
mail items that say this. AOL has said that this
is a very dangerous virus and that there is NO
remedy for it at this time. Please practice
cautionary measures and forward this to all your
online friends ASAP.

Second "warning":


WARNING: If you get an E-mail titled : "Win A
Holiday". DO NOT open it. Delete it immediately.
Microsoft just announced yesterday. It is a
malicious virus that WILL ERASE YOUR HARD DRIVE .
At this time there is no remedy . Forward this
to everyone IMMEDIATELY!!

Please ignore any messages regarding this "virus" and do not pass on any messages regarding it. Passing on messages about this hoax serves only to further propagate it.
