Technical Description:

It copies itself in the  "Windows" folder (C:\windows or C:\winnt), with the name "Britney.chm".
It sends an email to the first contact in address book, through the Outlook.

The email has:
"RE: Britney Pics"
"Take a look at these pics...
Regards, "

< user's name >
the virus - a vb-script in a html-page embedded in a chm-file.

In order to send the infected email just once, it creates the registry key
with the value "1".

It also spreads itself through the mIRC. It searches the mirc folder: It searches first the hard disk (drives C:, D:, E: ) in order to find \"mirc.ini\" and second, it searches in registry the key HKEY_LOCAL_MACHINE\SOFTWARE\CLASSES\ChatFile\DefaultIcon\, in order to find the location of the file "mirc.exe".

If it finds the mIRC folder, it creates there a file, "script.ini", which sends the chm-file through mIRC.
