Win32/Maldal.C

New worm: Win32/Maldal.C (alias Christmas, W32/Reeezak.A-mm) has reported in the wild. The worm is a "mass mailer" that comes in an e-mail with the following subject line:

Subject: Happy New Year

The body of the message contains the following text:

Hii
I can't describe my feelings
But all i can say is
Happy New Year :)
bye

The worm is activated when the e-mail attachment: Christmas.exe is executed.

NOD32, version 1.134 detects the infiltration. Infected e-mail should be deleted. The executed worm modifies the starting page of the Internet Explorer resulting in an attempt to open a web page containing malicious script. The latter is detected by NOD32 by means of its heuristic analysis even without the need of the system update.
