here is info from the Symantic virus database on happypark.exe . Those of
us like myself accessing this list via Outlook on an NT machine at work :(
may find this valuable if they opened the attachment.
I verified my registry as clean so as to avoid propagating the little
bastard.
======================================================================
This worm program behaves similarly to Happy99 Worm. It was originally
spread by email spamming from a French email address. The original report
of this worm was submitted through our exclusive Scan&Deliver system on May
28, 1999 from France.
When the attached program file, PrettyPark.exe, is executed, it may display
the 3D pipe screen saver. It also creates a file called files32.vxd in the
Windows\System directory and modifies the following registry entry value
from "%1" %* to files32.vxd "%1" %* without your knowledge:
HKEY_LOCAL_MACHINE\Software\Classes\exefile\
shell\open\command
Once the worm program is executed, it tries to email itself automatically
every 30 minutes (or 30 minutes after it is loaded) to email addresses
registered in your Internet address book.
It also tries to connect to an IRC server and join a specific IRC channel.
The worm sends information to IRC every 30 seconds to keep itself
connected, and to retrieve any commands from the IRC channel.
Via IRC, the author or distributor of the worm can obtain system
information including the computer name, product name, product identifier,
product key, registered owner, registered organization, system root path,
version, version number, ICQ identification numbers, ICQ nicknames,
victim's email address, and Dial Up Networking username and passwords. In
addition, being connected to IRC opens a security hole in which the client
can potentially be used to receive and execute files.
Repair Information
To remove the PrettyPark worm:
On the Windows taskbar, click Start > Run.
Type REGEDIT, then click OK.
Modify the following Registry value:
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\exefile\ shell\open\command
and change
files32.vxd "%1" %*
to
"%1" %*
For clarity, these seven characters are the following: double quote,
percent sign, the numeral one, double quote, space, percent sign, and
asterisk. Don't forget the space.
Delete the PrettyPark.exe file.
Restart your computer.
Delete the \Windows\System\Files32.vxd file.
Safe Computing
Because of Worms and Trojan Horse programs, you must practice safe
computing. Be suspicious of executable file attachments (for example, .exe,
.shs, or MS Word, or MS Excel files), especially ones from newsgroups or
unknown sources. For continuous protection, always run Norton AntiVirus
Auto-Protect and use LiveUpdate to make sure you have the latest virus
definitions.
Norton AntiVirus users can protect themselves from this virus by
downloading the current virus definitions either through LiveUpdate or from
the Download Virus Definition Updates page.
