As of January 9, 2003, due to increased submissions, Symantec Security
Response has upgraded this threat from a Category 2 to a Category 3.
W32.Lirva.A is a mass-mailing worm that also spreads by IRC, ICQ, KaZaA, and
open network shares. This worm attempts to terminate antivirus and firewall
products. It also emails the cached Windows 95/98/Me dial-up networking
passwords to the virus writer.
When Microsoft Outlook receives the worm, the worm takes advantage of a
vulnerability that allows the attachment to auto-execute when you read or
preview the email. Information on this vulnerability and a patch can be
found at 
http://www.microsoft.com/technet/security/bulletin/MS01-020.asp
.
If the day of the month is the 7th, 11th, or 24th, the worm will launch your
Web browser to 
www.avril-lavigne.com
 and display a graphic animation on the
Windows desktop.

3. Copies itself as Hidden system files to:
%Temporary%\<random string>
%Temporary%\<random string>.tft
%System%\<random string>.exe
%All Drives%\Recycled\<random string>.exe
%Kazaa Downloads%\<random string>.exe
4. Adds the value:
Avril Lavigne - Muse
to the registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
so that it runs when you start Windows.
If the operating system is Windows NT/2000/XP, the worm will register itself
as a service.
5. Creates the registry key:
HKEY_LOCAL_MACHINE\Software\OvG\Avril Lavigne
and various subkeys that the worm uses to keep track of its infection
process.
6. Creates a non-malicious text file %Temporary%\Avril-ii.inf and other
temporary files in the Windows Temporary folder.
7. Checks whether the computer is currently connected to a network. If it is
not connected, the worm will attempt to dial out using the default dial-up
connection profile.
8. Searches the Windows Address Book and files with the extensions .dbx,
.mbx, .wab, .html, .eml, .htm, .tbb, .shtml, .nch, and .idx for the email
addresses. Then, the worm sends the email messages with the following
characteristics:
Subject. The subject is one of the following:

Message. The message is one of the following:
Microsoft has identified a security vulnerability in Microsoft&reg; IIS 4.0
and 5.0 that is eliminated by a previously-released patch. Customers who
have applied that patch are already protected against the vulnerability and
do not need to take additional action. to apply the patch immediately.
Microsoft strongly urges all customers using IIS 4.0 and 5.0 who have not
already done so Patch is also provided to subscribed list of Microsoft Tech
Support:

Attachment. The attachment is one of the following:
Resume.exe
Download.exe
MSO-Patch-0071.exe
MSO-Patch-0035.exe
Two-Up-Secretly.exe
Transcripts.exe
Readme.exe
AvrilSmiles.exe

Complicated.exe
Singles.exe
Sophos.exe
Cogito_Ergo_Sum.exe
CERT-Vuln-Info.exe
Sk8erBoi.exe
IAmWiThYoU.exe
From. The worm uses the default SMTP server of the infected computer, and
then adds either the address of the sender or a randomly selected email
address to the "From:" line of the email.
When Microsoft Outlook receives the worm, the worm takes advantage of a
vulnerability that allows the attachment to auto-execute when you read or
preview the email. Information on this vulnerability and a patch can be
found at: 
http://www.microsoft.com/technet/security/bulletin/MS01-020.asp
.
9. As part of the email-sending routine, the worm creates the temporary
file, %Temporary%\NewBoot.sys, which it (usually) deletes now.
10. Searches for the file Icqmapi.dll, by determining the path of the ICQ
program files. If the worm finds this file, the worm copies it to the
\Windows\System folder and sends itself to all the contacts in the ICQ
contact list.
11. Creates a Script.ini file in the mIRC program files folder. This file
will connect to the IRC channel #avrillavigne and send itself to others who
join any channels that you join.
12. Inventories all the network resources searching for open C shares. If
the worm finds an open C share, it copies itself to \Recycled\<random
string>.exe on the remote system and modifies the Autoexec.bat file of the
remote system to load the worm on startup, by adding the following line:
@win <random string>.exe
13. Copies itself to \Recycled\<random string>.exe on each local hard drive
and modifies the Autoexec.bat file (adding the aforementioned line), so that
the worm runs when you start Windows (on Windows 95/98/Me computers only).
14. Copies itself as a random file name to the KaZaA download folder.
15. If the day of the month is the 7th, 11th, or 24th, the worm will launch
your Web browser to 
www.avril-lavigne.com
 and display a graphic animation on
the Windows desktop.
Symantec Security Response encourages all users and administrators to adhere
to the following basic security "best practices":
Turn off and remove unneeded services. By default, many operating systems
install auxiliary services that are not critical, such as an FTP server,
telnet, and a Web server. These services are avenues of attack. If they are
removed, blended threats have less avenues of attack and you have fewer
services to maintain through patch updates.
If a blended threat exploits one or more network services, disable, or block
access to, those services until a patch is applied.
Always keep your patch levels up-to-date, especially on computers that host
public services and are accessible through the firewall, such as HTTP, FTP,
mail, and DNS services.
Enforce a password policy. Complex passwords make it difficult to crack
password files on compromised computers. This helps to prevent or limit
damage when a computer is compromised.
Configure your email server to block or remove email that contains file
attachments that are commonly used to spread viruses, such as .vbs, .bat,
.exe, .pif and .scr files.
Isolate infected computers quickly to prevent further compromising your
organization. Perform a forensic analysis and restore the computers using
trusted media.
Train employees not to open attachments unless they are expecting them.
Also, do not execute software that is downloaded from the Internet unless it
has been scanned for viruses. Simply visiting a compromised Web site can
cause infection if certain browser vulnerabilities are not patched.
Removal tool
Symantec has provided a tool to remove infections of W32.Lirva.A@mm. Click
here to obtain the tool. This is the easiest way to remove this threat and
should be tried first.
Manual removal
These instructions are for all current and recent Symantec antivirus
products, including the Symantec AntiVirus and Norton AntiVirus product
lines.
1. Restart the computer in Safe mode.
2. Remove the value that the worm added to the registry and restart in
Normal mode.
3. Update the virus definitions.
4. Run a full system scan and delete all the files detected as
W32.Lirva.A@mm.
For specific details on each of these procedures, read the following
instructions.
1. Restarting in Safe mode
Restart the computer in Safe mode. All the Windows 32-bit operating systems,
except Windows NT, can be restarted in Safe mode. For instructions, read the
document, "How to start the computer in Safe Mode."
2. Removing the value from the registry
Symantec strongly recommends that you back up the registry before you make
any changes to it. Incorrect changes to the registry can result in permanent
data loss or corrupted files. Modify the specified keys only. For
instructions, read the document, "How to make a backup of the Windows
registry."
1. Click Start, and then click Run. (The Run dialog box appears.)
2. Type regedit, and then click OK. (The Registry Editor opens.)
3. Navigate to the key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
4. In the right pane, delete the value:
Avril Lavigne - Muse
5. Exit the Registry Editor.
6. Restart the computer and allow it to start in Normal mode.
3. Updating the virus definitions
Symantec Security Response fully tests all the virus definitions for quality
assurance before they are posted to our servers. There are two ways to
obtain the most recent virus definitions:
Running LiveUpdate, which is the easiest way to obtain the virus
definitions. These virus definitions are posted to the LiveUpdate servers
once each week (usually on Wednesdays), unless there is a major virus
outbreak. To determine whether definitions for this threat are available by
LiveUpdate, refer to the Virus Definitions (LiveUpdate), in the "Protection"
section, at the top of this writeup.
Downloading the definitions using the Intelligent Updater. The Intelligent
Updater virus definitions are posted on U.S. business days (Monday through
Friday). You should download the definitions from the Symantec Security
Response Web site and manually install them. To determine whether
definitions for this threat are available by the Intelligent Updater, refer
to the Virus Definitions (Intelligent Updater), in the "Protection" section,
at the top of this writeup.

instructions on how to download and install the Intelligent Updater virus
definitions from the Symantec Security Response Web site, click here.
4. Scanning for and deleting the infected files
a. Start your Symantec antivirus program and make sure that it is configured
to scan all the files.
For Norton AntiVirus consumer products: Read the document, "How to configure
Norton AntiVirus to scan all files."
For Symantec AntiVirus Enterprise products: Read the document, "How to
verify that a Symantec Corporate antivirus product is set to scan All
Files."
b. Run a full system scan.
c. If any files are detected as infected with W32.Lirva.A@mm, click Delete.
