<h2><font color=#003399>Lirva worm attaches to Avril Lavigne
</font></h2>
The popularity of singer Avril Lavigne has spread to the world of computer viruses.

Lirva (w32.Lirva@mm), also known as Naith, is a mass-mailing worm that is UPX-compressed to a file size of 32,766 and arrives via e-mail either announcing a new Microsoft patch or offering fan access to Avril Lavigne.

Once active, Lirva will attempt to e-mail copies of itself to all contacts on an infected system, shut down all antivirus and firewall programs, and launch a Web browser to open the Avril Lavigne Web site on an infected user's desktop.

Lirva uses the Iframe vulnerability, so on unpatched systems, the worm will automatically execute whether or not the attached file is opened.

Antivirus vendor MessageLabs reports that parts of the Lirva worm code very look familiar, so Lirva may turn out to be a variant of a known virus family.

Because this worm sends e-mail but is not considered destructive, it rates a 4 on the ZDNet Virus Meter.

Once active, Lirva will attempt to shut down all security programs such as antivirus and firewall software.

Prevention
Users of Microsoft Outlook 2002 and users of Outlook 2000 who have installed the Security Update and have installed the patch for the MS01-020 vulnerability in Internet Explorer should be safe from Lirva. Users who have not upgraded to Outlook 2002 or who have not installed the patch for the MS01-020 vulnerability should do so. In general, do not open attached files in e-mail without first saving them to hard disk and scanning them with updated antivirus software. Contact your antivirus vendor to obtain the most current antivirus signature files that include MyLife.

Removal
A few antivirus software companies have updated their signature files to include this worm. This will stop the infection upon contact and in some cases will remove an active infection from your system. For more information, see Central Command, McAfee, Sophos, and Trend Micro.
