PREVENTION:
Outlook 2000 post SP2 and Outlook XP SP1 include the most recent updates to

configured to block Zip file attachments but does not do so by default.
To ensure you are using the latest version of Office click here:
http://office.microsoft.com/ProductUpdates/default.aspx
By default, Outlook 2000 pre SR1 and Outlook 98 did not include this
functionality, but it can be obtained by installing the Outlook E-mail
Security Update. More information about the Outlook E-mail Security Update
can be found here: http://office.microsoft.com/Downloads/2000/Out2ksec.aspx
Outlook Express 6 can be configured to block access to potentially-damaging
attachments. Information about how to configure this can be found here:
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q291387
Outlook Express all other versions: Previous versions of Outlook Express do
not contain attachment-blocking functionality. Please exercise extreme
caution when opening unsolicited e-mail messages with attachments.
Web-based e-mail programs: Use of an application-level firewall can protect
you from being infected with this virus through Web-based e-mail programs.
RECOVERY:
If your computer has been infected with this virus, please contact your
preferred antivirus vendor or Microsoft Product Support Services for
assistance with removing it.
As always please make sure to use the latest Anti-Virus detection from your
Anti-Virus vendor to detect new viruses and their variants.
If you have any questions regarding the tool or its implementation after
reading the above resources, you should contact Product Support Services in
the United States at 1-866-PCSafety (1-866-727-2338). International
customers should contact their local subsidiary.
