If you are on a network or have a full-time connection to the Internet, such as a DSL or cable modem, disconnect the PC from the network and Internet. Disable or password-protect file sharing, or set the shared files to Read Only, before reconnecting the PCs to the network or to the Internet.

Because this worm spreads by using shared folders on networked workstations, to ensure that the worm does not reinfect the PC after it has been removed, Symantec suggests sharing with Read Only access or by using password protection.

If you are using a non-standard Master Boot Record (MBR) or if you use encryption on your HDDs or partitions, we recommend that you make a back up before running this removal tool.

Note for network administrators: If you are running MS Exchange 2000 Server, we recommend that you exclude the M drive from the scan by running the utility from a command line, with the Exclude switch.
