This variant nfects the global tempate when an infected document is opened or closed. After that all documents that are either opened or closed in Word will be infected by the virus.

Beside replication, the virus will activate its payload at 10th, 20th and 30th day of every month when a document is closed. At this point, W97M/Xaler will modify "C:\AUTOEXEC.BAT" so, that the following messages will be shown after the system is restarted:

Regardless of the message, this variant does no delete any files from an infected system.
