Advice
Do not forward hoax messages.
Hoax warnings are typically scare alerts started by malicious people – and passed on by innocent individuals that think they are helping the community by spreading the warning.
Corporate users can get rid of the hoax problem by simply setting a strict company guideline: End users must not forward virus alarms. Ever. It's not the job of an end user anyway.
If such a message is received, end users can forward it to the IT department but not to anyone else.
