The Here You Have virus was simple. A cryptic subject heading and a short message linking to either a supposed PDF document or pornographic videos induced users to click through to a server in the UK that hosted a malicious drive-by virus.

If your organization has not been able to figure out how to do email without these periodic disruptions it might be time to consider alternatives. Hosted or in-the-cloud email services have many advantages.
