ILOVEYOU

[hardcore]

JoeyBlades, the Sophos site says this about the Love virus:

But can’t I get infected just by reading or even deleting the email?
No! Some people are saying so. But as with most email viruses, you have to activate the attachment by double-clicking on it.

Again, this particular virus doesn’t propagate simply by viewing the email, regardless of the preview pane. But it is technically possible to create one embedded in html code that would execute if you didn’t have Active Scripting disabled in Outlook.
