It's not clear if you're talking about an email virus that associates are getting, or if you're referring to another metaphorical "virus" that's making you popular again.

In the former case, the Klez worm has been circulating since mid-April. I've seen virus intercepts go from a base of 6-24 daily (averaging ~12) Jan - Apr 15, to a constant stairstup up, now currently averaging 250 intercepts daily. Absolutely no sign of it trailing off. We've watched people get infected multiple times.
