Got a spam claiming to be a cure for the most recent virus, one that most anti-virus software can't detect. Then the warning: because it's a very subtly modified version of the original virus, it might be flagged as a virus by your anti-virus software. So ignore the warnings! They don't know what they're talking about!
(If the anti-virus software doesn't know about the virus it's supposed to be a close relative of, why does it flag the cure but not the disease?)
Oh, and it's sent by "webmaster", and has the obligatory spelling mistake (technique spelled as "technic" - I note that my spell checker doesn't pick that up as a spelling mistake, though, so maybe that's why)
If the virus people want to be smart, they should go through recent received and un-replied email, and reply to it with Eliza (after examining the sort of quoting / replying styles the user tends to use). And, of course, include an attachment. But hey, what am I saying, these are virus people. They almost by definition stupid - anyone smart enough to know how to write a proper virus is smart enough to realise what an astoundingly callous and evil act that would be.
