Basically some angry, syphilitic spider-shit for brains spammer got a script kiddie to write up a nasty virus to get even with people who don’t want their inboxes cluttered with “re: par1s h1lt0n sux huge black c0x 0|| tape!!!”
It would certainly stop them from infecting home PCs. As for web sites, I’m not sure how they spread from server to server. But they must show up in the logs and therfore be traceable to their source.
No. Most come from people they do know, who have them in their address books, who have been infected by emails from people they know, who had them in their address…
The ones that really need slapped over the head are those who buy stuff from spam. If it wasn’t for them spammers wouldn’t bother.
