The reason people are getting so many is because of this read it Last week on the BBC web site
A war of words is breaking out between the creators of the Netsky, Bagle and MyDoom Windows worms.
The malicious programs' creators are putting taunts and insults in successive variants of their viruses.
The spat began because Bagle's creators are jealous of all the media attention that the Netsky virus is getting
Anti-virus firms discovered the insults inside the viruses when they were being taken apart to find out how they differed from earlier versions of these malicious programs.
Inside Bagle.J, along with a string of profanity, is a message reading: "don't ruine (sic) our bussiness, wanna start a war?"
The response to this seems to be inside Netsky.F, released the day after Bagle.J, which contains a message reading: "Bagle - you are a looser!!!! (sic)".
So it looks like its going to be a long hall of virus deleting if it carries on for long enough they could make an olympic event out of it
