A friend of mine is getting lots and lots of bounced emails that she never sent ... she was worried she had a virus on her computer, but I explained how most email virusses work. It calmed her down a a bit until her boyfriend told her he has the same problem with bounced emails that he never sent.
Right now I get perhaps two or three virusses-attachments sent to me each day, most of them are recent virussses, but every now and then Klez still pops up. I wonder how long it'll take before that one will finally be gone.
By the way, I read on Cnet.com that some "expert" said that Sobig is probably the first virus made for money gain, and that the current version (F) won't be the last. Read this for more info :)
