First of .. personally I haven't had problems with my mailbox getting filled with mails because of this virus, probably because of a simple mailfilter setting
But then I have noticed that something have changed over these last days .. I'm hardly receiving any spam this week!
Usually I receive some 5-10 mails a day .. this week I've gotten 1 or 2
I think it must be because the mailboxes spammers use are being bombed as a result of Sobig.F and then they can't use them .. doesn't that seem resonable
