I expect that as usual, the people who stupidly don't have a good antivirus installed will have their PCs bombard the rest of us with useless junk mail, slowing everything down. But that happens every day.
Short of boiling those stipid, selfish people in their own juices, along with their PCs and the malicious thugs that write viruses, there's not much to do about it.
I suspect tomorrow will have echoes of the millenium bug and life will carry on more or less as usual.
