Well if they attack your computer systems....it is against the law...and you can take it from there.
i would still report it to your IT guy....
and then add them to the junk mail folder in yahoo....
or change your email address...then they would be..... .flucked ............they could not harrass you any more.
I use web mail accounts for this very purpose....
Did you download or install anything from them...while at work??? Maybe the website they host has some kind of malicious code on it and when you went there (while at work) has dumped some call home program on your machine.
In this case...you need to contact your IT guy to clean it.... ;)
good luck
