That happened to me also and it is sure a nusience. I hope you got everything straightened out without too much trouble. My computer geek explained to me that often it is kids thinking it is fun to hack into someones email address book and start sending these things-NOT my idea of fun! Good of you to remind everyone again that we need to be careful.
I am sorry your computer caught a virus. I hope you did not loose your embroidery files and had them backed up.
