Dear Pat, I had this happen to me, also. You may continue to get messages on the computer and even phone calls-(the speakers here had India-English accents), claiming to be Microsoft or Apple. Change any of your passwords, as they may have actually have crawled into your system. We have installed Norton's WiFi privacy on our computer which blocks our real IP address. And the visits have finally stopped. Good Luck, and yes, I was lucky my son was in the house when this happened to me.
