I received a call from this number ("Ohio") after 10:30 at night.  The caller was a woman with an Indian accent who claimed to be from the "Internet Security Department".  She said she was calling because people in other countries were using my computer to infect others and that I needed to help stop it.  I let her keep going until she prompted me to start typing a command to run and then I hung up.

these "collections agent" dicks called at 11:30 PM and woke up the house to tell me that we owed them for a comcast bill... we have never had comcast.. much less have an outstanding bill at damn near midnight...

Called here (Southern Calif) at 10:00 pm. Answered only because I know folks in that area code and it said "Univ Hosp"
No message when I answered...they hung up.

1 216-201-4565 this guy thought I was stupid, he had a strong middle eastern voice, Anyways he said he's from Internet security and that he believes my Internet has been compromised. I told him I don't have Internet and he hanged up. Lol...
