I just recieved a call from someone saying he was calling to say that my computer has been downloading spyware and other malicious software and could crash at any time. I asked for a supervisor and said how did you get my number and what is my name...and they actually knew both. I asked where they were located and they said headquarters in California.....caller ID said Washington. I said what do you want me to do? I said I would not do anything without proof of who they were.....I told the supervisor not to call my home again that I would report them to the Better Business Bureau and to the Local Police Dept.......She said Merry Christmas and hung up...Both had very thick accents. She told me to turn on my computer and I said NO....I was afraid they were hackers and scared they would send me a vkrus. Weird.
