I just had a call from the same number.  Guy with heavy Indian accent claimed to be from PC Wizard.  He called me by name and read my address back to me.  When I asked how he knew I had a problem with my PC he said 98% of MS Windows users do.  I asked if he worked for Microsoft and he said "No, do you think Microsoft would call you about your computer problems?  They are the manufacturer of your computer!"  Long story short, I kept asking him how he knew I had a problem and he said "OK, I am telling you I am from Microsoft...are you happy now?"  LOL.  I asked him to take my name off his calling list and he started getting more belligerent.  At that point I asked to speak to his supervisor and he said "You know in a million years that is not going to happen."  I told him I wasn't going to answer any more of his calls and hung up on him.  Geez these guys are annoying!  If they call back I'm going to use some of the tactics above to have some fun with them.

Called claiming I have a virus on my computer, didn't use correct terminology, Scam of the first order.  Indian voice.  Asked to be removed and he laughed and hung up.

Call ID = Name Unavailable

I just got a call which I have on my block list.  I get no ring but I do get a list of blocked calls on my phone. See below.

I have the Panasonic cordless telephone  Model kx-tg6842b (2 handsets)
You can block 250 numbers plus kill the one ring that existed on earlier models that only allowed 30 blocked numbers.

The one handset model sells for $70 at Amazon.

Called and said I had a problem with error codes being sent from my computer.  Wanted me to turn on my computer and open up files so he could walk me through the fix.  SCAM.

Called claiming I have a virus on my computer, didn't use correct terminology, definitely a scam.

Called and asked for me by last name but hung up once they realized it was a machine getting the call.
