Received a call from a man with an Indian accent.  He knew my first name and said he was calling about my computer.  I said "no thank you" and hung up.
Never seen a number with the prefix 4-905.

Got a call from this number on caller ID.  Made the mistake of calling back.  My next phone bill had a long distance charge jammed to my bill from this low-life.  I should have known better.

5PM caller ID says out of area - let answering machine answer set for two rings - no message left. I would be weary about smeone having got my phone number from me using computer let alone telling me I had a virus. Don't answer or hang up seems to be the best way to avoid these nuisance calls.

Rec'd a phone call from a man with an India accent at 3:52pm on May 30th. The number showing on my home was 4-(905) 512-3123. Said that I had downloaded a virus on to my MY COMPUTER Windows #7. Said if I would open my computer he would show me. I ASKED HIM TO CALL BACK IN 5 MINS. In the mean time I called Dell Support

We have been getting these calls regularly from the same number as above. We can not get a straight answer from them & when I called them on being a scam they just hang up. How do I report them?

I got a call from this number.  The man said he was from the National Computer Co and my computer was in danger.  The motherboard had been inffected and I could lose all my data.   I needed to do exactly what he told me to do to save my data.  I hung up.
