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.

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.

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?

Called today saying computer infected, my wife handed off to me and he hung up on my questioning.

I also had a call 2 times from the number and I just did not argue with them and hang up. They are now trying to phone people in Malta, therefore be careful, do not do anything with your computer just hang up.
