someone from this number called me at 8:15 am today saying something about my computer. I have no idea who it was or what they wanted

they called my home phone at 8:15 this morning

Calls from this number and other numbers started about 2 weeks ago all hours of the day and night. When I call back it says the number is disconnected or cannot be completed as dialed. I answered one of these calls when they started and it appeared to be some kind of computer scam. They wanted me in front of my computer and told me my computer has Windows viruses!  I told him to give me his name and phone number to call back and he hung up.  I block every one of these numbers but they just keep coming.  I have to screen every call I get now as this is my business line and I have potential clients coming in from many different numbers. Very frustrating.......

someone from this number called me at 9:45am today saying something about my computer. Was a very heavy Indian or Pakistan accent.

Also received a call from this number "regarding my computer virus". Call came in at 9:20 pm.  I was very rude to the agent who spoke very broken English.  When I later turned on my computer it reported I had several viruses that needed repaired.  Took me almost an hour of turning off and on the computer to get back on line. Number keeps calling and I do not answer.
