This number has called me three times in a few hours. 5:15a, 6:30a and 7:30a. i answered the 3rd time and said "stop calling". the person on the other end started saying "why, but why, why??" in a creepy voice. don't answer!
This is a scam call. They will tell you that your Windows program is not working properly and refer you to a certain website which will fix the problem. DO NOT GO TO ANY WEBSITES. This is how they infect your computer with a virus and will then ask for money to remove it. There is nothing wrong with your computer, these people do not work for Windows, Microsoft or any other computer related company. This scam as been all over the news and there are youtube videos showing how this scam works. Best to block this number and tell your family and friends also.
