In January 2015 I received a pop-up from "Microsoft" stating I was infected with a virus and to call a phone number. I called the number and was connected with someone and got the problem resolved. Little did I know that the person was from Core It Resolve who is now calling me at least 5 times a day and will not stop calling saying my computer is hacked trying to get me on my computer. This was not a Microsoft issue and they entered this on my computer somehow to get me to call them. According to the info on the internet this is a scam company and and a lot of people are experiencing the same problems. They are out of San Pedro, CA and call from an Unknown Number. Just wanted to give everyone a heads up. I should not have been no naive!!!
