Beware of the Scam Calls that come in telling you that they are from Microsoft and your computer is either infected, or about to crash. They have a story that tells you about how they are Microsoft and your computer has come up on their screens and blah blah blah. This is a complete and total scam. So please listen up.
Number one. Microsoft does not will not and never has cold called you! (read that 3 or four times please)
Number three. Read one and two again and never, I repeat never let a cold caller connect to your pc or your credit card. (did I say never). These guys are trained like the closers at a time share sales promotion. They will tell you anything to get you to give them control and money.
A quick story of how one friend handled this. He was in a playful mood and decided to listen to these scam artists and they talked and thought they were guiding him to a particular site. Little did they know he was just doing his normal surfing. They requested him to tell them what was on the screen. He said (a complete fabrication) it says ice cream is on sale. The virus scam artist them said “oh my! You have the dreaded Chinese Ice Cream Virus. We must connect to you immediately.” So as you might expect, after a hearty laugh, he hung up. You would be well advised to do the same.
