The Unknown Caller: You may receive a call that your computer security has been compromised and that they can help you, or that your grandchild is in jail and in need of money. In either case, it is a cold call that has come out of the blue and is asking you to take action quickly and send money now.
How to spot the scam: Any cold call you receive should ask for the caller’s name, and other verifying details including a phone contact for a callback and end the call. If it is someone who claims to be a family member, check with other relatives. If it is a service-related company, search for the company’s contacts on the website and look out for any scam warnings posted online
