The latest scam scenario is still a call from "Microsoft" claiming htey have found errors on your computer and wil fix it for a fee. Microsoft does not call customers. These are absolutely scams. Hang up. If you've already allowed them to "help" you, your computer is infected and will soon begin to show signs of trouble. Next, they'll ca;ll back to check and get even more money from you. I can remove the infection and restore your system to like new performance.
